From mid-morning to late-afternoon, the heat reached more than 40 degrees Celsius, blowing hot air in every corner from the countryside to the city, the demand for electricity increased continuously for many days and the transmission grid always at the full load warning threshold. In order to ensure the safe operation of equipment on the transmission grid, the National Power Transmission Corporation (EVNNPT) requires units to strengthen the inspection and monitoring of transformers, resistance, current transformers, etc. voltage transformers, pole clamps, connections on lines, substations. In particular, special attention should be paid to the full-load 500kV transformers such as Viet Tri, Hoa Binh, Nho Quan, Thuong Tin, PleiKu 2, Dak Nong, Vinh Tan and the North – Central 500kV lines. Troubled hot season Deputy Director of Power Transmission Company 3 (PTC3) Ho Cong said that by May 2021, the total installed capacity of solar power will be connected to the PTC3 transmission grid and the distribution grid of Power companies in the region. the area of ​​the provinces: Khanh Hoa, Phu Yen, Binh Dinh, Gia Lai, Dak Lak and Dak Nong has reached 4,093MW, accounting for 36% of the total installed capacity of power sources connected to the transmission and distribution grids in the region. this. In which, the connection at the voltage level of 500kV is 600 MW, at the voltage level of 220kV is 753 MW, at the voltage level of 110kV is 940 MW, and the farm and rooftop solar power connected at the voltage level below 22kV is 1,801 MW. With the very fast development speed of solar power plants, farm solar power, rooftop solar power in a short time, some 220kV transmission lines have been built in Phu Yen, Binh Dinh, Gia Lai and Dak Lak areas. and Dak Nong always operate at full load, overload occurs in the rainy season of the Central Highlands. Especially the 220kV transmission lines: Sinh Mass An Khe – Pleiku (100%); An Khe Biomass – An Khe Hydropower Plant (100%); Quy Nhon – An Khe Power Plant (99%); Quy Nhon – Tuy Hoa (96%); Tianjin – Nha Trang (98%); Nha Trang – Krong Buk (87%); Krong Buk – Pleiku 2: (88%) Dak Nong – Buon Tuahar (102%); Dak Nong – Buon Kuop (99%) and AT1 transformer (97.%), AT2 (96%) 500kV Dak Nong substation; transformer AT1 (94%), AT2 (95%) 500kV Pleiku 2 station; transformer AT1 (100%), AT5 (94%) 500kV Pleiku station… When the power grid is operating in a state of full load or overload, PTC3 must request units to increase the frequency of inspection and monitoring of equipment, transformers, lines and corridors to promptly overcome and handle handle unusual phenomena. In addition, some repair and maintenance works that need to be cut off or periodically tested must be arranged at night when solar power stops generating. The implementation of safety measures, as well as the process of construction supervision, supervision of load-bearing equipment, safety control at poles that cross with medium and low voltage lines and roads at it is dark, at night it will be very difficult, potentially dangerous.

Photo: Ngoc Ha/Icon.com.vn According to the document No. 795/TTg-CN dated June 25, 2020 of the Prime Minister on adding the list of wind power projects to the electricity development planning, wind power plant projects in the Central Highlands region. with a total capacity of 2,358MW (accounting for 21% of the total installed capacity of power sources connected to the transmission and distribution grids in this area) is in the process of construction, installation, and putting these projects into operation. November 2021 will put more pressure on the existing transmission grid, which is already full and overloaded in the provinces: Khanh Hoa, Phu Yen, Binh Dinh, Gia Lai, Dak Lak and Dak Nong. In particular, in Gia Lai area, there is a total capacity of 1,242.4MW (voltage level 500kV: 200MW, 220kV: 650MW, 110kV: 392.4MW); Dak Lak area has a total capacity of 685.8MW (voltage level 500kV: 400MW, 220kV: 200MW, 110kV: 85.8MW); Dak Nong area has a total capacity of 430 MW (voltage level 220kV: 380MW, 110kV: 50MW), when put into operation, it will continue to overload 220kV lines of Yang Trung – Pleiku 2 wind power plant; An Khe – Pleiku Biomass, An Khe Biomass – An Khe Hydropower Plant; An Khe – Quy Nhon Hydropower Plant; Krong Buk – Pleiku 2, Dak Nong – Buon Tua shar, Dak Nong – Buon Kuop and AT1 and AT2 transformers at 500kV Dak Nong substation; AT1, AT2 500kV Pleiku substation 2. As a line soldier, the sun also goes to the line, the rain also goes to the line, as a station soldier, flood, or hot weather must be on duty 24/24. In order to mobilize sources effectively, in the current conditions, EVN requires the Power Transmission Companies to transmit the maximum mobilized capacity of the power plant cluster at 100% until the congestion or overload is reached. The associated load is removed. With this requirement, the new operating status of the PTC3 grid is often at 100% full load. Thus, it is necessary to keep the current flowing smoothly in all situations, especially on hot sunny days. With a “hot” area like PTC3, all units, regardless of whether they were on duty or off duty, must gather their manpower to check the grid’s congestion points, the points with high risk of heat generation. The point of line cross-section is small compared to the whole line, the rated current of the equipment in the exposed compartment is smaller than the line, the points have a large deflection, the risk of breaking the distance when the load is high..etc and so on and so forth. problems can occur when the temperature reaches more than 40 degrees Celsius and lasts for many days. It can be said that the transmission shifts during the heat wave are no different from the ones on duty during the flood season. After detecting the risk, it is necessary to propose to reduce the rated current of the line; if the ambient temperature rises suddenly, it is necessary to monitor that the conductor temperature does not exceed the allowable level; make a plan for temporary handling and a plan for long-term handling of bottlenecks of the power grid, determine the time for remediation, and submit it to the Company. For example, during the recent heat wave in May, the transmission units must make statistics of the number of enhanced inspections from the beginning of 2020, thereby proposing a reasonable plan to arrange human resources for the new operation situation; propose the addition of production equipment and tools to serve the operation management in the new operating situation, make a list of proposed equipment to be added immediately.

Head of PTC3 Dispatch Department Nguyen Manh Tuong said that in the first 5 months of 2021, the electricity output received by the PTC3 transmission grid under management and operation reached 23,918,261,392 kWh, an increase of 16.30% over the same period in 2020; delivered electricity output reached 23,445,807,704 kWh, up 16.10% over the same period in 2020; power output received on the 500kV grid reached 17,223,481,412 kWh, an increase of 26.40% over the same period in 2020; electricity output delivered on the 500kV grid reached 17,000,463,190 kWh, up 26.26% over the same period in 2020; power output received on the 220kV grid reached 13,549,084,784 kWh, up 29.86% over the same period in 2020; electricity output delivered on the 220kV grid reached 13,299,649,317 kWh, up 30.08% over the same period in 2020. Despite this output, the transmission output of Power Transmission Company 3 (Khanh Hoa, Phu Yen, Binh Dinh, Gia Lai, Dak Lak, Dak Nong, Ninh Thuan, Lam Dong, Binh Thuan power transmission lines) assigned to Power companies under the Central Power Corporation (EVNCPC), the South (EVNSPC) and power plants (ND, DT, Solar, EIA) in the first 5 months of 2021, reaching 2,826,264,307 kWh, down 37.85% over the same period in 2020, accounting for 49.18% of commercial electricity output of 9 Power companies. The highest transmission power output in May is May 16, 2021 at 22,436,520 kWh. The main reason for the decrease in transmission power output is due to the performance of commercial power production of Khanh Hoa, Phu Yen, Binh Dinh, Gia Lai, Dak Lak, Dak Nong, Ninh Thuan and Lam Power companies. Dong and Binh Thuan under the Central Power Corporation (EVNCPC) and the South (EVNSPC) in the first 5 months of 2021 reached 5.746 billion kWh, a low growth rate, reaching only 0.67% over the same period in 2020. Meanwhile, the electricity output of 110kV solar power, 22kV farm solar, 0.4kV rooftop solar, small and medium hydroelectricity power generation to the distribution grid of 9 Southern Central and Western Power companies Originally belonging to EVNCPC, EVNSPC increased sharply in the first 5 months of 2021, reaching 5.010 billion kWh. The transmission output of renewable energy sources, medium and small hydroelectricity from the distribution grid, in addition to meeting the load demand of the Power Companies, is also transmitted to the transmission grid at 220kv substations of the Transmission lines. Khanh Hoa, Phu Yen, Binh Dinh, Gia Lai, Dak Lak, Dak Nong, Ninh Thuan, Lam Dong, Binh Thuan in the first 5 months of 2021 are 2.090 billion kWh, which means that the renewable energy output is reversed. to the transmission grid from the distribution grid of the power companies. Thus, the transmission grid under the management of PTC3, in addition to receiving power from the 500kV system and 220kV power plants in the area to supply loads, also receives back-generated output from the distribution grid through the distribution networks. 220kV transformers connected to the national grid cause full load, overload the 220kV grid. This is also one of the reasons for the full load situation for the regional transmission grid, and at the same time brings about the paradox in the operation of PTC3 that the transmission grid managed by PTC3 always operates in a poor condition. state of full load, overload, but the commercial power output did not meet the delivery plan. This shows that there has been an inadequacy when the planned transmission power output is not counted when the renewable energy output is back to the grid. Despite such difficulties, PTC3’s employees are always committed to the power grid and are responsible for their work. They memorized the characteristics of each area of ​​the transmission grid, each compartment of the substation. In the dry season, which columns are at risk of fire due to trees in the corridor. In the rainy season, which pillars are prone to landslide. Which residential areas often fly kites, stretch canvas to dry agricultural products… Just entering the third day of the second heat wave of summer 2021, the national electricity consumption capacity at noon on June 18, 2021, has reached a new peak of 41,709 MW, the PTC3 transmission soldiers are again straining themselves with the harsh climate. of the southern central provinces and the Central Highlands, with the transmission grid always in a state of 100% full load, but not allowing problems due to subjectivity – that is the duty and also the command from the soldier’s heart. Electricity transmission. The current must be kept smoothly despite the unresolved inadequacies, because the story of the mechanism, in order to be removed, still has to be discussed, considered, must be appropriate…and the mission of the transmission soldier is Under any circumstances, the current must be maintained. Because the difficulties that PTC3 is going through is also to test people’s hearts.

