Storing all that
Good Energy
As we shift toward using more wind and solar power, large-scale batteries are essential. They help make our energy system more reliable by storing extra power from any generation source and delivering it to customers when it's needed most.
Why we need energy storage
Renewable energy like wind and solar isn’t always available when people need power. Wind often produces energy at night, and solar peaks midday—but we usually use the most electricity in the evening. Large-scale battery systems add flexibility to the grid by storing extra low-cost energy when demand is low and releasing it when it's high.
They can also be deployed quickly to fill energy gaps—like during extreme weather or sudden changes in supply. That can mean fewer disruptions and more reliable service for customers.
Three locations
As of June 2025, the 475 megawatts of battery storage procured in PGE's 2021 Request for Proposal are now online and delivering power to the grid. These projects were announced in April 2023 and are located in North Portland, Troutdale, and Hillsboro.
One powerful result
Collectively, 475 MW can provide enough electricity to power about 300,000 homes for four hours during times of peak demand.
Grid support = More reliability + Savings
Storing extra energy
By storing energy from sources like wind and solar, batteries help reduce our reliance on fossil fuels and make the most out of our existing generation resources.
Delivering power when it’s needed
When power is limited due to weather or unexpected interruptions, PGE can dispatch stored energy directly to the grid.
Keeping energy reliable and affordable
Battery storage allows PGE to store extra energy when prices are low and release it when prices are high, helping to stabilize energy costs and reduce price volatility for customers.
Smaller systems add up to large results
Many of our residential customers can use their home battery storage systems (often combined with rooftop solar) to connect to the grid. These smaller batteries work together to deliver the same reliability services to the grid as large-scale battery systems. PGE programs like our Smart Battery pilot and Peak Time Rebates not only help keep the grid stable, but they also provide some financial incentives to customers who choose to participate in them.

Current & future battery projects
To support Oregon’s transition to clean energy and meet growing energy needs, PGE is maximizing the impact of federal tax credits for new renewable energy and battery projects through its Request for Proposal process. Currently, PGE has 492 MW of battery storage capacity and is actively working to expand this portfolio to ensure reliable energy at the lowest cost possible for customers.

Current & future battery projects
At PGE, we’re committed to powering a clean energy future with reliable service our customers can count on. To meet growing energy needs and keep prices as low as possible, we're planning several new projects that will add even more renewable energy and battery storage over the next few years to serve customers. These investments will strengthen the grid, help keep prices as low as possible, and support Oregon’s transition to a more sustainable future.
