Revenue & offtake the regime the project was built under
Offtake regime on record
RegimeThe farm company's accounts state that it sells its power by direct marketing under the EEG through a direct marketer (contract concluded in 2015; a new contract with Danske Commodities from 1 Jan 2022), under the compressed tariff model (Stauchungsmodell) with a reference value of 19.4 ct/kWh. In 2022 market values in some months were above 19.4 ct/kWh and raised the farm's revenue. The accounts held (FY2019, FY2021, FY2022) do not say how long the 19.4 ct/kWh rate runs or what rate follows.
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.