From the abode of the poor fisherman Hon Thom is a beautiful island located in the South of Phu Quoc island with an area of ​​about 6km2. With an equivalent area and favored by nature with wild, poetic beauty and beautiful scenery, this “emerging” tropical paradise is likened to Boracay of Vietnam. Hon Thom used to be a poor fishing village, a resting place for ships from all over the world. 10 years ago, Hon Thom was literally a “fish market” filled with all kinds of fishing boats of all sizes anchored to exchange and trade after the trip to sea. The coast is gently sloping, small cruise ships cannot dock close to the shore, so it is rare for a group of tourists to visit for a while. Tourists go to the island early in the morning, swim in the sea, watch the sky and see the mountains, then quickly get on the canoe and board the ship back to the mainland before the afternoon has passed. Hon Thom then looked like a beautiful girl still hiding in the middle of the ocean. On the white sandy shore are small but quite bustling markets, all mainly serving strangers from fishing boats in Ca Mau, Phu Quoc, Rach Gia… anchored outside. The temporary shops set up almost exclusively sell to people taking the train to stop by. Follow the small sandy road lined with coconut trees, about a kilometer long running from the south to the north of the main island where the island’s inhabitants live. Due to the peculiarities of custom, fishing boats often pull together to change places, so the rows of shops or houses are just thatched roofs, sagging wooden houses, it is difficult to find a spacious walled house on the island. This island is about 6km2 wide. The awakening of Hon Thom In 2015, the Phu Quoc district government determined that Hon Thom – the largest island in the An Thoi island cluster would develop in the direction of entertainment and resort tourism. And very quickly, after only a few years, the small island infrastructure completely changed with “terrible” projects invested by Sun Group. If before, the island commune still did not have electricity to the grid, the phone wave was also very unstable, and it was inconvenient to travel to the island, now, thanks to the world’s longest three-wire cable car system, it is less than 15 years old. minutes, visitors will be at the island. Not only the grid is ready to light up day and night, but the wifi is also covered to the cable car cabin. At the end of the cable car in Hon Thom, a vibrant four-season Sun World Hon Thom Nature Park entertainment complex has also been formed, turning the once sleazy “fish market” into a top-class entertainment center on the island. Ngoc Phu Quoc. The performances and festivals are jubilant everywhere, plus the most modern water park in Southeast Asia Aquatopia makes the visitor’s experience seem to be endless. The beaches of Nom, Bai Nam, Bai Chuong, Bai Trao, which were somewhat “wild” and quietly beside the leaning coconut shadows, have now really “awakened” by a series of sea experiences such as jet skiing, paragliding, kayak,… attract tourists to have fun and forget the way home. To the future of luxury residence of the rich The rapid “makeover” of Hon Thom has led to a change in the tourism landscape on the island, tourists no longer focus on the North and Central islands but focus on the South, An Thoi archipelago area, which attracts Number 1 is Hon Thom island. In 2019, Phu Quoc welcomed more than 5.1 million visitors, making the main contribution to Kien Giang’s revenue of nearly 19,000 billion VND, of which the southern island area, notably Hon Thom, also contributed to the number of visitors. small. Along with receiving a huge capital poured into transport and tourism infrastructure, in the near future Hon Thom promises to become the new tourism capital of Phu Quoc. Currently, the rich have begun to “hunt” for the opportunity to find a second home on this paradise island. The attraction of an ideal, fresh and affluent life on a rich tourist island in the middle of the ocean is always the desire of many people, so experts predict that a wave of migration will soon appear. to Hon Thom. It is believed that soon this place will be as busy as Boracay of the Philippines with a busy chain of business shops, high-class resorts by the beaches with potential. The strengths of Hon Thom will be “activated” with unprecedented strength. And the South island in general, Hon Thom in particular will be a lively destination, representing the development of Phu Quoc. Therefore, this is the golden time to own a second home in Hon Thom with a small amount of capital at the early stages of development, before it becomes a highly sought-after property just a few years later on the island. tourist island “earn money”. Thus, you can both enjoy the vacation of your dreams, and at the same time can “pocket” a large profit from rental or self-service travel business. Seize the opportunity soon, creating a prosperous life. Prosperity and prosperity in this place will not take too much time.

Internet capital’s routines have always been based on low prices or even free of charge. The widely-familiar online car-hailing and takeaway industries are all like this. They enclose land at low prices. After they have a monopoly market share, they have increased their prices significantly. Now the price of online car-hailing It is already more expensive than taxis, and the takeaway industry has forced catering businesses to go nowhere, leading to the consequences of bad money driving out good money. A considerable proportion of takeaways directly turn factory-supplied food bags into fast food boxes.

After the capital has gradually harvested many industries, now it has begun to target the last outlet of the middle-aged and elderly-the vegetable vendor. The routine is still so familiar, and it grabs the market at a low price, with the intention of killing the vegetable vendor and waits for the vegetable market. All were forced to close and then raise prices drastically, and this process is still in progress.

For public services such as the power grid, there have been similar cases at home and abroad where capital seized the market and then maliciously increased prices. In the 1990s, Britain promoted privatization and the British gas company was privatized. After the privatization, the British gas company increased its expenses year after year. As a result, the British could not consume fuel. In desperation, they could not turn on the heating in the cold. Cold Bird”.

In the domestic market, foreign capital structures such as Veolia and Suez have successively acquired water supply networks in more than 10 cities. Before the acquisition, they painted a beautiful picture. However, after the acquisition, they did not invest heavily in improving the water supply network. Prices have been raised year after year. In 2014, many cities across the country had odor incidents of tap water, and almost all of the water supply networks in these cities were acquired by foreign capital, which made people rethink the pros and cons of privatizing public services.

Today’s charging services that capital intends to intervene will undoubtedly be similar to previous capital stories. They try to seize the market at low prices or even for free. After occupying the market, they will inevitably increase prices. After all, the ultimate goal of capital is to obtain huge profits. .

However, this time the capital is facing the giant State Grid. State Grid has built the largest charging network in the country, comparable to Sinopec and PetroChina in the era of fuel vehicles. State Grid can quickly build a huge charging network and its own National Grid. It is inseparable as a solid foundation, and this has become its confidence.

As the State Grid has issued a warning to some charging operators, it cannot be ruled out that it will take other measures in the future. After all, with the State Grid as the foundation and power resources in its hands, these vicious competitors will face penalties at any time.

The author supports State Grid’s punishment of these vicious competitors, because it has repeatedly proved that private capital has no bottom line for profit after monopolizing an industry, and State Grid, as a non-private entity, is better able to ensure service quality due to more supervision. And provide reasonable prices.

Internet capital has received a lot of praise for a long time, but as they have achieved monopoly status in multiple industries, the people are disgusted by the people. All parties are becoming more familiar with the behavior of these capitals. There are just a few routines back and forth. I don’t believe in the beautiful vision they portray, but I believe that the ultimate purpose of capital is to make money.

Hoang Hieu Trung, Director of Quang Binh PC said, to ensure stable power supply, the unit will continue to invest in completing the power grid, improving power supply capacity to meet the demand for capacity growth of the load. . The company has also assigned 100% of officers and employees to be on duty, to regularly check the system of transmission lines and substations; mobilize vehicles and machinery to promptly handle incidents in the fastest time. Instructing customers to install the EVNCPC CSKH app to monitor electricity consumption. Due to extreme hot weather, the frequency of using air conditioners, cooling devices, and electronic devices for family activities will be more. This leads to the risk of overloading, power failure, even increased risk of fire and explosion, unsafe operation of the power system. Therefore, in order to save electricity costs effectively and ensure enough electricity for socio-economic development, national defense – security and daily life, production and business of people in the province, PC Quang Binh recommends that customers use electricity safely and economically. Specifically, for businesses, PC Quang Binh recommends balancing and arranging production schedules in the direction of reducing electricity use during peak hours, increasing electricity use during off-peak hours; at the same time, enterprises invest in energy-saving production equipment and coordinate with the Electricity sector to monitor and control power quality. “Hot repair” is one of the solutions to minimize the power outage time of customers in hot weather. In addition, Quang Binh PC requires the electricity companies to actively answer customers about problems in calculating electricity bills, and advise people on how to use electricity economically and efficiently. The affiliated units must well control the index recording and index review to promptly detect and handle abnormal cases, avoiding possible errors. In particular, the Company propagates to customers to use tools and utilities of the electricity industry to actively monitor electricity consumption and control high electricity bills in the hot season such as the EVNCPC Customer Service application on devices. mobile phone or a tool to estimate electricity consumption in daily life for electricity users nationwide at website: https://uoctinhdiennang.evn.com.vn/.

Customers are using the electricity customer management system built by EVNICT. Hoang Dung/BNEWS/VNA Specifically, the Corporation promotes the application of digital technology to innovate and improve the management and operation process of the power system; Design experiences to attract more and more customers to interact on digital channels, enhance analytics to understand customers. The Corporation also improves processes, optimizes corporate governance, enhances governance and data-driven decision-making; Build a digitally savvy, conscious and skilled workforce. At the same time, build a strong and flexible digital ecosystem, maximize shared services and data, and enhance security.

