China National Nuclear Power starts work on nation’s largest offshore solar farm
- The 2GW pilot project is coming up on mud flats near its nuclear power station in Tianwan, in eastern Jiangsu province
- The 9.88 billion yuan (US$1.4 billion) project will include a 0.4GW energy-storage facility and cover an area larger than Hong Kong’s Tseung Kwan O district

State-backed China National Nuclear Power (CNNP) has kicked off construction of the nation’s largest offshore solar farm, as part of efforts to boost low-carbon energy supply and decarbonise the economy.
“Upon completion, it will cross couple with the nuclear power station, forming a 10GW large-scale clean-energy production base,” the utility said in a filing to the Shanghai exchange on Monday, adding the solar farm will generate 2.23 billion kilowatt-hours of power during its 25-year lifespan.
The solar farm will include a 0.4GW energy-storage facility. Together, the project will cost 9.88 billion yuan (US$1.4 billion). Its solar panels will cover 18.8 square kilometres, slightly larger than Hong Kong’s Tseung Kwan O district.
CNNP, a unit of state-owned China National Nuclear Corporation, one of the nation’s largest nuclear power plant developers and operators, has a 90 per cent stake in the project.
CNNP operates 25 nuclear power generating units with a total generating capacity of 23.8GW as of last year. Another 15 units totalling 17.6GW are under construction.
