The Oregon Public Utility Commission (OPUC) supervises these processes with the intended goal of all bids being assessed in a fair, impartial, and transparent manner.

Following the completion of contract negotiations, PGE and third-party developers will initiate construction planning for new renewables and BESS projects totalling 1015MW, with 42% utility-owned and 58% under PPAs. These resources are projected to start serving customers in 2027 and 2028.