Power planning 8 proposes 3 scenarios for power source development. The Institute of Energy (Ministry of Industry and Trade) has just released a report explaining the conclusions of Deputy Prime Minister Le Van Thanh on the national electricity development plan for the period 2021-2030 with a vision to 2045 (Planning for electricity development). electricity 8). In which, receiving opinions on reviewing the scale of power source development, reasonable power source structure compared to electricity demand in each period, especially in the period to 2030; In order to prevent unreasonable backup of power sources (such as the plan to develop the total installed capacity of 167GW of power sources by 2030, while the load demand is forecast at 86.3GW), the Consultant said Power planning. 8 proposed 3 scenarios for developing power sources to meet 3 scenarios of low load demand, base load and high load. The results of capacity balance of 3 selected scenarios show that renewable energy sources (wind and solar) have the proportion of 24% in 2020; 24-27% in 2030 and 38-42% in 2045 depending on the load scenario. The crude reserve ratio if including wind and solar is always high at 60-80%, but wind and solar power sources are variable renewable energy sources, contributing very little to power system redundancy, especially At the time of maximum load in the evening, there is no sun. Specifically, in the dry season, in the evening, when the national wind power occurs, it only reaches the guaranteed capacity (about 10% of the installed capacity for onshore wind and 20% of the installed capacity for offshore wind). ), at this time, the national crude reserve ratio of power supply will only reach 21% in 2020, 11%-14% in 2030 and 5%-8% in 2045 depending on the load scenario. The consultant said that in order to confirm the redundant or insufficient spare capacity, it is necessary to calculate the expected number of hours that do not meet the load demand. The calculation results show that the reserve scale as above ensures the reliability of the system’s power supply. The proportion of electricity from renewable energy sources (including hydroelectricity) in total electricity production of the selected scenarios all meet the objectives of renewable energy development in Vietnam’s Renewable Energy Development Strategy, reaching 32% in 2030 and 40.3% in 2045. According to the Institute of Energy, although the simulation of energy storage sources has been included, the minimum-cost planning model still chooses to cut a part of renewable energy to meet the flexible needs of the system instead. because investing in more storage resources, because investing in these resources will not be economically viable. The reduction rate calculated from the model is about 1.5% of renewable energy output/year (excluding cuts due to local transmission). The use of a partial reduction in renewable energy to meet flexible demand is used by countries around the world, and accepting a partial reduction in renewable energy is also one of the solutions. to develop renewable energy sources. At the request of ministries, agencies and appraisal councils, Power Master Plan 8 has included additional power source options that occur in addition to the above 3 scenarios to provide information for competent authorities to consider in determining the power supply. operating. In particular, the most difficult option to build power sources and grids is when there are risks of stacking, including high load growth and slow progress of thermal power sources (especially domestic gas exploitation sources). Accordingly, the proposal proposes to select the power source development scenario corresponding to the baseline load demand forecast, which is the selected scenario to calculate the design of the transmission grid, calculate economic and financial criteria. of Power Planning 8. At the same time, the project proposes a power source scenario corresponding to the forecast of high load demand to be considered for use in the management and development of power sources, ensuring to meet demand in the event that the national economy and electricity demand are met. load demand increased dramatically. In case of risk of stacking (high load, slow progress of coal-fired power sources, domestic gas-fired power sources), it will be necessary to add wind power, solar power, flexible power sources, etc. operate ICE to meet the demand for electricity and build more one-way lines from the South Central region to the North to transmit the capacity of power plants.

At the Hai Phong remote control center, the basic features of the SCADA/DMS central software system have been fully exploited such as: managing the grid information model including managing all the main data of the network. control center, edit or create new single-strand diagram structure of TBA, color grid, edit graphics, batch data import, declare and map signals of equipment at TBA and devices on the distribution grid (Recloser/LBS/FI), set up audio and event alarms, simulate the status of equipment on the grid, store, analyze and exploit historical data on the system. In addition, Hai Phong remote control center is gradually deploying and building a smart grid subsystem (DMS) with grid computing applications such as: load reporting, distribution estimation, capacity flow calculation, fault locating and isolation, etc. Operations Engineer at Remote Control Center The conversion of manned 110kV substations into 110kV unmanned substations helps to promote the application of digital technology, innovate and improve the management and operation process of the power system. As of May 27, 2021, the Company has 07/24 110kV substations operating with unmanned criteria, 09/24 110kV substations operating in remote operation mode with on-site supervision. 70/90 devices (Recloser/LBS) on medium voltage grid are connected and controlled remotely from Hai Phong Remote Control Center. With 99% success rate of remote manipulation ( As planned in 2021 put 110kV and . substations control devices Recloser/LBS rest perform remote control) contributed to improving labor productivity, reducing system operating costs, improving reliability of power supply and ensuring safe grid operation. In early 2021, Hai Phong PC applied digital technology to develop software for automatic ground fault handling. The software is currently being put into trial operation. Automatic ground fault handling software is highly applicable, helping to automate the current ground fault handling process, reducing the time to find fault points, and minimizing the number of customers. affected by incidents, thereby reducing power supply reliability indicators SAIDI, SAIFI, MAIFI, improving power quality, avoiding confusion that may occur due to subjective factors of users caused by operation. Automating the troubleshooting process enhances worker productivity by reducing the dependence of the troubleshooting process on the operator. The software is a premise for the development and expansion of advanced applications in the process of modernizing the distribution grid towards operating the smart grid in Hai Phong city. With efforts and determination to realize the goal of digital transformation, Hai Phong PC in particular and the Power industry in general are gradually implementing innovation, creativity, digital technology integration and production management model. business, technical management, making an important contribution to the digital transformation roadmap of the Electricity industry in order to improve the quality of customer service, to meet the needs of socio-economic development of Hai Phong city.

Flight equipment application PTC2 uses drones to manage and operate the transmission grid. Assigned by the National Power Transmission Corporation (EVNNPT) to pilot deploy many scientific and technological applications in the management and operation of the transmission grid, since 2017, PTC2 has researched and applied drones in the field of power transmission. management and operation of the transmission grid. The application helps to reduce the level of burden, improve safety and efficiency, and productivity for workers. Mr. Tran Thanh Phong, Director of PTC2 said that in 2019, after being accepted by EVNNPT, PTC2 has synchronously deployed to all affiliated units to deploy the application of flying equipment in the inspection of the power grid and supporting construction supervision and acceptance of power transmission works. From March 2020 up to now, PTC2 has deployed the application of aircraft to periodically check 1,100 km of 220 kV and 500 kV lines with a total flight time of 29,000 minutes. Thereby, it has contributed to reducing the burden, improving safety, efficiency and productivity for workers such as climbing high, contacting electrical equipment with large electromagnetic fields, moving on difficult terrains. difficult access to dangerous plants and animals. Rapid inspection deployment, being able to access locations in areas divided by rainstorms, landslides, real-time recording of the current situation with good quality images, clear viewing angles to help analyze information more accurate assessment and, most importantly, does not require power line interruption. Mr. Tran Thanh Phong analyzed, when applying flying equipment, according to preliminary calculations, on average, to test 1 km of 500 kV transmission line, it takes 0.52 time to perform the traditional method, and 0. 25 workers, down 0.27 jobs (52.38%). In addition, it also saves a lot of time, costs, and other human resources such as: checking thematically on corridors, conductors, lightning conductors, techniques, insulation status, accessories… Along with that, the application of flying equipment to support construction supervision of power transmission works, inspection, supervision and acceptance of pole erection, inspection of conductors, accessories, route corridors, etc. 220 kV, 500 kV works. Not only that, the application of flying equipment helps closely monitor the technical status of the power grid from above and in places where the human eye cannot see (or is very difficult to see). From there, it contributes to reducing the level of burden, improving safety, efficiency and productivity for workers such as climbing high, contacting electrical equipment with large electromagnetic fields, moving on difficult terrains. , access to dangerous plants and animals. Check for dangerous landslide areas or break off during flooding. Efficiency from surveillance camera system thống Camera system to monitor power transmission lines. An effective application for EVNNPT and PTC2 is the installation of line surveillance camera systems. Realizing the high efficiency and applicability of line cameras, PTC2 has installed cameras at all affiliated Power Transmissions since 2020. Up to now, on the PTC2 grid, 31 CCTV cameras have been installed on the transmission lines of the company. The cameras are connected to the company’s dispatching room so that functional departments as well as company leaders can monitor the current status and direct handling remotely when there are abnormalities on the line. According to Mr. Phong, the camera has a wide field of view, so it helps remote observers to easily detect and accurately assess abnormalities arising on the route such as: fires near the corridor, landslides, vehicles passing photos affect the safe operation of the line. Along with that, the camera helps to quickly access the scene to locations in flooded areas, thereby capturing the situation of the route section and directing appropriate handling. Since installing the camera up to now, PTC2 has detected 35 unusual incidents that may affect the safe operation of the line, thereby taking appropriate measures to ensure operation. In the coming time, PTC2 will continue to research on technology solutions for cameras, solutions for data transmission and analysis, image processing, and propose equipment and installation at necessary and important locations for roads. cord.

