China's Seas Power Up: Offshore Wind & Solar Surge

Coastal provinces in China are maximizing limited marine space through innovative renewable energy projects. In Fujian province, solar farms are now situated on abandoned tidal flats, with steel pillars supporting panels above the water, allowing aquaculture activities to continue below. This approach is exemplified by a 180,000-kilowatt solar farm in Dongshan county, China's first offshore solar project in a high-wind-speed zone.

Nationally, China has approved over 200 offshore wind projects, achieving a cumulative grid-connected capacity exceeding 47 million kW, positioning it as the global leader for five consecutive years. Fujian's strong winds and long coastlines provide ideal conditions for both offshore wind and solar power generation, which are complementary, ensuring a more stable energy output.

China's offshore wind industry has seen rapid advancements, with domestic production of key components achieving 100 percent. Turbine sizes have dramatically increased, with the world's largest 26-megawatt offshore wind turbine rolling off the production line in 2024. The nation's 15th Five-Year Plan (2026-2030) sets an ambitious target of 100 million kW of offshore wind capacity by 2030, signaling a strong commitment to clean energy and economic growth.

Developing offshore wind along China's eastern seaboard offers logistical advantages, including shorter transmission distances to consumption centers and reduced infrastructure costs compared to western power transmission. The industry is also pushing further offshore, with site-selection standards evolving to deeper waters and greater distances from shore. China is exploring new frontiers, including undersea data centers powered by offshore wind.
