On May 13th, amidst the green fields of Yangdian Township in Feidong County, Hefei City, scattered small and medium-sized photovoltaic power stations harness the sun's energy, continuously generating stable green electricity. This is the recently grid-connected 220 kV Jinko Guanwan Photovoltaic Power Station.
Feidong County is rich in pond resources, though they are widely dispersed. Leveraging this local characteristic, the project selected over 400 idle ponds across Yangdian Township, Badou Town, and Yuantuan Town, aggregating these distributed resources to build floating solar power stations. The first and second phases of the project were officially connected to the grid at the end of April this year, with a total capacity of 200 megawatts. The estimated annual power generation is approximately 250 million kilowatt-hours. Compared to a thermal power plant of the same scale, this project can save about 88,800 tons of standard coal and reduce carbon dioxide emissions by approximately 233,400 tons annually.
Currently, construction is steadily progressing on the project's third phase, along with a supporting 100-megawatt wind farm and a 168 MW / 336 MWh new energy storage power station. Once the entire station is operational, the total installed capacity is expected to reach 560 megawatts, forming a more secure and efficient "source-grid-load-storage" system. During peak midday solar generation, the energy storage station can store and shift a portion of the electricity for use during the evening peak period after 7 PM, effectively promoting the integration of new energy and enhancing the regional grid's power supply and regulation capabilities.
In recent years, Hefei City has experienced rapid industrial development and an accelerating pace of green transformation. To balance power supply security with the green transition, Hefei Power Supply Company has focused on the core strategy of "aggregating sources, strengthening the grid, and integrating loads," accelerating the construction of a secure, reliable, clean, low-carbon, flexible, and efficient new urban power system.
In terms of green energy development, the installed capacity of new energy in the Hefei power grid has been continuously increasing, with new energy now becoming the primary power source in the city. As of now, the total installed capacity of new energy in the Hefei area is 7,848.8 megawatts, ranking first among all provincial capital cities in China and accounting for 57.8% of the city's total power generation capacity.