Changing habits of saving electricity not only reduces costs for the family but also contributes to saving electricity in general. Although there are not many electrical appliances in the home, only using them in accordance with the needs and reasonable time will contribute to saving a lot of electricity. In addition, customers need to check and maintain the indoor wiring system to ensure reasonable science because if the wiring is confused, it will cause power consumption to be lost in the transmission process; at the same time properly use appliances that consume large electricity such as water heaters, irons, refrigerators, etc. Customer Le Diep Lai in Nguyen Nghiem ward – Quang Ngai city said: “My house has never left the air conditioner below 25 degrees, usually around 26-27 degrees. I find that to be appropriate, not much different from the outside, both protecting health and saving electricity. I also educate my children to turn off electrical appliances in the house when they do not need to use them. Vu Ha Ty customer in Nghia Dung commune – Quang Ngai city only uses the air conditioner when absolutely necessary and usually adjusts the temperature not too low to save energy. Ms. Ty shared: “My house is not located in the center, there are many gaps around, so I often use the wind and natural light in the house, minimizing the use of electricity to operate the cooling equipment. lighting”. Changing the habit of using electricity will save electricity, reduce costs for the family and contribute to saving electricity in general. Although there are not many electrical appliances in the home, only using them in accordance with the needs and reasonable time will contribute to saving a lot of electricity. Currently, customers can use the monthly electricity consumption estimator https://uoctinhdiennang.evn.com.vn to calculate the monthly electricity consumption of the family, thereby adjusting the usage. Use electricity in the most efficient and economical way. Propagate the use of electricity to the people. Huynh Trong Nguyen – Quang Ngai PC Business City recommended: “In addition to daily-life customers, manufacturing enterprises need to review and arrange reasonable production plans, minimizing the simultaneous mobilization of devices. consume large electricity capacity during peak hours and do not leave electrical equipment idle. This is the necessary coordination to ensure the stability of the infrastructure, and to ensure the supply of electricity for production and daily life in the dry season of 2021.”
In addition, to prevent local overload due to high demand for electricity, from the beginning of the second quarter of 2021, PC Quang Ngai also directed its affiliated units to regularly check lines and substations. Thanks to the initiative in the plan and the use of modern equipment such as thermal cameras, flycams, Quang Ngai PC was able to immediately detect and detect abnormal signs occurring with the equipment, preventing problems. can happen.
The economical and efficient use of electricity by customers is also one of the important solutions to help Quang Ngai PCs fight overload, reduce “heat” for the power grid system; thereby contributing to helping PC Quang Ngai perform well the management and operation of the power grid safely and effectively, improving the quality of power supply for customers.

The remote operation success rate is over 99%. When an incident occurred, 81% of affected customers were immediately transferred and restored to power in less than 5 minutes (compared to 120 minutes of TCT’s regulation). The process of investment in development and modernization of the power system in Thu Duc City over the past years has shown that the reliability of power supply has improved significantly. Average number of outages per customer (SAIFI) is 1 time/year; the average outage time of a customer (SAIDI) is about 60 minutes/year – much lower than the 2015 index of 6 times/year and 700 minutes/year, respectively. With the motto “Electricity is one step ahead”, Ho Chi Minh City Electricity Corporation has a plan to prioritize investment in the development of the power system for Thu Duc City, focusing on developing smart grids in parallel with deploying other utilities. underground works. The goal is that by 2025, the electricity output supplied to the people of Thu Duc City will reach 5,500-6,500 kWh/person/year, the average number of power outages is less than 0.3 times/person/year and the average duration of power failure. less than 30 minutes/person/year. Mr. Pham Quoc Bao, Chairman of the Members’ Council of Ho Chi Minh City Electricity Corporation. In the period of 2021-2025, Ho Chi Minh City Electricity Corporation will invest about VND 3,200 billion to build a new 220 kV station and 6 110 kV stations (total added capacity is 1,382 MVA), develop 245 new stations km of medium voltage grid; 585 km of low voltage power grid, renovating and installing 447 distribution substations with a total capacity of 363 MVA in Thu Duc city. In this year, the corporation will complete Phuoc Long 110 kV station, start construction of new 110 kV Linh Dong station, 220/110 kV Thu Thiem station and 110 kV Thu Thiem station 1. In addition, the Ho Chi Minh City Electricity Corporation deployed 27 projects to undergroundize the power grid combined with information lines in Thu Duc city, in order to increase the undergroundization rate of the medium voltage grid from less than 50% at present to 75. -80% by 2025. With the motto “Customer is the center”, the electricity industry promotes digital transformation to improve the quality of electricity supply and customer service for the whole Ho Chi Minh City, including Thu Duc City. The focus is on promoting digital transformation in power system operation management and customer service provision in Ho Chi Minh City. The Corporation promotes the development of smart grids in Thu Duc city with the investment of a remote metering system, increasing automatic components on the power grid. Currently, the Corporation has basically completed the installation of distance meters in Thu Duc city. By the end of this year, 100% of medium voltage lines in Thu Duc city will operate fully automatically (DAS/DMS). In the period of 2021-2025, the corporation will continue to invest in strengthening remote control devices for medium voltage lines, along with solutions to close loops, and enhance the form of construction without power cut (live- line), in order to improve the flexibility of transmission, reduce the range and number of customers affected by power outages (if any). View of Thu Duc city. On the other hand, the corporation promotes the development of EVNHCMC Customer Care application (app) on the phone. The area of ​​Thu Duc district (old) has completed the installation of distance meters since 2020. Customers can monitor their daily electricity consumption through this application. All electrical services are provided online by the corporation. Customers do not have to go to the electricity headquarters to register, instead register for the service on the customer care website or via the app) EVNHCMC Customer Service of the corporation. In addition, TCT also promotes the application of 4.0 technology in surveying, designing and improving procedures to continue to improve the electricity access index, ensuring all investment projects through the medium voltage grid. 22 kV power supply for customers is carried out by the electricity industry within 5 days, contributing to attracting investment businesses in the city. “EVNHCMC prioritizes focusing resources, rapidly developing modern power systems in Thu Duc city, in order to ensure the power supply capacity to meet the city’s development needs, constantly improving the quality of electricity. electricity and customer service, contributing to building Thu Duc City into a new growth pole of Ho Chi Minh City, worthy of its potential and meeting the expectations of leaders and people”, Mr. Pham Quoc Bao positive.

Power lines connecting high-voltage poles near the capital Brasilia (Brazil). Photo: Reuters. According to ONS General Manager Luiz Carlos Ciocchi, this could lead to higher electricity prices. However, the situation is still positive when the risk of power shortage or interruption of distribution has not yet occurred. About three-quarters of Brazil’s electricity is generated from hydroelectric plants. This is one of the largest percentages compared to countries in the world. Brazilian President Jair Bolsonaro said on May 10 that the country was experiencing the worst water crisis in its history, and warned of major problems with electricity production. The crisis comes at a time of increased demand for energy, as temperatures rise in the coming summer months. Last week, Brazil’s Electricity Supervision Commission approved potential additional measures to meet electricity demand, including increasing the power output of thermal power plants and importing energy from Argentina and Uruguay. Mr. L.Ciocchi said that the government should reserve water in the lakes to meet the needs of the people and maintain the necessary hydropower output.

In order to improve the quality of electricity supply and reduce the time of customers’ power cuts, especially in the approaching hot season, in addition to 04 hotline insulation cleaning teams, they perform the task of cleaning electrical insulators with pressurized water. On March 10, 2021, Ha Tinh PC established a hot line repair team on the 22kV power grid that is carrying power (belonging to the Ha Tinh high voltage grid operation management team). The team is responsible for managing vehicles and equipment and implementing plans for repair, maintenance, replacement and connection of equipment on the 22kV live grid. The members of the team have been well trained, and invested in modern and advanced equipment, tools and instruments. After nearly 02 months of operation, the team has carried out nearly 70 sessions of hot repair work, including the following work contents: Separation of connections; poor breaker contact handling; replace lightning protection valve; new installation of load circuit breakers; replacing the shaped porcelain neck ties to prevent surface discharge and handling defects in bows and legs … have been done by the hotline repair team in the past time. In order to operate effectively, before that, the team was sent by the Company to study the construction and repair of hot line electricity at the Northern Electricity College; Trained and tested to meet the requirements of theory and practice on live lines at the hotline field, then continued testing on the 22kV power grid of Ha Tinh PC. Through training and practical tests, team members are not only strong in their expertise and techniques, but also create a stable and calm mentality for members, improve their sense of discipline, and strictly follow them. regulations and procedures for occupational safety. Workers of Ha Tinh PC hotline team perform operations on a live grid Mr. Nguyen Van Nhu – Team leader of the hotline said: “When switching to hotline work, at first, the brothers in the group were still confused. However, through the process of being trained and trained, and timely grasping new techniques, up to now, the team members have mastered the technology when accessing the power grid. During the construction process, members always have a sense of reminding and monitoring each other, absolutely no redundant movements to ensure absolute safety when performing tasks. According to Mr. Nhu, in the past, even a small problem had to be cut off to fix it, but when applying new technology, customers can still use electricity normally, daily activities, production and business. business is not interrupted. It can be seen that the application of hotline repair technology into operation has brought many practical benefits, the work contents on the grid have been shortened, helping to save time, prevent and minimize incidents on the network. electricity grid, reducing power loss, contributing to increasing labor productivity, improving the reliability of power supply to meet the increasing demand for electricity of customers.

