Revenue & offtake the regime the project was built under
Offtake regime of the vintage — not a recorded contract
Post-subsidy era — provincial pricing (NDRC notice 2021)
Built after the national subsidy ended. From 2021, newly approved offshore wind projects are priced by the provincial price authority — through competitive allocation where conditions allow — with no central subsidy; the grid company settles the part within the local coal benchmark price. A project approved before 2021 that connected after the 2021 deadline takes the guide price of its connection year. Provincial top-ups (Guangdong, Shandong, Zhejiang and others) exist and are recorded on projects only where a source states them. · ◇
A built project sells its power under the contract or support regime it was financed with; it is not expected to bid into new government offtake rounds. Where the record does not yet name that regime, the row says so rather than guessing.
