PGE closes out 2021 RFP with procurement of 75-MW battery storage project
May 31, 2023
Portland, Ore. — Portland General Electric Company (NYSE: POR) today announced the procurement of the Evergreen battery energy storage system, a new 75-MW facility to be located at a soon-to-be-constructed substation in Hillsboro, Oregon. This battery project, owned by PGE and built by Mortenson, is expected to begin service in 2024, adding critical non-emitting dispatchable capacity to Oregon’s clean energy transition.
This announcement builds on PGE’s recent procurement of 400 MW of battery projects 
– the second largest commitment to standalone energy storage made by any U.S. utility to date. Battery systems offer a number of grid benefits, providing flexibility and consistency as PGE integrates more intermittent renewable resources. Stored energy can be reliably deployed within seconds to customers during extreme weather events or times of high demand, reducing dependence on energy markets and fossil fuel generation.
“Mortenson is proud to be helping PGE build a clean energy future for their customers by adding energy storage to the grid” said Brent Bergland, vice president, project development at Mortenson. “Projects like Evergreen enable greater use of renewable energy and are a powerful way to help decarbonize our planet, and our energy storage team is excited to engineer, procure, construct and deliver a complete world-class facility to PGE.”
The Evergreen facility represents the final procurement from PGE’s 2021 Request for Proposal (RFP), which resulted in landmark projects including the 311 MW Clearwater Wind Farm, scheduled to begin operations by the end of 2023.
“From Clearwater to Evergreen, Portland General Electric is building Oregon’s clean energy future,” said Maria Pope, PGE President & CEO. “Our wind, solar, hydro and battery storage facilities work together as part of a resilient grid to provide safe and reliable energy while helping us to manage costs.”
Earlier this month, PGE filed its 2023 Draft RFP with the Oregon Public Utility Commission, initiating the process to bring new clean energy resources online. PGE expects to seek bids for additional non-emitting dispatchable capacity resources, like batteries, which will continue to play a growing role in the utility’s portfolio, as well as renewable generation projects, such as wind and solar farms. Most importantly, the draft RFP aims to maximize reliability and customer value by seeking to procure projects that can leverage Bonneville Power Administration’s long-term transmission capacity to deliver energy to PGE customers.
Together, these actions demonstrate PGE’s continued focus on decarbonization while prioritizing reliability and managing costs for customers. To get involved visit portlandgeneral.com/rfp.
