Portland General Electric (PGE) has finalised agreements for more than 1,000MW of new renewable energy and battery energy storage system (BESS) projects in the US state of Oregon.
These projects were procured through PGE’s 2023 all-source request for proposals (RFP), power purchase agreement (PPA) procurements, and the 2025 RFP. The utility said it represents the largest renewables acquisition in its history.

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.
