Revenue & offtake the regime the project was built under
Offtake regime of the vintage — not a recorded contract
Wind feed-in tariff for offshore projects (Decision 39/2018/QD-TTg)
Built under Viet Nam's 2018 wind tariff: offshore (including nearshore) wind projects in commercial operation before 1 November 2021 sell to EVN at VND 2,223/kWh excluding VAT — 9.8 US cents/kWh at the 30 August 2018 rate, adjusted with the VND/USD rate — fixed for 20 years from the commercial operation date. Plants that missed the deadline fall under the transitional pricing that followed, recorded on the project where a source states it. · ◇
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.
