Seattle Times: Washington’s Clean Energy Future Depends on Battery Storage

A new Seattle Times opinion piece makes a clear case for why battery energy storage needs to become a more common part of Washington’s electric grid.

The article lays out the challenge facing the state: Washington is working to reduce reliance on fossil fuels at the same time electricity demand is growing. More people are driving electric vehicles. More homes are using heat pumps. More communities are relying on a grid that has to stay balanced every minute of every day.

That shift will require more than policy goals. It will require infrastructure.

The Seattle Times points to battery energy storage as one of the tools Washington will need to keep the grid reliable as more wind and solar power come online. These systems store electricity when power is available and deliver it back to the grid when demand rises, helping utilities manage the daily peaks and valleys that come with powering homes, businesses, schools, and essential services.

The need is especially important in Western Washington. As the piece explains, much of the state’s new wind and solar generation is located east of the Cascades, while many of the customers who need that power live west of the mountains. Transmission constraints make it harder to move electricity where it is needed, and major transmission upgrades can take years to plan, permit, and build.

That is why battery storage closer to where people live and use electricity is becoming an important part of Washington’s reliability conversation.

The article also addresses questions that have been raised around battery storage projects, including fire safety. Those questions deserve serious answers, and the evidence around modern battery storage is important. On our Fast Facts page, we’ve collected resources from fire safety authorities, state agencies, independent researchers, and environmental testing reports that help explain how modern battery storage is designed, regulated, and reviewed. The data also shows real progress: according to the Electric Power Research Institute, the failure rate for battery storage systems dropped by 99% from 2018 to 2025 as lessons from earlier incidents were incorporated into newer designs, safety systems, and best practices.

That context matters. Battery storage is not unregulated technology being dropped into communities without standards or oversight. It is increasingly studied, regulated, and improved infrastructure that utilities across the country are using to support a more reliable grid.

Projects like the proposed Cascadia Ridge Resiliency Energy Storage Project are part of that larger energy future. The project would add 130 megawatts of storage capacity in Western Washington, providing an important reliability resource in a region where electricity demand is growing and the grid needs more flexibility.

Keep The Lights On! Washington was formed to help bring more voices into this conversation and ensure communities have access to clear, factual information about battery storage, grid reliability, and Washington’s growing energy needs. The coalition includes clean energy advocates, labor and workforce organizations, business voices, and community members who support practical energy infrastructure solutions that can help strengthen the grid as demand grows.

As the Seattle Times makes clear, Washington’s clean energy transition will not happen through policy goals alone. It will require practical infrastructure, thoughtful siting, strong safety standards, and a willingness to build the energy resources communities will depend on in the years ahead.
