From Hafrok’s transactions record
Dashed tick marks today (9 Sep 2026). Ownership lives in the band below: one station per recorded deal, dated at its label, in deal order rather than to calendar scale. Secondary trades appear only at the interchanges; grey lines are parties whose entry or exit Hafrok’s record does not hold.
Revenue & offtake the regime the project was built under
Offtake regime: Japan FIT (20-year PPA with Tohoku Electric)
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.
