Recently, China's first million-kilowatt offshore photovoltaic project—the HG14 Offshore Photovoltaic Project of Guohua Energy Investment in Dongying, Shandong—achieved full-capacity grid connection. This marks the largest open-sea offshore photovoltaic project in China at present. The annual power generation is projected to reach 1.78 billion kilowatt-hours, capable of meeting 60% of the total electricity demand in Kenli District, Dongying City, where the project is located.

The project is situated in the eastern waters of Dongying City and is constructed in four phases, with a total installed capacity of 1,000 megawatts. Moreover, the project pioneers the use of large-scale offshore steel truss platform fixed pile foundation construction technology globally, building 2,934 photovoltaic platforms. Each platform measures 60 meters in length and 35 meters in width, equivalent to the size of five standard basketball courts.

It is understood that the project is expected to save 503,800 tons of standard coal and reduce carbon dioxide emissions by 1,344,700 tons annually, providing robust support for advancing the local green and low-carbon transition.
