The Swan Lake hydroelectric plant is located in Ketchikan Gateway County, Alaska. It has a total capacity of 22.6 MW across two generators, and it began operating in 1984. The primary fuel source is water (WAT), and the plant utilizes conventional hydroelectric technology. The operator is Southeast Alaska Power Agency.
Swan Lake's latest annual generation was 75,471 MWh, resulting in a capacity factor of 38.1%. The plant is the sixth-largest of 29 hydroelectric facilities in Alaska, and it ranks 464th out of 1464 nationally. The balancing authority is listed as "No BA," indicating it may operate outside of a formal independent system operator (ISO) or regional transmission organization (RTO) market.

This plant is in a bilateral market territory without organized wholesale pricing. Nodal pricing data is not 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.
