Nationwide electricity generation Coal is overtaking wind power again

Status: 06/11/2021 1:53 p.m.

A spring without storms has led to a decline in wind energy. Coal grew to become the most important energy source in the country in the first quarter. At the same time, the demand for electricity is increasing, says Minister of Economic Affairs Altmaier. Electricity production using coal in Germany overtook wind power again in the first quarter of 2021. According to the Federal Statistical Office, a “windless spring” resulted in almost a third less electricity from wind power. According to the authorities, the gap has been filled by increasing electricity generation from coal and natural gas power plants. From January to March inclusive, a total of 138.2 billion kilowatt hours of electricity was generated and fed into the grid. According to preliminary results from the Federal Office, that was 2.6 percent less than in the first quarter of 2020.

Coal, gas and nuclear power dominate

While the electricity in the same period last year came mainly from renewable energy sources such as wind power, biogas and sun (51.4 percent), coal, gas and nuclear energy dominated at the beginning of this year (59.3 percent). With a share of 28.9 percent of the total amount of electricity fed into the grid, coal was the most important energy source for electricity generation in Germany in the first quarter of this year. The amount of electricity generated in coal-fired power plants increased by more than a quarter (26.8 percent) to almost 40 billion kilowatt hours compared to the same period in the previous year. The amount of electricity from natural gas increased by 24 percent to 22.5 billion kilowatt hours. In contrast, there was a strong minus of almost a third (32.4 percent) in wind power: The feed-in of 33.5 billion kilowatt hours was the lowest value for this energy source for a first quarter since 2018. In the two previous years, there was wind power significantly higher values ​​achieved due to strong spring storms.

Altmaier sees increased demand for electricity

Meanwhile, Federal Minister of Economics Peter Altmaier admitted that his department had so far underestimated how much the demand for electricity in Germany is likely to increase in the course of the energy transition. “Due to the more stringent climate targets in Germany and the EU, we have to assume a significantly higher electricity demand than was previously assumed,” said the CDU politician to Wirtschaftswoche. “My house will submit new calculations for this.” Altmaier said that more energy must be produced, “from all available renewable sources: wind power and photovoltaics”. Altmaier said that he would present specific proposals on how offshore wind power on the high seas and other renewable energies could be expanded more than previously planned. For “green hydrogen” for use in the steel industry or the expansion of electromobility, many experts believe that significantly more electricity will be required in the coming years, which should come from renewable energies.

SPD puts pressure on

The SPD criticized Altmaier: “For months now, the SPD and the entire German industry and energy sector have been calling on the Federal Minister of Economics in vain to anchor realistic electricity requirements and a correspondingly ambitious expansion of wind power and photovoltaics in the EEG,” said parliamentary group vice-president Matthias Miersch of the dpa news agency. If Altmaier now announces new proposals, which can only then be implemented by the next federal government, it is “poor” and unworthy of a federal minister of economics, according to Miersch. The SPD had already submitted proposals months ago which, based on realistic electricity consumption, determine the associated expansion paths for green electricity up to 2030 and contain funds for acquiring space and accelerating it. “We could implement this next week,” said the politician.

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/.

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.

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.

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.
