Recently, the State Grid Corporation of China issued a notice on Actively Striving for the Pilot Project of Distributed Photovoltaic Development on the Roof of the Entire County (City, District), and organized various units to actively carry out the pilot application work to fully develop the distributed photovoltaic market. As the state grid company with the most grid-connected photovoltaic projects, according to the data published by the State Grid Co., Ltd. Service New Energy Development Report (2021), in terms of wind power and photovoltaic installed capacity, in 2020, the State Grid business area will increase The grid-connected installed capacity of wind power and solar power was 100 million kilowatts, the utilization rate of new energy increased to 97.1%, and 587.2 billion kilowatt-hours were consumed throughout the year. As of the end of 2020, the installed capacity of new energy is 450 million kilowatts (230 million kilowatts of wind power and 220 million kilowatts of solar power).

In 2020, the newly installed capacity of solar power generation in the operation area of the State Grid will be 39.41 million kilowatts, 1.6 times that of 2019. As of the end of 2020, the installed capacity of solar power generation was approximately 220 million kilowatts, accounting for 85% of the country's total and 12.7% of the total installed capacity of power generation in the State Grid operating areas, an increase of 9.6 percentage points from 2015. During the "13th Five-Year Plan" period, the cumulative installed capacity of solar power generation was 180 million kilowatts, five times that of the "Twelfth Five-Year Plan".

In the document issued this time, State Grid clearly requires that in order to implement the requirements of the National Energy Administration and fully develop the distributed photovoltaic market, the State Grid Marketing Department has decided to organize various units to actively carry out the pilot application work. At the same time, all provincial companies should pay close attention to connecting with the provincial Energy Bureau (Development and Reform Commission) and other competent departments; all provincial companies should cooperate in the inspection of roof resources, focusing on party and government agencies, schools, hospitals, village committees, industrial and commercial plants, etc.; all provincial companies should contact the government Put forward supporting policies suitable for the development of rooftop photovoltaic resources in various regions, and strive to increase the level of project income; State Grid Comprehensive Energy Service Group, NARI Group, and State Grid Energy Institute should combine recent research on photovoltaic resources and photovoltaic project development solutions. Achievements, cooperate with various provincial companies to do a good job of resource investigation; State Grid Comprehensive Energy Service Group must implement follow-up project investment funds in advance according to the results of resource investigation.

Prior to this, the National Energy Administration issued the "Notice on Reporting the Pilot Program for the Start of the Distributed Photovoltaic on the Roof of the Whole County (City, District)." The "Notice" pointed out that the pilot counties (cities, districts) applying for the project must have abundant roof resources and good absorbing capacity, and that the proportion of photovoltaic installations in the total roof area of party and government agencies should not be less than 50%, schools, hospitals, etc No less than 40%, no less than 30% of industrial and commercial distribution area, no less than 20% of the roof of rural residents.

Up to now, 16 provinces and cities including Jiangsu Province, Shanghai, Liaoning Province, Henan Province Development and Reform Commission have successively issued the "Notice on Reporting the Pilot Program for Promoting (City, District) Roof Distributed Photovoltaic Development of the Whole County" and other 16 provinces and cities forwarding notices, requiring correct County advances. In addition, the State Power Investment Corporation also issued a document requesting to declare and seize rooftop resources. Editor/Xing Wentao、Design/Zhangtao
