With always having load forecast, with short and long-term solutions to respond; investing in many new substations as well as increasing the capacity of substations, this year’s hot season electricity in the city as well as localities in Nghe An will be guaranteed, and remote areas will also be provided with electricity. safe electricity.
Build multiple response scenarios
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.
