On March 17, 2026, Jupiter Power will hold a community meeting for Snoqualmie residents at the Club at Snoqualmie Ridge from 5 – 7:30 pm to discuss the company’s proposed Cascadia Ridge Battery Energy Storage project. The roughly 45-acre project site is in unincorporated King County on land designated as Snoqualmie’s Urban Growth Area by the Washington State Growth Management Act.
The project is currently going through the permitting and review process with King County. As the project site lies just outside Snoqualmie city limits, King County has permitting authority, including all land use review, environmental analysis, and public hearings.
In September 2024, the King County Council approved legislation proposed by Councilmember Sarah Perry, who represents the Snoqualmie Valley, that established the regulatory framework around how and where battery energy storage systems can be set up in the county.
According to the proposed Cascadia Ridge Energy Storage project website, the facility would include lithium-ion batteries, battery energy storage system containers, thermal control systems, fire detection and suppression systems, electric control equipment, and more.
“Cascadia Ridge Resiliency is a project that stores energy and then puts energy back into the grid at times of high demand. The project utilizes batteries but does not “store” batteries on the site for collection, resale or recycling,” said Jupiter Power Communications and Public Affairs Maggie Glynn. “Because battery energy storage systems can soak up energy at times of low demand, when electricity is cheap, and put it back onto the grid at times of high demand, when energy is expensive, batteries can support lower costs for electric consumers. Cascadia Ridge Resiliency can respond within fractions of a second to electric grid needs and can support a reliable electric grid.”
Some Snoqualmie residents are expressing concerns, though, speaking out during the March 9 City Council meeting. Concerns cited by residents include a location near densely populated neighborhoods and a city park, fire risk, noise, air and light pollution. Concerned residents have also asked others to write to King County Councilmember Sarah Perry opposing the project’s location.
According to the City of Snoqualmie Comprehensive Plan, the proposed project site is located within its Urban Growth Area in an area sometimes referred to as Snoqualmie Hills West. If approved by King County, the project would be located near Fisher Creek Park, the Woody Creek and Braeburn neighborhoods and the Snoqualmie Ridge Business Park.
Urban Growth Areas are designated by the State Growth Management Act as land areas in which cities can legally plan for and annex for growth. Snoqualmie’s Comprehensive Plan Future Land Use Area Map (see map above) does not appear to align with Jupiter Power’s project in the proposed location. Instead, Snoqualmie’s Comprehensive Plan outlines uses for the proposed project site as “master-planned business park” and “innovative mixed use.” The city’s future land use map does include a utility park usage – which includes power generation – but sites that usage near the city’s sewer treatment plant off Millpond Road near SR 202.
Jupiter Power says safety is a top priority for the project, and it “is being designed with knowledge of current and pending fire code improvements in order to minimize fire risk.” The design includes internal setbacks between batteries to prevent the spread of any fire from one battery container to another and setbacks from any potential wildfire area through a perimeter of cleared area.
Flynn said, “The intent of the fire safety design is that in the event of an incident, any fire would remain a very small fire and is intended to have no impact outside the property boundaries.”
According to Jupiter Power, the project will support significant new revenue for local schools and tax districts. Jupiter Power projects total annual tax payments in the 3rd through 12th year of the project to be between $783,000 and $1,130,000.
Snoqualmie City Councilmember Dan Murphy does not support the project’s proposed location, stating: “This is really simple — industrial battery storage doesn’t belong in the middle of a neighborhood. I’ve spoken with many residents, and the message is loud and clear: a 42-acre lithium battery site steps from homes, parks, businesses, and fish-bearing streams is an unacceptable risk. I encourage community members to educate themselves on this proposal and engage in all public input opportunities, including this Tuesday at 5 pm.”
Via a news release, the City of Snoqualmie encouraged interested residents to engage directly in King County’s project review process by:
- Attending Jupiter Power’s community event: Tuesday, March 17, 2026 5:00–7:30 pm | The Club at Snoqualmie Ridge.
- Submitting comments and participating in King County public hearings
- Contacting King County Councilmember Sarah Perry, who represents the Snoqualmie Valley: sarah.perry@kingcounty.gov.
[The City of Snoqualmie was asked for a comment about the project’s alignment with its Comprehensive Plan, but responded that it did not have a comment at this time.]
