Key documents

These are the most significant recorded instruments for understanding the BESS project’s land control, constraints, and interconnection challenges.

Jupiter Power land agreements:

PSE corridor, annexation, and interconnection constraints:

Corporate structure: Jupiter Power uses two entities. The main parcel was acquired through Snoqualmie Energy Storage LLC (sole member: Accelergen Development LLC). All later options were through Cascadia Ridge Resiliency LLC (1108 Lavaca St, Austin TX). Both trace back to Jupiter Power.

Parcel 3624079039 — Main project site (~25.3 ac)

Owner: Snoqualmie 55 LLC (Conner Homes/Burnstead entity) Zoning: UR (Unincorporated Rural) Documents found: 6

Parcel 3624079093 — Nause Lot 4 (~5.0 ac, vacant)

Owner: Nause LLC Zoning: UR Legal: Lot 4, KC Short Plat 675001 Note: Vacant land with transmission line easement. Not listed in the original permit application but under option since March 2024. Likely intended for access, buffer, or additional infrastructure. Documents found: 10

Parcel 3624079100 — Nause Lot 3 (~5.0 ac)

Owner: Nause LLC (same as parcel 3624079093) Zoning: UR Legal: Lot 3, KC Short Plat 675001 Known pre-LandmarkWeb document: A 1969 mineral reservation severed subsurface rights from the surface ownership. The current holder of these subsurface rights is unknown. This document predates LandmarkWeb and has not been retrieved. Documents found: 16

Parcel 3624079101 — Landgraf residential property (~5.0 ac)

Owner: Heather Landgraf (single person, as of Jan 2025 divorce transfer) Address: 35717 SE 82nd Street, Snoqualmie WA 98065 Zoning: UR Legal: Lot 1, KC Short Plat 675002 Documents found: 16

This parcel has the most complex recorded history of any project parcel. PSE used eminent domain in 2010 to acquire perpetual utility easements here. The resulting 300-foot construction setback from PSE facilities, combined with the 220-foot BPA corridor, significantly constrains the usable area.

Parcel 3624079103 — Arnold residential property (~5.0 ac)

Owner: Daniel and Jenny Arnold Zoning: UR Documents found: 7

PSE Corridor Parcels

PSE owns five parcels forming the transmission corridor adjacent to the BESS site, including the Mt. Si substation: 3624079030, 3624079091, 3624079098, 3624079099, and 3624079102. The City of Snoqualmie holds perpetual environmental covenants across all of these parcels (see key documents above). No Jupiter Power agreements are recorded on any of these parcels; access is likely governed by the PSE tolling agreement (UTC Docket UE-240532).

The Pre-Annexation Development Agreement (PADA, Rec# 20110202001508) is the foundational document governing these parcels. It was executed between PSE and the City of Snoqualmie in 2010 to authorize annexation and development of the Mount Si Substation. Key provisions:

• Parcel 9102 is designated a “Future Development Area” requiring a full-scope Annexation Implementation Plan (AIP) before any utility connections, short plat, subdivision, or other development
• Development is limited to the substation, transmission lines, and related electrical utility uses
• The PAUE (Public Agency or Utility Exception, SMC 19.12.030C) is required for any development altering wetland or stream buffer areas
• Section 6.10 specifically limits parcels 9098 and 9099 to transmission line construction, with King County as the permitting authority
• A Mitigated Determination of Non-Significance (MDNS) was issued February 12, 2010 for the substation and transmission lines
• Exhibit 12 contains the Covenant and Grant of Easement (recorded separately as Rec# 20110429001446)

Parcel 3624079030 — PSE property (~5.0 ac)

Owner: Puget Sound Energy Inc. Legal: Lot 3, KC Short Plat 675002 Documents found: 4

Parcel 3624079091 — PSE substation parcel (~19.4 ac)

Owner: Puget Sound Energy Inc. Legal: N half of SW 1/4 of NW 1/4, Section 36, T24N, R7E (Tax Account 362407-9091-04) Documents found: 7

Parcel 3624079098 — PSE corridor, western portion

Owner: Puget Sound Energy Inc. Documents found: 5

This parcel is part of the PSE transmission corridor. The PADA (Section 6.10) specifically addresses parcels 9098 and 9099 as sites for transmission line construction, with King County (not the City of Snoqualmie) as the permitting authority since these parcels were not being annexed.

Parcel 3624079099 — PSE corridor, Baisden parcel

Owner: Puget Sound Energy Inc. Legal: N half of NW 1/4 of NW 1/4, Section 36, T24N, R7E (also known as Lot 2 of KC Short Plat 675001) Documents found: 7

This parcel was originally owned by the Baisden family, sold to Weyerhaeuser Real Estate Co. in 1995, and subsequently acquired by PSE. The PADA addresses this parcel alongside 9098 for transmission line construction.

Parcel 3624079102 — PSE “Future Development Area”

Owner: Puget Sound Energy Inc. Legal: Portions of Lots 1 and 2, KC Short Plat 675001, and Lot 2, KC Short Plat 675002 Documents found: 8

The PADA designates this parcel as a “Future Development Area” (Exhibit 6), subject to a zoning condition that requires completion of a full-scope Annexation Implementation Plan (Section 4.3) before any new utility connections, short plat, subdivision, or other development. Development on this parcel vests to whatever regulations are in effect when a complete application is filed, not to the PADA-era standards.
