The full-capacity grid-connected power generation of the 300MW photovoltaic "new energy + energy storage" project jointly constructed by our company and a cooperative company. It is reported that the project introduces energy storage technology while photovoltaic power generation, which effectively solves the problem of supply and demand distribution of solar power generation. After being connected to the grid, it is estimated that the average annual power generation will be about 430 million kWh, saving about 125,000 tons of standard coal and reducing carbon dioxide emissions by about 342,000 tons per year.
