FAQs
Where will the project be located?
Cascadia Ridge Energy Storage will be located across Snoqualmie Pkwy from Snoqualmie Ridge within roughly 45 acres of land just south of the City of Snoqualmie’s Fisher Creek Park in unincorporated King County. The generation tie-line will run south across PSE property andinterconnect to the abutting
Mt. Si substation.
What will be located at the facility?
The Project will include the following equipment and associated facilities:
Lithium-ion batteries
Battery energy storage system containers
Thermal management systems for temperature control
Fire detection and suppression systems
Electric control equipment
Power Conversion Systems (Inverters / transformers)
Step-up transformer and project substation, including lightning protection, a control enclosure, and internal fencing
Communications equipment
A perimeter fence and security gate
115kV generator tie-line and utility interconnection
Other facilities required for construction and operation of the Energy Storage Facility
What will the facility look like?
The Project facilities will sit on approximately 45 acres across five project parcels. The site is naturally setback from public streets and trafficked areas, and the project will maintain a significant tree buffer. From any public vantage point it is unlikely that the Project will be seen beyond the tree buffer. The Project components themselves will be enclosed by a fence. The Project will not be visible from any nearby residences.
Is battery energy storage safe?
Safety is our top priority during construction, operations, and for the life of the battery. Project operations will not directly produce fumes, pollution, odor, dust, or other offsite impacts that would result in health impacts to those nearby.
Jupiter Power is always evaluating equipment and the newest industry developments for preventative maintenance for safe battery energy storage facilities. We will also train all relevant first and secondary responders in the community, on an ongoing basis. Each battery cell within the building are individually monitored, providing constant, 24/7 oversight capability over every component of the Project. Each building is equipped with an integrated system of sensors, alarms, and fire suppression systems. The operational management systems will be designed, installed, and operated according to national Fire Code standards and regulations. All Jupiter Power battery systems are fire safety tested according to strict Underwriters Laboratory protocols.
Safe operations are enhanced by design parameters; state-of-the-art technology for monitoring,alarm, and fire suppression systems; and clear, open, and regular communication with firstresponders. To that end, we will work closely with the local first responders at the City andCounty level, along with other local stakeholders throughout the project design process and lookforward to continuing that cooperation throughout the operating project life.
How will this project benefit the community?
The Project will benefit residents and businesses by improving the power grid and supporting the local economy.
Battery energy storage is a proven technology that provides increased power to the grid and other grid management capabilities, like grid balancing through instantaneous battery energy storage response. With these capabilities, the Project will deliver more reliable power for residents and businesses—all without building new transmission infrastructure, which ratepayers would have to fund.
The Project would represent a significant financial investment in King County. The Project will generate local tax revenue for the area for the life of the project. It will also create construction jobs and local sales tax benefits during construction.
When will construction start?
We're projecting to start construction in 2027 and be in service by late-2028.