In order to prepare for the heat wave in 2021, Nghe An Power Company (Nghe An PC) has directed its units to quickly deploy the proposed solutions and scenarios to ensure electricity supply for the whole country. Nghe An province. Nghe An PC workers check outdoor equipment at Hung Hoa Substation (Nghe An) PC Nghe An information, during this year’s hot season in Nghe An, there will be many prolonged heat waves, leading to an increase in the demand for electricity for cooling than in previous years. It is expected that power output will increase, with an estimated capacity of about 820 MW. In order to ensure stable power supply in the face of increasing electricity demand in the summer of 2021, Nghe An PC has prepared a “scenario” carefully, with many solutions to supply electricity to people and businesses. Mr. Le Quang Thanh – Deputy Director of PC Nghe An said that 2021 is not expected to be as hot as the previous year, but despite the prolonged epidemic, most businesses in the area are operating stably again. power consumption is expected to increase. Regarding the load forecast, this year’s output growth will be higher than last year’s at over 12%. The most important and basic solution identified by the unit is to increase the power supply capacity, with the rapid completion of construction of substations and power lines for areas in the province. Accordingly, from the end of 2020 until now, Nghe An PC has built and installed hundreds of large and small projects, including: Raising the capacity of 110kV substation in Cua Lo route, increasing the capacity of 110kV Quynh Luu substation, completing upgrading the transmission line. 110kV from Quynh Luu – Quy Hop. Along with that, renovating and upgrading low-voltage trunk roads; replace the meter periodically; strengthening overhaul, cleaning of transmission lines and transformers; replacing the name plate number of the road, pole number, safety sign of the substation transmission line… and is implementing the plan to energize and put into operation 110kV Con Cuong substation, increasing the capacity of 110kV Hung Nguyen and Quy Hop substations in the month. 6/2021. After energizing, the station will power on in time to serve the people’s demand for electricity in the summer months; support stable and safe power supply in the area. However, according to PC Nghe An, the case of an unexpected increase in output through monitoring is unlikely and in fact, if it happens, the power infrastructure including medium voltage transmission lines, substations and power grids. low voltage will still be able to meet. Alternating power cuts to reduce capacity as announced by EVN will not happen, however, it does not exclude some cases such as: The power supply of the whole system is malfunctioning, incidents such as the breakdown of hydroelectric power units , the North – South 500kV transmission fault leading to failure to mobilize the grid capacity of the whole system will be automatically laid off. In addition, there is a problem of maintenance schedules of power plants (thermal power plants, hydroelectric plants) which can also lead to lack of power, requiring capacity regulation between regions. In the coming period, the vicinity of Nghe An will record a sudden increase in load, especially in Thanh Hoa area, and in Nghe An will also have a sudden increase at the end of 2021 when Hoang Mai 1 and Hoang Mai IPs WHA Industrial Park comes into operation. This is not only a problem for the electricity industry in Nghe An but also for the power system in the North as well as in the whole country. To solve it, EVN will have capacity coordination solutions to meet demand. Power supply scenarios have been developed at the transmission grid level (220kV, 500kV) in order to mobilize and balance capacity in the North – Central – South region. Thus, in the short term, the stable and continuous power supply for Nghe An will be ensured. PC Attention Nghe An Use electricity in hot weather PC Nghe An also noted that, in order for the power grid to operate stably during the peak of heat, it is necessary to coordinate and propagate propaganda at all levels of the government, local and central media agencies on the appropriate use of content. , saving. This content is very important for the national power system and grid, will avoid unnecessary grid overload due to unreasonable use, reduce the greenhouse effect, help limit environmental pollution, have a enough electricity to serve economic development for production and also save living costs for electricity users themselves. PC Nghe An continuously advises customers to avoid being subjective, negligent, not to misunderstand between electricity price and electricity consumption; Use electricity in the most efficient and economical way when entering the hot season. Just small actions from the people such as turning off electrical appliances when not in use, not using many large-capacity devices at the same time, using low-power consumption equipment labeled energy-saving by the Ministry of Industry and Trade. Industry and Trade inspection will help save electricity. PC Nghe An has prepared scenarios for electricity growth in hot weather Families should use air conditioners at a reasonable level of 26-27 degrees Celsius or higher and use fans in combination to reduce power consumption. When using a cold room, do not open the door often, do not use electrical appliances with heat-generating features in the room such as irons, ovens, electric kettles, and hot water heaters. Families have many rooms, when watching TV should focus on watching together, turn off all devices in neighboring rooms. Use electricity only when absolutely necessary, avoid using devices simultaneously during peak hours… For factories, make sure to use the correct capacity and load chart. Along with that, implementing a reasonable production plan, minimizing the mobilization of equipment and machinery with large electricity consumption capacity at peak hours. To minimize electrical equipment operating at no-load, key energy-using establishments must save at least 2% of electricity consumed per product unit per year. Advise customers to use electricity as committed to the electricity industry in terms of registered load and time frame, or reduce capacity when required by the electricity industry due to sudden increase in load… When purchasing new equipment, pay attention to use equipment with energy-saving certification label of the Ministry of Industry and Trade. Responding to the electricity sector, coordinating propaganda and recommending surrounding households to save together.

This time started in the summer, the demand for cooling devices increased, leading to a dizzying increase in electricity bills, so solar fan models were sold on the market. They are advertised, instead of running on electricity like conventional types, this type of fan operates entirely on solar power. Specifically, each solar fan will come with a solar panel to help absorb sunlight and produce electricity to maintain operation. Depending on the type of panel, when placed in the sun, the fan controller will charge the battery, which takes 4-6 hours. After the battery is fully charged, the fan will work for 6-10 hours continuously, even on rainy days without sunshine. In addition, users can use grid electricity to charge the battery for storage and use. Solar fans are causing fever in the market this summer Currently, on the market, these fans come from many places such as: China, Korea, Vietnam, … with very diverse prices, depending on size and function. In which, the lowest price is about 200,000-300,000 VND (mini fan), tree fan costs 800,000-2 million VND. Many fan lines are being discounted by 20-50% to attract buyers. For example, the 20W mini solar fan line is being discounted by up to 50%, from VND 830,000 to VND 417,000; mini fan 3.5W X9E is 40% off, from 510,000 VND to 306,000 VND; The Sunisi FT-30 fan model is priced at 1 million VND, 50% less than the original price of 2.1 million VND; Korichi KRC 6300 fan model reduced from 1.2 million VND to 890,000 VND; Jenpect 220V fan model has the original price of 1.3 million VND, down 34%, now only 850,000 VND,… According to the advertisement of the staff of household electrical stores, compared to traditional fans, solar fans have many advantages such as: no electricity costs, no fear of sudden power outages in hot summer days. Not only that, they are also very convenient when going on a picnic or camping trip; can directly charge other mobile devices such as phones, flashlights, … via USB port, which is very convenient. Moreover, long battery life 3-5 years of use, battery capacity up to 12,000 mAh, using time up to 8-12 hours. With “divine” functions, especially without consuming electricity, this type of solar fan immediately caused a fever in the market and was sought after by many people. Mr. Nguyen Hung – an employee of an electronics store in Ho Chi Minh City – said that at this point, the demand for cooling fans has begun to increase sharply, in which the solar fan line is the best-selling model. . As at the beginning of summer, his shop sold about 300 solar fans, at the peak of last year’s heat, he sold up to 800 units. Many fan models are having super cheap prices to attract buyers Similarly, Mr. Hoang Van Binh – an employee of an electrical appliance store in Thanh Xuan (Hanoi) – also said that in recent years, the price of electricity has tended to increase, people have the need to buy and use electricity. Use energy-saving appliances and take advantage of natural energy sources. Therefore, from May, customers looking to buy solar fans are busier. Currently, he only has 15 more fans to sell out. According to him, this type of fan is often suitable for low-rise houses, level 4 houses rather than high-rise buildings and apartments like in the city. Because the fan and solar panels are separate, it is necessary to choose a location to mount the panels to catch the sun (roof, rooftop, balcony, front yard, …) then connect to the fan set. Therefore, with high-rise buildings, moving equipment is quite difficult. But Binh also admitted, when it rains, the charging capacity of the fan will be poor, so in the prolonged rainy season solar fans will not be able to promote their full benefits. At that time, the fan can still be used by the grid as usual. Talk to PV. VietNamNet, Mr. Le Van Kien – a technical staff member of an electrical appliance store in Khuat Duy Tien (Thanh Xuan, Hanoi) – shared, when buying a solar fan, it is necessary to pay attention to the lifespan of the panels. The origin of the battery is unclear, poor quality will make the fan’s performance worse, the fan runs erratically, the lifespan is reduced, and it pollutes the environment. Moreover, the life of the battery is usually only 2-3 years, then it has to be replaced at a considerable cost. In addition, the capacity of the battery will determine the operating time of the fan, the battery is designed with a high capacity, the better the charge will be and vice versa. Limit the selection of multi-function rechargeable fans that are equipped with lights, alarms or clocks… because these features consume power from large batteries, making it easier for the battery to fail faster. Users should not be greedy, but buying low-quality fans will have many potential risks, so consider when choosing and need to choose to buy products of reputable brands and addresses.

