The largest offshore wind power farm in Zhejiang was put into use in Zhoushan on May 16, local media reported.

Daishan No 4, along with the upcoming Shengsi No 5 and No 6 offshore wind power farms, consists of the largest offshore wind power farms in the province.

These wind power farms are operated by China General Nuclear Power Corp (CGN), the largest nuclear power constructor worldwide.

Daishan No 4 includes 54 wind turbine generators, with a total installed capacity of 234 megawatts.

The wind power farm can generate 618 million kilowatt-hours (KWH) per year, saving 170,000 metric tons of coal and reducing emissions of noxious gases by 470,000 tons.

All the electricity generated by Daishan No 4 is expected to be supplied to the Zhejiang Zhoushan Green Petrochemical Base on Daishan Island.

Zhoushan is abundant in wind power resource. As of the end of 2020, Zhoushan had housed five centralized wind power stations, with a total installed capacity of 654,000 kilowatts, accounting for 30 percent of the total wind power generated in Zhejiang.

In 2020, Zhoushan generated 345 million KWH via wind power stations, saving 120,000 tons in coal and reducing the emission of carbon dioxide by 300,000 tons.

In addition, the offshore wind power farm can generate 20 to 40 percent more electricity than onshore one per year.
