China has commissioned the world's largest open-sea solar project, the 1 GW HG14 offshore PV project off the coast of Dongying, Shandong province. The project combines PV with energy storage and aquaculture, occupying 1,223 hectares of shallow coastal waters. The installation is China's first gigawatt-scale fixed-pile offshore PV project, approved under a national sea-use rights framework. The project is expected to generate 1.78 TWh annually, meeting 60% of electricity demand in the area, while also reducing CO2 emissions and integrating aquaculture for additional revenue streams.
