Revenue & offtake the regime the project was built under
Offtake regime on record
RegimeThe farm company's own accounts (FY2021, FY2024) state that it has sold its power by direct marketing under the EEG since July 2019, with Vattenfall Energy Trading as direct marketer. At financial close (August 2017) Northland put the EEG support at approximately EUR 184/MWh for 8 years and EUR 149/MWh for the remainder of an approximately 13-year period, after which the farm sells into the wholesale market; the accounts state no rate.
Instrumentmarket premium
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.
