(Summary description)In order to avoid the good development of distributed photovoltaic power generation projects, the State Grid adopts the method of prior investment subsidies for photovoltaic power generation projects, which may indeed cause the problem of construction but not use. As far as State Grid Corporation of China is concerned, we encourage customers to generate more electricity by actively implementing the measures of surplus electricity grid connection and full purchase.

Two aspects are mainly considered when determining a photovoltaic power generation project with a total installed capacity of not more than 6 MW:
First, the opinion stipulates that a single grid connection point should not exceed 6 MW, rather than the entire project. This means that if an owner has a lot of roofs, the total photovoltaic power generation capacity is very large and will not be restricted. As for the single grid connection point, the upper limit of 6 MW is related to the capacity of the 10 kV line. The transmission capacity of a 10 kV line is 5 to 8 MW, and 6 MW is set to match the 10 kV line. Therefore, the first consideration is to match the single-point access capacity with the distribution network.
Secondly, this regulation is also related to relevant national requirements. According to the data statistics requirements of the National Bureau of Statistics, power supplies with a capacity of 6 MW and above are considered as large power sources and should be included in the national statistics. We have also done calculations. 1 MW of photovoltaic power generation capacity covers an area of ??4 acres; for 6 MW, it is 24 acres. There is no roof with such a large area. Therefore, the single-point access capacity of 6 MW can cover various distributed projects such as rooftop photovoltaic, photovoltaic construction integration, and rural courtyard photovoltaic projects.
