Glacier Battery Storage is a 2 MW battery energy storage system located in Whatcom County, Washington. The plant began operating in 2016 and has one generator. It is owned by Puget Holdings and operated by Puget Sound Energy Inc. The primary fuel source is electricity (MWH), which is used to charge the lithium-ion batteries. The battery system has a total storage capacity of 4.4 MWh, providing a duration of 2.2 hours at its full 2 MW output.
The facility operates within the Puget Sound Energy balancing authority and the Western Electricity Coordinating Council (WECC) NERC region. Glacier Battery Storage is ranked as the 9th largest battery storage plant in Washington and 1138th nationally, out of 10 and 1205 plants respectively.

Capacity Factor
Positive values indicate net discharge (generation exceeds station load). Negative values indicate net charging. Pure battery storage plants are typically net negative due to round-trip efficiency losses.

This plant's balancing authority participates in CAISO's Western Energy Imbalance Market (WEIM). Direct nodal pricing data is not yet available.
No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
