Portland General Electric Enhances Energy Resilience with New Battery Storage Facilities
Portland General Electric (PGE) marks a significant advancement in energy management by successfully launching three new utility-scale battery energy storage systems in the Portland metro area. These installations, which collectively add 475 megawatts (MW) and over 1.9 gigawatt hours (GWh) of dispatchable capacity, are strategically located in North Portland, Troutdale, and Hillsboro. With the ability to supply power to approximately 300,000 homes for up to four hours during peak demand, these systems play a crucial role in balancing energy supply and demand in a region that increasingly relies on renewable energy sources.
The new lithium-ion battery systems enhance PGE’s generation portfolio, providing greater flexibility and reliability in electricity supply. Darrington Outama, PGE’s Senior Director of Energy Supply, highlights that these facilities are pivotal in stabilizing energy delivery, especially during times of adverse weather or unexpected demand surges. By integrating these battery systems, PGE not only bolsters its capacity to deliver consistent power but also strategically reduces its dependence on expensive short-term electricity purchases. This move is expected to mitigate price volatility for consumers, ultimately contributing to more predictable and stable energy costs.
The operational launch of two of these facilities, Seaside and Sundial, was developed in partnership with Eolian, L.P., following PGE's 2021 All-Source Request for Proposals. The Seaside facility, located in North Portland, began commercial operations in July 2025, while the Sundial facility in Troutdale commenced in December 2024. In addition to these, PGE's own Constable facility, which adds another 75 MW of capacity, further strengthens the region's energy storage capabilities. Collectively, these advancements underscore PGE's commitment to enhancing energy reliability while promoting sustainability and supporting the integration of renewable energy sources like wind and solar.
In light of these developments, PGE's investment in battery storage technology aligns with broader industry trends focusing on renewable energy integration and grid resilience. As energy demands continue to evolve, the deployment of such advanced storage solutions becomes increasingly critical for utility companies. The successful implementation of these facilities illustrates PGE's proactive approach to meeting future energy challenges while maintaining a commitment to environmental sustainability.
Overall, PGE's new battery storage systems represent a pivotal step forward in the utility's mission to provide reliable, affordable, and sustainable energy solutions to its customers. As the energy landscape continues to shift, the role of innovative technologies like battery storage will be essential in ensuring a stable energy future for the Portland metro area and beyond.