In particular, thanks to the opening of the road along Lap An lagoon, many eco-tourism sites in the area were discovered and exploited, contributing to creating jobs and improving the lives of many households. in the area. And Do Waterfall in Bald Coconut is one of the eco-tourist destinations that in our opinion you should come to experience this summer. If you depart from Hue, follow Highway 1A to Phu Loc, cross 2 passes Phuoc Tuong, Phu Gia, look to the right, you will see a wide lagoon with a soft winding road bordered by a picturesque landscape. drawing – That is the lagoon and the road along Lap An. You can choose to turn right from the foot of Phu Gia pass, or continue to go straight towards Lang Co town and turn in, leisurely follow this road for a few more kilometers, to the territory of Bald Dua village, you will see a signpost. ; Or simply ask the locals, anyone can show you the right way. Clear water for guests to enjoy swimming and bathing The road to Thac Do is very easy to go, low-rise 4-seater cars can also come to the place. The waterfall originates from the top of Bach Ma mountain, when it rumbles, when it travels through the green primeval forest canopy of the National Forest, to Bald Coconut, the water poured over many years has created 3 successive lakes. connected, transparent. Each lake is about a hundred square meters wide, enough for visitors to enjoy bathing and swimming. At the bottom of the lake, which is not too deep, there are many small stream fish swimming, working hard to find moss to eat, or hiding in the rock holes that make the children love to dive and catch them tirelessly. From the lakes, guests can go upstream, just a short distance to check-in, cool off with pure white water. Those who want more can find a certain niche, sit with their backs to the massage water comfortably without having to be afraid of charging fees and calculating “tips”. Of course, care must be taken to avoid locations with a lot of moss to avoid dangerous falls. Eating and drinking, shacks are served by local people, simple and reasonable prices. The food is fresh and delicious, but in general, the scenery is so fresh and beautiful, everything feels delicious. In the first years, go to the place to find the shack before ordering. Later on, tourists heard the voice coming back a lot, the service was also “pro” gradually, there was a Fb page, there was a phone number for customers to book in advance. I just hope that the business people here know how to respect and preserve the landscape, which is also preserving their source of life. Must raise awareness of environmental protection, awareness of preserving beautiful views for the lake and waterfall. Avoid the situation where everyone does, strong everyone wins, leading to damage to the destination, tourists turning away is a waste and a waste. Sunny days have sounded very acrid. Get in the car, Thac Do is on duty. You will surely be satisfied. https://dulich.petrotimes.vn/

The company has automated the voltage and frequency adjustment of the power system to ensure power quality; Reducing the amount of electricity that cannot be supplied to customers, creating more revenue for the electricity industry; Reduce long distance transmission and optimize transmission grid loss. Modernizing the development of electricity meters and remote metering data collection systems has helped to collect complete data on customers’ electricity usage, timely detect problems of the metering system. count. This technology also helps the Company closely monitor the electricity usage mode of customers, especially large customers, and at the same time serve to calculate the unit’s power loss accurately as well as the power loss of the station. public in particular. In addition, the Company also encourages customers to actively adjust or change electricity demand during peak hours. Thereby, reducing the maximum capacity of the power system, reducing the overload of the grid, contributing to improving the economic efficiency of the power system. At the same time, it will also create conditions for the community to be more aware of electricity saving and efficient use of electricity, contributing to the protection of national resources. Ba Ria – Vung Tau Power Company has implemented many measures to reduce power loss With the unremitting efforts of all employees Ba Ria-Vung Tau Power Company in the control of power loss in particular, the rate of power loss continuously decreased from 2015 to 3.97% at 22kV level; in 2019 is 1.75% (including 110kV level) and in 2020 is an impressive number: 1.57% (including 110kV level). With the mission “ Electricity is one step ahead ”, BRVT Power Company has actively invested and upgraded the power grid system, ensuring safe and reliable power supply for tourist centers such as Thuy Van beach (Vung Tau City), Long Hai beach. (Dat Do district), Ho Coc – Ho Tram resort (Xuyen Moc district)… Every year, the Company focuses its capital to invest in preventing overload and strengthening the power grid; Electric islands for industrial shrimp farming, irrigation pumping stations to fight against drought, concave areas without electricity, removing fishing tackle… to meet the demand for irrigation for agricultural production and aquaculture. fisheries and tourism development in the province. Doing a good job of reducing power loss makes a lot of sense. help reduce production costs, increase profits for the company and increase the efficiency of production and business of the unit.

Mr. Chin’s family also has a long tradition of fishing. Initially, every day with boat cruises filled with fish. So I did not eat all, and added Co To many years ago, there was no electricity to the net, so almost every family with a fishing job would have a job of making fish sauce, because that would only be able to handle the amount of fish. Rice … a lot of redundancy after each trip out to sea. Mr. Le Van Chin has worked as a fish sauce for several decades. Mr. Chin said, this profession ranged from selecting fish, making the best fish sauce which is anchovy, to the stage of brewing and distilling according to a process. Although there is a general recipe, but the workers also need a certain experience, so the same ingredients, the same recipe tools for fish sauce are the same, but some people produce delicious fish sauce products, others do not. The fish sauce factories in Co To all use ceramic jars to make fish sauce, not cement tanks, to ensure that the fish sauce in the jars is kept intact, because the fish sauce has salt, and other materials are soaked for a long time. corrosive but not in jars. When finished a batch of fish sauce, jars are cleaned and sanitized, then dried to kill bacteria before preparing a new batch of fish sauce. To make fish sauce delicious, Mr. Chin is very careful from the import of ingredients. He contracts with fishing vessels, purchasing as soon as anchovies are imported into the port early in the morning. Being a fisherman, he chooses anchovies that are fresh, bright and not damaged. Because the fish sauce must be marinated every year to be used, Mr. Chin actively imports fish at the coldest time of the year from November of the previous year to March of the following year. This is the time when anchovies are abundant, fatty, of good quality. On the other hand, due to the cold climate, fish are also best preserved. Co To anchovies are rich in protein, preliminary processing, marinated with a certain percentage of salt in the jars, Mr. Chin carefully reverses every day in the sunlight, repeating every day from 12 to 15 months. At that time, the fish can gobble up enough to produce fish sauce products. Mr. Chin said, even keeping fish in jars requires a certain experience, it is best to choose the best sunny days, not to dry on bad weather days with rain, because it only needs a few drops of rain. also ruined the jar of fish sauce. Now that the age is high, Mr. Chin only works moderately, he produces about 700 liters of fish sauce annually. His family’s fish sauce products have a reputation among the islanders, and many tourists also order them. Co To has an abundant source of raw materials to produce fish sauce. In recent years, Co To district has stepped up vocational training for people, many families have learned to do fish sauce. Ms. Phan Thi Tuyet, Hai Tien village, Dong Tien commune, after attending a seafood processing class taught by staff of the Department of Labor, War Invalids and Social Affairs since 2015. Having a job, Tuyet and her husband arrested her. Right hand on making fish sauce. Initially, Ms. Tuyet only made a few jars to eat gradually, then introduced it to the neighbors. Seeing that everyone praised the deliciousness, so Tuyet boldly borrowed to buy 36 jars to make fish sauce and annually produced about 3,000 liters. Co To fish sauce makers are self-conscious about food safety and hygiene to make fish sauce, that is why Co To fish sauce is a prestigious OCOP product for many tourists from near and far. When coming to Co To, when returning home, many tourists do not forget to bring back a few liters to tens of liters of fish sauce to make gifts for their family members. Even when they got home, they still contacted the Co To fish sauce maker to send the goods to them.

EVNCPC strengthens the inspection and repair of the power grid to ensure that customers do not cut off electricity during the holidays of April 30 and May 1 this year. (Photo: Tel). Mr. Nguyen Thanh – Deputy General Director of EVNCPC said that on the occasion of April 30 and May 1 this year, employees are entitled to 4 days off, so EVNCPC forecasts the demand for electricity for domestic activities and public holidays. This will also increase.

