Read more on WikipediaLocated in Skamania County, Washington, the Swift 1 hydroelectric plant has a total capacity of 240 MW across three generators. The plant began operating in 1958 and is owned by Berkshire Hathaway, with PacifiCorp as the operator. As a conventional hydroelectric facility, its primary fuel source is water (WAT). Swift 1 operates within the PacifiCorp - West balancing authority and the Western Electricity Coordinating Council (WECC) NERC region.
In the most recent year of reported generation, Swift 1 produced 534,663 MWh of electricity, achieving a capacity factor of 25.3%. The plant's installed cost was $716.05 per kW, and it has a power purchase agreement (PPA) price of $10.78 per MWh. Swift 1 is ranked as the 15th largest power plant out of 23 in Washington state, and 84th out of 194 nationally. Financial data for the plant is available from FERC and FERC EQRs.

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.
