Deploy in advance in multiple locations, tap into potential, and schedule reasonably - ensuring electricity supply during peak and summer seasons
2023-07-03
As the overall economic situation improves and summer temperatures rise, the demand for electricity further increases. Relevant departments and power enterprises in various regions deploy power supply guarantee work, do a good job in supply and demand forecasting, cross provincial power support, unit maintenance, and other work to ensure that electricity demand is guaranteed. Recently, Megaproject have been put into operation at an accelerated pace. We have strengthened energy planning in many places, accelerated the construction of power generation projects, and fully guaranteed the demand for electricity for production and living in the summer. As a major electricity consuming province, Guangdong's electricity load is greatly affected by temperature. To avoid power shortages in the summer, multiple power construction projects invested in earlier stages in Guangdong have been put into use before peak electricity usage. On May 31st, the transmission project of the 500 kV Guohua Qingyuan Power Plant was fully completed, which is a key annual backbone power supply construction project in Guangdong Province. At the same time, five key projects, including the 500 kV Chenghai Transmission and Transformation Project and the 500 kV Shanwei Switching Station, were successfully put into operation in May to meet peak and summer demand. Guizhou requires all regions to scientifically carry out water conservation, drought resistance, and energy storage and power generation work while ensuring flood control safety. In early May, the Energy Bureau of Guizhou Province proposed requirements for energy enterprises in their jurisdiction to welcome peak summer weather. On the one hand, they should focus on the normal production and construction of coal mines and fully release coal production capacity; On the other hand, we should ensure the performance of medium and long-term contracts for electric coal, fully guarantee the supply of electric coal, complete the tasks of medium and long-term contracts with high quality and quantity, improve the calorific value of long-term cooperative electric coal, and strictly supervise the performance of electric coal. To ensure stable power supply during the peak summer season, the Hubei Provincial Power Department has deployed 28 key projects in advance, with 431.72 kilometers of new transmission lines and a new substation capacity of 3.16 million kilovolt amperes. At present, 11 projects including the 500 kV transmission line project of Suizhou Power Plant have been successfully put into operation; The first unit of the largest water conservancy and hydropower hub project under construction in Hubei, Nianpanshan Water Conservancy and Hydropower Hub Project, was put into operation for power generation. The person in charge of State Grid Hubei Electric Power stated that after all key projects are put into operation, the structure of the Hubei power grid will be strengthened. On June 30th, the world's highest voltage level and largest transmission capacity flexible low-frequency transmission project was put into operation in Hangzhou. The rated transmission capacity of the project is 300000 kilowatts, achieving the first engineering application of 220 kV low-frequency equipment. Xu Ting, from the Operation and Inspection Department of State Grid Hangzhou Power Supply Company, told reporters that during the Hangzhou Asian Games, this project can effectively alleviate the peak electricity consumption pressure on the power grid, enhance the flexibility and mutual assistance ability of electricity, and enhance the guarantee of electricity supply in the core areas of the Hangzhou Asian Games and the peak summer season. Strengthen the management of energy utilization scheduling, focus on tapping potential, establish specialized teams for power supply guarantee work in multiple places, comprehensively strengthen the command, scheduling, and coordination of power supply guarantee, and tighten and compact responsibilities. In order to ensure the peak summer electricity demand in Guangdong, Southern Power Grid has increased its efforts in cross provincial assistance, organizing western provinces to support the eastern power supply through direct increase in electricity transmission and other means, ensuring the safe and reliable supply of electricity in Guangdong. Currently, the Fujian Guangdong interconnection project is transmitting electricity from Fujian to Guangdong according to the maximum capacity of the current channel. As of June 27th, the Fujian Guangdong Interconnection Project has delivered over 2 billion kilowatt hours of electricity to Guangdong, providing strong support for the stable recovery of Guangdong's economy. According to calculations, during the 14th Five Year Plan period, through the connection between Fujian and Guangdong, the seasonal power transmission between the two regions could reach 500000 to 1.6 million kilowatts.
