China Launches Gigantic Offshore Solar Plant While America Falls Further Behind

A behemoth of steel and silicon now floats off China’s eastern coast. The world’s largest open-sea offshore solar installation just powered up in Shandong Province, and it’s a monster: 1 gigawatt capacity. That’s 1,000 megawatts. America isn’t even in the game.

Located 8 kilometers offshore from Kenli District, this massive project spans 1,223 hectares of shallow coastal waters. Guohua Investment, a subsidiary of China Energy Investment Corporation, dropped a cool 8.1 billion yuan (about $1.2 billion) to make this happen. Meanwhile, U.S. offshore solar remains basically nonexistent. Funny how that works.

The infrastructure is mind-boggling. Try 2,934 enormous steel platforms, each one bigger than five basketball courts. Each platform sits on steel piles driven deep into the seabed, designed to withstand everything from powerful gales to seasonal sea ice. Not exactly a weekend DIY project.

The scale defies imagination—thousands of massive platforms anchored to the seabed, laughing at typhoons while America watches from shore.

They’ve installed over 2.3 million n-type bifacial solar modules, each cranking out 710 watts. The panels sit at a precise 15-degree angle, capturing both direct sunlight and the bonus rays reflected off the water. Efficiency boost? 5-15% over land-based systems. Not too shabby.

This isn’t just about bragging rights. The facility generates 1.78 billion kilowatt-hours annually, covering about 60% of Kenli District’s electricity needs. That’s enough juice for 2.67 million urban residents. No coal required—the project saves 500,000 tonnes of the black stuff every year and avoids 1.34 million tons of CO₂. The innovative system also includes a 100 MW/200 MWh storage component to ensure grid stability during cloudy days.

The smart part? They’re using the space below for aquaculture. Solar panels up top, farming below. Double-dipping at its finest. The installation is supported by exactly 11,736 steel piles that were engineered to use 10 percent less steel than conventional designs. This project exemplifies why China will account for 56% of global renewable capacity expansion through 2028.

China reached full-capacity grid connection in December 2025. It’s their first gigawatt-scale fixed-pile offshore PV project. First in the nation, first in the world. America? Still talking about it. Still planning. Still falling behind.
