China’s Megaproject Promises to Revolutionize the Offshore Solar Energy Sector. The Offshore Solar Plant Will Be the Largest in the World, Generating Power for 2.6 Million People.
This week, CHN Energy, a state-owned energy company in China, connected the first batch of solar panels from the world’s largest offshore solar plant to the power grid. China’s solar energy megaproject is located 8 km off the coast of Dongying, in Shandong Province, covering 1,200 hectares. The largest offshore solar plant has nearly 3,000 photovoltaic panels, each measuring 60×35 meters.
China’s Megaproject Will Supply Power to 2.6 Million People Annually
The total capacity of the largest offshore solar plant is 1 Gigawatt, enough to supply 2.6 million people annually. The country, the world’s largest energy consumer, is accelerating its transition to renewable sources with this Chinese megaproject. In addition to generating energy, the largest offshore solar plant includes fish farming, maximizing the use of marine space. This milestone symbolizes China’s energy transition in recent decades.
It is worth mentioning that JinkoSolar provided its Tiger Neo bifacial modules with tunnel oxide passivated contact n-Type (TOPCon) for the project. The company claims it has adapted its modules for harsh maritime conditions, using dual glass, semi-tempered glass, and POE encapsulation to withstand humidity, corrosion from salt mist, exposure to seawater, strong winds, and extreme temperatures.

Petrobras reaffirms its commitment to the market and ensures that it will carry out the energy transition safely to maintain national sovereignty.

Researchers discover a possible hydrogen deposit of up to 46 million tons beneath an ancient coal basin, and the volume could exceed half of the entire global production.

China bets on the Fishery-PV model and transforms fish farms into giant solar plants, covering ponds with panels that generate energy while utilizing the same space for large-scale aquaculture production.

Green hydrogen at home: Belgium launches new technology that makes solar panels produce fuel from the moisture in the air, which could boost the energy transition.
CNH Energy states that it is using an integrated model for the development of fishery and photovoltaic energy, as it is the second-largest offshore solar plant. The largest completed floating offshore solar array in the world is currently a 440 MW project in Taiwan, which was commissioned earlier this month.
Understanding China’s Megaproject Plans with the Implementation of the Largest Offshore Solar Plant
China is advancing plans to harness more of its vast solar resources as it moves towards full market liberalization by the end of the decade. Zhejiang Province, one of the growth engines of the economy on China’s east coast, has drafted a proposal to encourage commercial users to utilize less regulated energy.
While fixed contracts, with prices set by the government, will continue to dictate 90% of the market, the other 10% will be opened for spot trading, according to a consultation document from the Zhejiang Power Trade Center published by the news channel BJX.com.
Other Chinese provinces are working on their energy trading plans for 2025. Countries like the United Kingdom use similar programs to ensure the availability and profitability of clean energy. In 2023, China reached the milestone of 1.2 TW of installed capacity in solar and wind energy, achieving its goals set for 2030 six years ahead of schedule.
Renewable energies in China are becoming increasingly cheaper than alternatives after a significant increase in capacity, but they are not always fully utilized because they cannot be relied upon when there is no wind or sun, particularly in a fragmented market.
Another Megaproject in the Photovoltaic Sector Gains Attention
In addition to CHN Energy’s largest offshore solar plant, China announced last year the installation of the Fuyang megaproject. The offshore solar plant has over 1 million photovoltaic panels, equivalent to 1,300 football fields. The location where the floating plant is installed is also the largest well-utilized idle area in a coal mining area.
The largest offshore solar plant was built in a water area formed by approximately 13,000 acres of coal mining subsidence. Its total installed capacity is 650,000 kilowatts, with 122 massive photovoltaic arrays, capable of providing an average annual energy generation of around 700 million kilowatt-hours.
