China’s Offshore Solar Giant Is Real, and It’s Doing the Most
Click to watch: China’s HG14 offshore solar project turns the sea into a power grid, with fish farming reportedly sharing the space below.
Dear Cherubs, China has done what it so often does with infrastructure: taken a perfectly sensible idea and scaled it up until it looks like a dare. Off Dongying, in Shandong province, CHN Energy says it has brought online a 1-gigawatt open-sea offshore solar project built with 2,934 PV platforms, more than 2.3 million modules, and 11,736 steel piles hammered into the seabed. In other words, it is solar power, but with a shipping-industry gym membership.
A SEA OF PANELS
This is not your garden-variety floating array. CHN Energy describes the project as a fixed-pile offshore PV system, designed to sit about 8 kilometers from shore and handle waves, tides, strong winds, and seasonal sea ice without immediately filing for retirement. pv magazine reported that the panels are mounted on 60-by-35-meter steel platforms, tilted at 15 degrees, and connected through a 66-kilovolt subsea cable system with onshore transmission infrastructure. So yes, the engineering is serious. The drama is mostly in the size.
WHY IT MATTERS
The developer says the plant should generate about 1.78 billion kilowatt-hours of electricity a year, enough to meet the needs of roughly 2.67 million urban residents, while avoiding around 1.34 million tons of carbon dioxide and saving more than 500,000 tons of standard coal. Those are company estimates, so treat them as reported projections rather than holy scripture, but the basic point is hard to miss: this is a very large clean-power machine with a very large ambition. CHN Energy also says the site uses a “PV-above, farming-below” model, mixing power generation with aquaculture. Multi-use land? More like multi-use sea.
The timing is not random either. Reuters reported that China connected the world’s largest solar farm in Xinjiang in 2024, and The Guardian reported in June 2025 that China added 198 gigawatts of solar and 46 gigawatts of wind in just the first five months of the year, with installed solar capacity passing 1,000 gigawatts. So this offshore project is not a quirky one-off; it is part of a national habit of building renewable energy at a scale that makes other countries look like they are still printing brochures.
The hot take is simple: the future of solar may not always be rooftops and deserts. Sometimes it looks like a steel fortress at sea, built to wrestle weather, salinity, and gravity into submission.