7:00 am, we arrived at Cai Rong port (Van Don district), boarded a modern 2-hull boat straight to Co To. Only 65 minutes later, the ship cut off the waves to dock on the island. An area of ​​pearl island with white sand and blue sea, spacious roads make people feel like a corner of Nha Trang or Phu Quoc. Few people know that this place used to be a difficult area lacking hundreds of faces, even fresh water is also a luxury. The turning point came in 2013, the leaders of Quang Ninh province were determined to pull the power grid to the island, although the resources and technology were still limited at that time. Along with that is the construction of fresh water reservoirs. Having electricity and water has helped Co To’s economy “brighten”, people’s lives have been rapidly improved. Co To rose to become an attractive destination for tourists. ‘Bringing electricity to Co To island is strategic thinking’ Mr. Le Hung Son, Secretary of the District Party Committee, Chairman of the People’s Committee of Co To district assessed that the project of bringing electricity to Co To island in 2013 was a great turning point, helping this island district to have great development. Co To is a pre-pepper island district of the country with 200 km of sea border stretching from Tran Island to Bach Long Vi archipelago of Hai Phong. The district has 50 islands, large and small, of which the largest is Co To island, about 50 km2 wide. The primeval forest here is preserved almost intact with hundreds of years old trees, tangled vines. Co To also owns 300 km2 of fishing grounds. The potential is that, but before 2010, the economy in Co To is almost underdeveloped due to limited infrastructure, especially the 3 shortages: lack of electricity, lack of fresh water and lack of ships to the island. Only over 50 nautical miles from Cai Rong and Van Don ports (more than 60 km), but in 2011, Co To was still very far away because only 2 wooden ships traveled for more than 3 hours to arrive. There is a lack of electricity on the island, especially fresh water in the dry season, so all services and tourism cannot be developed. Mr. Dao Van Vu, now Vice Chairman of the People’s Committee of Van Don district, who had more than 20 years of attachment to Co To, recalled the difficulties on the island: “There were times when I started from Cai Rong, but only 6 hours later to arrive. Because of the strong wind, the train had to go around to avoid the waves. When coming ashore, they must carry sandals, roll up their pants and wade ashore but do not have a wharf. The district has no grid electricity, the main source of electricity is 2 diesel-powered engines. One day only power supply until 20-21h is to be cut off. Because electricity is powered by generators, the cost is very high, 5,000-6,000 VND / kWh, homes using a lot of high stairs can reach 15,000-16,000 VND / kWh. Most houses only use electricity for lighting and fans for essential needs. The tourism industry is less developed due to difficult travel and modest accommodation conditions. There are almost no hotels in the whole district, mainly small motels. Even if guests want to use the air conditioner, they have to pay extra electricity with very expensive prices. There is only one old police force on the big island. Therefore, traveling and transporting passengers and goods is very difficult. In 2010, Co To welcomed less than 5,000 guests. By 2011-2012, although the engine was more equipped and had a larger capacity, the guests only reached about 30,000 visitors. Also because there is no electricity, the seafood caught on the sea is difficult to preserve, many fishermen have to sell directly at sea to the merchant boats from the mainland to buy at low prices, because bringing back to the island is also difficult to preserve. and there is no electricity for processing. In addition to lack of electricity, Co To also lacks fresh water. During the dry season, families have to divide each barrel of water. Mr. Nguyen Duc Thanh, former Secretary of Co To island district in the period of 2010-2015, recalled: “When I went to the island to take office as the island district’s secretary and president, I and the district leaders also struggled to find solutions to overcome the power shortage. lack of water, lack of boats for people on the island, but until 2011 it is only possible to start the construction of freshwater reservoirs, while pulling electricity is too far away, never can do it ”. With that same lake, Mr. Thanh used to sign a “military status order” with the Secretary of the Provincial Party Committee: “In August 2011, just a few days after he took office as Secretary of the Quang Ninh Provincial Party Committee, Mr. Pham Minh Chinh made a visit. Unofficially went to Co To money island district. Myself and a comrade drove the new Secretary to visit the island on the only pickup truck borrowed from the district police. When he saw that we were building the Truong Xuan freshwater lake, he asked how long the project would take, I said it took 3 years because of lack of capital. Then the Secretary asked: If the province prioritizes to allocate capital, can you do it in 1 year, do it quickly but must ensure the quality? I confirmed that I could do it, the Secretary immediately asked to write the commitment, I made 2 copies, 1 copy sent to the Provincial Party Committee and one sent to the Provincial People’s Committee. After supplementing capital and mobilizing labor, mechanical equipment, we put the lake into operation on time as committed, still operating well, is the largest source of fresh water on the island ”. Regarding electricity, Mr. Thanh said, at that time he reported to the Secretary the optimal plan is to pull cables, but with difficulties in technology and capital; If we make coal-fired power, we cannot develop tourism because it will be polluted for the whole island. “At that time, the Secretary did not make any decisions, we did not know if we could pull the cable to the island, because there has never been such a long submarine cable project in Vietnam,” said Thanh. A few weeks after the new Secretary of the Provincial Party Committee’s visit to Co To, Mr. Thanh was summoned to attend a meeting of Quang Ninh leadership chaired by Pham Minh Chinh Provincial Party Secretary, where a decision made 5,000 people. Co To island district is very happy: Pulling electricity by underground cable to the island. Mr. Thanh said at that time, the head of the party committee of Quang Ninh province told him: “We try to bring electricity to the island, to build a reservoir to take care of water for the people, then the enterprise will invest in a modern fleet. connect the island to the shore “. So, the three difficult things of Co To have been solved. Technically, to pull the grid to the island is a big challenge as the longest underground cable distance is 25 km (between island and island). Technology to pull electrical cables under the seabed was very new and almost nonexistent in Vietnam. To bury the cable, the engineering unit must use a robot to cut the rock, dig the surface of the seabed to a depth of about 1.5-2 m, then the divers lower the cable to the newly dug slot, then place a solid material. special coating to protect the underground cable bundle. Many people are skeptical about the safety and feasibility of towing the cable under the sea. Another problem is the huge cost of capital to pull out electricity, up to more than 1,000 billion dong. In 2011, the budget for development investment of the whole Quang Ninh was only about 6,000 billion VND, not too much for such a large project. The Northern Power Company cannot afford to do a big project, while the immediate business efficiency is not high. “There were many difficulties, but the Secretary and the Standing Committee of the Provincial Party Committee at that time were determined to pull the power grid to the island. The difficulties in both finance and technology have been gradually removed with a drastic, urgent and detailed participation ”, recalled Mr. Nguyen Duc Thanh. Project scale includes more than 27.5 km of 2-circuit 110 kV transmission line; 22 km of 22 kV overhead transmission line; 23 km of underground cable line; 8 cutting stations 22 kV; 12 substations and 34 km of low voltage transmission lines. The 100 kV line sections are wired by a hot air balloon, while the average depth of the seabed to lower the underground cable is 29 m. At that time, the leaders of Quang Ninh province had a valuable decision to include fiber-optic Internet in the bundle of electrical cables, so now Co To has both grid electricity and broadband optical fiber lines. The project’s estimate is about VND 1,100 billion, of which the Northern Power Corporation will contribute VND 350 billion. The remaining amount in Quang Ninh is about 830 billion, mobilized by socialization and the provincial budget. Many Quang Ninh people cannot forget a very exciting and meaningful campaign to contribute: Contribute to the people to pull electricity out to Co To. Each civil servant in the whole province contributes 1 day of his salary. The province also calls on people, businesses, social organizations, even people from Quang Ninh who are far away from their hometown to contribute. The remainder is taken from the provincial budget. After 350 days of construction, in October 2013, the project of pulling the grid to Co To by underground cable was completed before the overwhelming joy of the people of Co To and the whole province of Quang Ninh. Many old people on the island shed tears when they see the light from the national grid on the island. Young people radiant eyes look at computer screens, phones with high-speed Internet connection, merging with the global flow of information. Along with electricity, Truong Xuan lake with a capacity of 170,000 m2 together with Lake C4, Ong Thanh, Ong Cu … is a strategic source of fresh water for Co To island district. Thus, in just a few years, Co To had both electricity from the grid, fresh water, an unprecedented change in this front-end island. Every morning, Co To wharf is busy with dozens of tram cars waiting to welcome guests, see off guests, and carry goods from ships connecting to the mainland. Mr. Nguyen Van Hung, owner of a 2-star hotel near the wharf, recalled that eight years ago, when Co To did not have electricity, he never dreamed that he could do it like today. After Co To got electricity, Hung finished building a small motel. The number of visitors to the island increased sharply this year and a half years ago, making his motel continuously expand. Anh Hung is now the owner of a 2-star hotel with nearly 60 rooms, a few more electric cars to pick up guests. Mr. Nguyen Toan, manager of Tuan Vu Hotel on Co To Island recalled in 2013, when the owners on the mainland poured hundreds of billions to build a 3-star hotel on the island, many relatives and friends were discouraged. and said “crazy”. Someone said Co To at that time was both difficult and difficult to come by. When we invested so much money, we knew when we could recover our capital. However, with the love of the sea and islands and seeing the potential for development, the owner is still determined with his plan. And the sweet fruit has come to the summer tourism season in 2014. The hotel is always in a full room with many large groups of guests. The investor initially expected 12-15 years to break even, but so far has been able to recover the capital in 8-9 years. Since the electricity came on, the number of visitors to Co To skyrocketed. From 35,000 turns in 2012, in 2019 (before the translation of Covid-19), Co To received nearly 300,000 visitors, nearly 10 times higher than before. When electricity is available, many people also have conditions to invest in accommodation, food, and services to provide tourists. On the contrary, as the service develops, more tourists come to Co To. Currently, traveling from the mainland to Co To is very convenient with many trains going and arriving during the day. There was even a 5-star standard train running the Cai Rong – Co To route which traveled less than 60 minutes, can be used in the wind situation of level 7, carrying 850 passengers / trip at the same time. On the island, there are 300 electric cars to serve tourists, nearly 200 accommodation establishments, nearly 2,500 rooms, 51 homestays … Up to now, Co To can welcome 10,000 tourists at the same time. Tourism revenue from 50 billion in 2013 to reach 700 billion in 2019. With electricity and water available, the processing industry also developed. People can invest in means, catch seafood and then return to deep processing on the spot to sell at high prices. The Secretary of the District Party Committee, Chairman of District People’s Committee Co To Le Hung Son said that the most important thing when having electricity and water is to help improve people’s lives in all aspects, the economy can achieve important developments. The average income of Co To people reached 4,500 USD / year, higher than the national average of more than 1,000 USD. “Improving people’s lives and economic development is also a measure to maintain security and national defense in the country’s pre-emptive and anti-dumping islands,” said Mr. Son. Mr. Thanh said that the success of Co To today is a clear proof to see the vision and determination of the provincial leaders before. Mr. Le Hung Son said that in the future, Co To strives to become stronger, and welcomes 1.6 million visitors by 2030. The island will also focus on attracting large investors, bringing tourism to development. larger, with more premium products to increase the spending per visitor. She also wished that in the near future, she would be approved with the policy of building a small airport, serving tourism and national security, avoiding obstacles caused by weather and climate change. “Past generations of leaders have created a foundation for fundamental change in Co To island district. We want to continue to grow, making Co To become an indispensable destination for tourists ”, Mr. Son said.

