Portland General Electric recently 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.
With contract negotiations complete, PGE and third-party developers will begin construction planning for new clean energy and battery storage projects totaling 1015 MW (42% utility-owned and 58% 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 in Sherman County, OR, and Wheatridge Expansion, Morrow County, OR. The two projects have target operation dates of late 2027, have a combined 265 MW of solar, and each have 125 MW of battery storage.
The power purchase agreements, pending regulatory approval, are for two battery storage projects: Meadowlark Battery, Washington County, OR, and Nottingham Battery, Washington County, OR. Each battery project will have 200 MW and be third-party owned.
These projects add flexible, fast-responding resources that help balance renewable energy and strengthen reliability during high demand periods and extreme weather.
