Revenue & offtake the regime the project was built under
Offtake regime: ROC 2.5 ROCs/MWh (demonstrator) - rate unverified, flagged
RegimeROC 2.5 ROCs/MWh (demonstrator) - rate unverified, flagged
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.
