Lanzhou, November 11 (Gao Zhan) "This winter's extremely cold weather is very likely, with the peak of winter approaching, the peak period of electricity consumption, winter heating period, hydropower dry period three superimposed, Gansu Province electricity load is expected to reach the maximum of 18.5 million kilowatts, an increase of 6.87% year-on-year." Xingzhou, deputy general manager of the State Grid Gansu Provincial Electric Power Company, said on the 11th.
On the same day, the State Grid Gansu Electric Power fully guaranteed the power supply press conference this winter and next spring was held in Lanzhou. Xingzhou said that considering the impact of factors such as medium- and long-term delivery contracts and fluctuations in new energy output, the Gansu power grid this winter and next spring presents a situation of "overall tight balance and tight power supply in local time".
This year, the load growth in Gansu Province exceeded expectations, as of the end of October, the growth rate was as high as 10%, and multiple factors such as winter irrigation and heating load in November and December were superimposed, and the Gansu power grid will usher in the period of the largest annual electricity load.
In order to prepare for the peak winter, Gansu Electric Power has taken many measures to eliminate hidden dangers. The picture shows the UHV power grid that crisscrosses the skyline of the Hexi Corridor. (Data map) Courtesy of Gansu Provincial Electric Power Company
In view of the current supply situation and the continuous occurrence of extremely cold weather, the State Grid Gansu Electric Power Science arranges the operation mode of the power grid, strictly implements the power grid operation procedures, pragmatically implements the "foundation" of power grid security, and keeps the bottom line of safe and stable operation of the system.
Xingzhou said that in order to ensure the safe and stable operation of the power grid and maintain the stability of the social electricity order, the State Grid Gansu Electric Power reasonably arranges the operation mode of the power grid, rolls out the forecast of electricity load and new energy power generation, reasonably arranges the start-up mode of thermal power according to the thermal coal inventory, refines the dispatch and operation of thermal power, and reduces the consumption of thermal coal. Urge thermal power to strengthen equipment operation and maintenance management, improve the peak capacity of units, effectively reduce unplanned downtime, restore temporary inspection units as soon as possible, and release power generation capacity。
At the same time, Gansu Electric Power strengthened inter-provincial mutual assistance, expanded the scale of power purchases, and purchased a total of 6.388 billion kWh of electricity from Xinjiang, Sichuan and other provinces by the end of October, which is equivalent to the electricity sold in Jiayuguan City, Gansu Province in 2020. Coordinate the arrangement of equipment maintenance, eliminate equipment defects in time, and during the winter period, do not arrange maintenance that affects the ability to keep warm and supply, and maintain the integrity of the power grid structure to the greatest extent.
Before the end of December, Gansu Electric Power strives to complete the 6 million kilowatts of new energy installed capacity in advance of the grid. The picture shows the photovoltaic power plant in Longnan Mountain. (Data map) Courtesy of Gansu Provincial Electric Power Company
Cheng Ming, secretary of the party committee and deputy general manager of the marketing division of the State Grid Gansu Electric Power Company, said that during this period, Gansu Electric Power will also formulate a plan for ensuring the people's livelihood electricity, implement a 24-hour emergency duty system, ensure the people's production and living needs and the stable operation of the economy and society, and resolutely adhere to the bottom line of people's livelihood electricity.
Xingzhou called for the hope that all industrial enterprises would optimize and adjust their production plans, optimize and adjust the timing and length of electricity consumption of lighting, air conditioning and other equipment through staggered peak production, shift operation, rotation and suspension of production, reduce non-production and non-essential electricity consumption, try their best to use electricity for production links, and improve the efficiency of power resource utilization. Shopping malls, hotels, office buildings and other places reduce the use or stop using high-powered power equipment during peak hours to support the easing of power supply pressure. The whole society acts together to become an advocate, communicator and practitioner of saving electricity. (End)
