PORTLAND, Ore. — Portland General Electric has finalized agreements for more than 1,000 megawatts of new clean energy and battery storage, marking major progress in the company’s largest clean energy acquisition effort to date. The investments — along with the advancement of the next round of clean energy projects — are part of a long-term strategy to keep power safe, affordable, reliable and increasingly clean for Oregon customers.
As part of its Integrated Resource Planning process, PGE plans years ahead to make sure customers have the energy they need. This includes securing new renewable resources, adding battery storage to support reliability, strengthening the grid, and capturing federal tax incentives that help reduce customer costs.
A multi-pronged process to identify the least-cost, least-risk projects
PGE is executing a multi-pronged procurement strategy to secure the least-cost, least-risk resources for customers while capturing federal tax credits that directly support affordability. This strategy includes the 2023 All-Source Request for Proposals (RFP), power purchase agreement (PPA) procurement efforts, and the 2025 RFP — together representing the largest clean energy acquisition effort in company history.
These processes are overseen by the Oregon Public Utility Commission (OPUC), which ensures that all bids are evaluated through a fair, impartial, and transparent review process.
“Every step in this process is about delivering the most value for our customers,” said John McFarland, Chief Commercial, Customer and Digital Solutions Officer. “By capturing federal tax credits and building the right mix of company-owned and partner projects, we’re adding the energy Oregon needs in a way that supports reliability and keeps long-term costs as low as possible.”
More than 1,000 MW of new clean energy and battery storage
With contract negotiations complete, PGE and third-party developers will begin construction planning for new clean energy and battery storage projects totaling 1015 MW (41% utility-owned and 59% Power Purchase Agreements). These resources are expected to begin serving customers in 2027 and 2028.
Two projects are advancing into development, using existing transmission and interconnection to reduce costs:
Biglow Optimization — Sherman County, Ore.
125 MW solar and 125 MW battery storage
Target operation: late 2027
PGE-owned; approx. $540 million investment
Wheatridge Expansion — Morrow County, Ore.
240 MW solar and 125 MW battery storage
Target operation: late 2027
Joint ownership with a third party; PGE owns 110 MW solar and 60 MW storage; approx. $490 million investment
PGE also secured power purchase agreements, pending regulatory approval, for two battery storage projects with a total capacity of 400 MW:
Meadowlark Battery — Washington County, Ore.
200 MW battery storage
Target operation: late 2027, pending OPUC approval
Third-party owned; PGE to serve customers through a long-term power purchase agreement.
Nottingham Battery — Washington County, Ore.
200 MW battery storage
Target operation: 2028, pending OPUC approval
Third-party owned; PGE to serve customers through a long-term power purchase agreement.
These projects add flexible, fast-responding resources that help balance renewable energy and strengthen reliability during high demand periods and extreme weather.
Looking ahead: PGE files Final Shortlist for 2025 RFP
To secure the next round of resources to meet customers’ needs, PGE has submitted the Final Shortlist for its 2025 All-Source RFP, which includes 12 non-emitting projects — wind, solar and battery storage with a combination of power purchase agreements and utility ownership.
PGE is targeting the end of Q3 2026 to secure agreements for approximately 2,500 MW of additional clean energy and storage. These projects are planned for service in 2028 and 2029.
