The Penstemon Solar Project is a 5 MW solar photovoltaic power plant located in Kittitas County, Washington. The plant began operating in 2022 and is owned and operated by Greenbacker Renewable Energy Corporation. It utilizes single-axis tracking technology to maximize solar energy capture. The plant is connected to the grid and falls under the balancing authority of Puget Sound Energy (PSE) within the Western Electricity Coordinating Council (WECC) NERC region.
In its most recent year of operation, the Penstemon Solar Project generated 10,725 MWh of electricity, achieving a capacity factor of 24.4%. While a relatively small facility, it contributes to Washington's renewable energy portfolio. Penstemon Solar Project is ranked as the 10th largest solar plant in Washington state, and 2482nd nationally out of 7108 plants. The plant consists of a single generator using SUN as its primary fuel.

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.