Tri Ton district rural area and Chau Lang Commune People’s Committee. The model is designed according to the standards of rooftop solar power installed on construction works, tree-growing houses and instructions of EVN (Vietnam Electricity) with a capacity of 45Kwp, installed on an area of ​​400m2. of Mr. Chau Hon’s family. The model is completed and the grid is connected in December 2020. To ensure the efficiency of the plants underneath, the solar panels are designed with the right spacing, to ensure the growth of the plant variety. This is considered the first model with tripartite cooperation (people, businesses and non-profit organizations). The benefit sharing mechanism is discussed, agreed and harmonized among the participants. Agricultural production and sub-system farming activities are calculated and tested as soon as the system is completed with a number of short-term crops to assess growth and economic efficiency of the system. paradigm. The solar model associates agricultural production with double efficiency According to GreenID, the profit from the model will be divided among the parties according to the proportion of capital contribution invested. The disbursement period for Climate Sense is in the first 10 years because Climate Sense capital is meant to support initial investment. After 10 years, the whole system will be handed over to GreenID and households for management and use. After 20 years, GreenID will hand over to households full ownership. This model is expected to bring many multilateral financial benefits to the participants and facilitate as well as a typical model to call for more investors to expand. Farmers are excited Since commissioning in early 2021, the power generation portion is monitored remotely on the phone application. As recorded, the sunniest day, the model produces about 246Kwh of electricity and the lowest is 43Kwh on the day. On average, the system produces 103 kWh of electricity per day (as of April 7, 2021). Every month, electricity will record the indexes and payout on the amount of electricity sold to the investor’s account. From January to March 2021, the project has sold more than 4,471 kWh of electricity, equivalent to over VND 22 million. In this joint venture model, all participants benefit from the project. All profits earned from the sale of electricity to EVN will be distributed to the parties to the investment according to the profit sharing structure agreed upon by the parties in the joint venture cooperation contract. Joining the model, Mr. Chau Hon’s family and the project planted some new crops to test new crops for research. From January to April 2021, the research team collaborated with the project team and farmers to experiment with water spinach and cucumber to calculate the suitability of plants under solar panels and compare them with planting. outside. In fact, plants in the shade under solar panels grow well because they retain moisture, avoid direct sunlight due to extremely sunny weather and improved farming techniques. “I planted cucumber from February to 2021, the plants grown in a greenhouse under the panels outperform the control field outside, the fruiting rate is quite stable. Currently, my family harvests more than 30kg of cucumber per day. The fruit has a nice design and is long, fresh and delicious, highly appreciated by customers ”- Mr. Chau Hon said excitedly. Deputy Director of Department of Agriculture and Rural Development Truong Kien Tho said that the combination of agricultural production and solar power is a new model, showing initial efficiency. “When looking at the pictures of the panels covering the agricultural land, many people think it is impossible to cultivate. However, when choosing suitable crops, productivity and quality are higher. In the same arid land, farmers can keep an income from farming while also earning a monthly electricity bill. This is a model that can help many farmers to escape poverty sustainably and get better-off ”- Mr. Tho assessed. The model of installing solar cells combining agricultural production below helps generate additional revenue from selling solar power, making the most of arable land to increase income, and reduce conflicts in use. use of land resources. Some crops benefit from increased coverage, resulting in higher yields and better product quality

Minh Hoa Electricity Worker constructs and renovates the medium voltage grid. Mr. Nguyen Hoang, Minh Hoa Electricity Director, said that in 2020, Minh Hoa Electricity is one of the units in charge of the construction of many works under the major repair and construction investment source of Quang Binh Power Company. including the work of overhaul of the Minh Hoa medium voltage electrical network in 2020, the work to improve the reliability of electricity supply in Quang Binh province by 2020; works to reduce power loss of medium voltage electrical network in Quang Binh province by 2020.

Therefore, Minh Hoa Electricity determined that the concentration of management, operation, investment in construction and repair of the power system must be implemented according to a long-term and regular plan to increase supply reliability and quality. Electrical Power. “The goal of Minh Hoa Electricity is to strive to achieve an annual average commercial electricity growth rate of over 10% by 2022; the rate used to transmit and distribute electricity reached the plan assigned by Quang Binh Power Company; Average electricity price is 1,895 VND / kWh; electricity bill collection coefficient> 100% … Therefore, each employee of the whole Electricity must have the highest solidarity, unanimity, striving to comprehensively complete political tasks and economic and technical targets. art, steadfastly accompany the constant growth of heroic Minh Hoa homeland in the process of industrialization and modernization ”-ong Nguyen Hoang shared more.

Inauguration of a model combining agricultural production and solar power. The model will be deployed from May 2020, completed and connected to the grid in December 2020, exploiting electricity from the beginning of 2021. Solar power system with a capacity of 45kwp, installed on an area of ​​400m2, Below is a plant membrane house. Photovoltaic panels are designed with suitable spacing, ensuring the growth of plants. On average, the system produces 103kwh of electricity per day. From January to March 2021, the project has sold more than 4,471kwh of electricity, equivalent to more than VND 22 million. Underneath the panel system, farmers experimentally planted cucumbers. Cucumbers grown in the model had a higher fruiting rate than the outside control field. The fruits were long, beautiful, and the average fruit was harvested more than 30kg per day. Mr. Truong Kien Tho, Deputy Director of the Department of Agriculture and Rural Development of An Giang province, said that this is the first model of combining agriculture – solar power with a tripartite cooperation between people, businesses and teams. non-profit organizations are conducted in An Giang. The model helps farmers have dual income sources, increases production efficiency in a sustainable direction. The positive test results have proved the suitability and feasibility for replication. Farmers grow cucumbers in a net house, with solar panels above. Delegates visit the model.

Ms. Tran Vu Diem Hang, Green Development Innovation Center, said that the rooftop solar power system is a solar power system with photovoltaic panels installed on the roof of a building, with capacity? exceeding 1 MW, directly or indirectly connected to the electricity grid with a voltage of 35 kV or less of the buyer. Every region in our country has potential for solar power. For example, in Hanoi, the radiation intensity and total radiation are not small, the installation of grid-connected solar power brings high efficiency. The Northwest region also has solar energy potential … So, no matter where you live, people can install rooftop solar PV. For households, rooftop solar power saves electricity costs, reduces the pressure of paying high-tier electricity bills for households using a lot of electricity; increase household income because it is possible to sell excess electricity after it is used to EVN; help protect the roof to cool the roof, especially in the summer … A rooftop solar PV system consists of photovoltaic panels, power converters (inverters) and wires as well as a lightning protection system. Currently, the cost of installing a rooftop solar power system is not too expensive: the current investment price of 01 kWp ranges from 13-18 million VND depending on the size and origin of the equipment. However, in order to install solar power on the roof, people must pay attention to a number of points. First, the area must be large enough for installation. Accordingly, the roof area must be at least 6 – 7 m2 / kWp and 3 kWp should have a roof area of ​​21 square meters. You also need to make sure the roof is sturdy enough to place the mechanical system, the battery plate on top. In addition, the installation space must be ensured that there is no shade obscured by trees or other construction works. In particular, you must test the construction unit’s capabilities. Currently, each unit has its own capabilities, experience and standards leading to very different quality and price. Therefore, people should choose units with good capacity and years of experience.

However, electric cars are not perfect and they come with their own pollution problems. Typically, their batteries contain ingredients such as lithium, which require a considerable amount of energy to source and extract.

However, making batteries is only part of the life cycle of electric vehicles. A 2014 study published in the Proceedings of the National Academy of Sciences looked at the entire emissions life cycle of an electric vehicle, from mining the metals needed for batteries to producing the electricity needed. to power them, then compare this to the average emissions of a gasoline car. The team found that when electric cars are charged with coal-fired electricity, they actually do more harm to the environment than conventional gasoline cars.

Buying an electric car is much more affordable than a gas or diesel from an environmental perspective. Illustration

But that is not a problem because today, in most countries around the world, the national grid is “clean” enough for electric cars to beat competitors running on gasoline.

There are very few countries in the world where the grid is entirely or mostly coal. China is one of them. In 2019, an estimated 58% of the country’s electricity supply comes from coal. China’s grid is improving, however, with more investments in renewables – for example, it has twice the capacity of wind power as the US and builds more solar panels than any other country. Every year, according to Nature.

Mr. Gordon Bauer, an electric vehicle researcher at the International Council for Clean Transport in San Francisco, USA, said the current improved grid model, with more renewable energy and less fossil fuels. , is a global model and helps improve the environmental quality of electric vehicles. “As the grid becomes” greener “, the use of electric vehicles will be more perfect,” he said.

In a study published this month in the journal Environmental Science and Technology, Colin Sheppard, a researcher in energy and transport systems engineering at Lawrence Berkeley National Laboratory in California, Work with Gordon Bauer to model a hypothetical future scenario where all cars are powered by electricity. “We want to understand the impact of energy, infrastructure and emissions if all passenger vehicles are electrified,” Sheppard told Live Science.

For example, Mr. Sheppard calculated that if all private vehicles in the United States were powered by electricity, the annual reduction in greenhouse gas emissions in the country would be 46% (0.5 gigatons of CO2) compared to cars. run on conventional gas.

This reduction could be further increased if the vehicles were subjected to so-called “controlled charging”, a technique also known as “smart charging”, in which the vehicles are recharged into Timing is selected to minimize the financial cost of electricity generation. (For example, charging at night is generally less expensive than during the day; this strategy also favors plants that produce more energy efficiently to generate cheaper electricity.) If all privately owned electric cars were charged in the same way, emissions savings could be increased by up to 49% annually.

In addition, electric vehicles are said to also emit CO2, but not during use, but when generating electricity – this is why many people believe that this car is not completely pure. Even the president of Toyota once harshly said that electric cars are being overblown.

In fact, electrochemical vehicles including Hybrid (HEV), Plug-in Hybrid (PHEV) still emit CO2 even when used (because there is still an internal combustion engine) and possibly when generating electricity, depending on how it is generated. electricity. While pure electric vehicles can only generate CO2 in the production process, not when used.

Depending on the source of electricity generation is hydroelectricity, wind power or thermal power, nuclear power … that the amount of CO2 generation will be different. If hydroelectricity, CO2 level is almost zero, while thermal power is too much CO2.

Research by Bloomberg NEF in Thailand shows that electric cars generate 60% of the CO2 equivalent of a gasoline equivalent vehicle. This source of CO2 comes entirely from production, because Thailand generates electricity mainly from natural gas. While internal combustion engine vehicles produce CO2 in an 80/20 ratio between use and production.

For example, if a gasoline car generates 100 g CO2 / km 80 g from use and 20 g from gas production. While a corresponding electric car model only generates 60 g of CO2 from use. As such, electric cars are still significantly cleaner than gasoline cars.

For countries with clean electricity generation sources such as Norway, up to 95% of electrical energy comes from hydroelectricity, CO2 emissions are even lower. The future of electric vehicles is becoming clearer as more automakers are involved in the production and research of electric vehicles. Users often do not care too much about CO2 emissions in production, but realize that when used, it will help where cars circulate with less pollution.

Ultimately, the conclusion is that buying an electric car is much more affordable than a gas or diesel car from an environmental perspective.
