Take Action

Where to start

What changed in August 2026. Jupiter Power withdrew both of its King County permits and will seek approval from the state instead, through the Energy Facility Site Evaluation Council (EFSEC). The 14-day county comment window this page used to prepare people for will not open. No state application has been filed yet. The work below is still worth doing, and some of it matters more now, not less. See the EFSEC process for what the change means.

If you do one thing, sign up for updates. We’ll alert you when Jupiter files with the state, when comment opportunities open, and when community meetings are scheduled.

After that:

  1. Now: Start preparing your comment on the project itself. EFSEC runs its own comment opportunities once an application is filed, and the substance of a good comment does not change with the venue. Read our comment guide and pick the one topic where you have knowledge or standing. The Sources and Evidence library has the primary sources to cite.
  2. Then: If you have energy beyond your own comment, the targeted asks below cover the gaps that remain.

What the institutions have already done

The groundwork phase of this effort asked local institutions to engage. They have:

See the updates timeline for all of it. What remains is below.

What you can do now

Write to the Snoqualmie City Council

The City has done the heavy lifting. Three asks remain:

Email: councilmembers@snoqualmiewa.gov

Write to Snoqualmie Valley Hospital

Snoqualmie Valley Hospital is the closest emergency facility to the project site. Hydrogen fluoride exposure causes deep tissue burns and pulmonary edema that require specialized treatment. The hospital would receive casualties from an HF release event. It has not yet taken a public position.

Email Ken Rudberg (Director of Quality, Risk & Compliance): kenr@snoqualmiehospital.org

Ask them to:

If you’re on a private well

The project site is surrounded by dozens of private domestic wells, with the highest concentration in the unincorporated residential area downhill to the southwest (31 water wells in that quarter section alone). The City of Snoqualmie also draws its municipal water from valley groundwater wells. Contaminated firefighting runoff from a lithium-ion battery fire (heavy metals, fluoride compounds, electrolyte) could migrate through soil to groundwater. No hydrogeologic assessment has been submitted for this project.

If you’re on a private well near the project site, you have a direct stake in the environmental review. Your comment about groundwater risk carries weight that a general safety concern does not. See our groundwater analysis for the data, including well locations, depth ranges, and the Sumner precedent where a public water well on a BESS project parcel triggered the strongest groundwater conditions in any Washington BESS project.

When the comment window opens, submit a comment identifying your well and asking that a hydrogeologic assessment be required before the project is certified.

Write to local fire agencies

The fire authorities are already on the record: Fire District 38’s elected board opposes the siting, and Chief Aho has stated EF&R “cannot confirm” preparedness. The remaining work is converting those positions into the state’s decision record:

King County Fire Marshal Eric Urban: eric.urban@kingcounty.gov

Eastside Fire & Rescue Chief Will Aho: waho@esf-r.org

City of Snoqualmie Fire Department Chief Mike Bailey: mbailey@snoqualmiewa.gov


When the state process opens

Jupiter has said it is going to the state. It has not filed yet. We check EFSEC’s records daily and will email the list the day a filing appears. Sign up for updates and you don’t have to track it yourself.

Prepare your comment now

The venue changed. The substance did not. The site conditions, the fire and emissions questions, the water supply problem, the groundwater and stream issues, and the proximity to homes and schools are all the same facts, and they will be argued to EFSEC instead of to King County.

Read our guide on how to write an effective comment. It covers the legal standard, the checklist elements relevant to this project, what makes a comment effective, and what to avoid. You don’t need to cover everything. One well-supported comment on a single topic is more valuable than a vague letter touching all of them. Start now so you are ready when the window opens rather than starting from scratch inside it.

Push the institutions above to participate

The City, the school district, and the fire agencies have all taken public positions. Those positions were built for a county proceeding that no longer exists, and they do not carry over on their own. Ask each to bring what it has already said into the state process, through comment, through the consistency hearing on local land-use codes, or through formal party status. Institutional participation carries weight that individual letters cannot, and a position stated elsewhere (a WUTC filing, a board resolution, a press statement) reaches the state record only if someone puts it there.


Get informed

Understanding the permitting process, the technology, the fire risk, the site and environment, and what we’re asking for makes your voice more effective when the time comes.
