Owner data does not fully agree across sources.
EIA typically reports the operating utility, while GEM resolves to the financial owner or parent corporation. Both can be correct.

The Snettisham hydroelectric power plant is a 78 MW power plant located 28 miles south of central Juneau, Alaska and accessible only by boat or seaplane. The power plant is fed by two lakes that are tapped from below, negating the need for a traditional dam. As of 2020 it supplies 65% of the electricity for Alaska Electric Light & Power. It is connected to Juneau by a 44-mile transmission line.

The plant, which began operating in 1973, has a total capacity of 78.2 MW derived from three generators utilizing conventional hydroelectric technology. It is owned and operated by Alaska Electric Light & Power Co. The primary fuel source for the plant is water (WAT).
In the most recent year of reported data, Snettisham generated 332,682 MWh of electricity, achieving a capacity factor of 48.5%. Snettisham is the second-largest of 29 power plants in Alaska, and ranks 229th out of 1464 plants nationally.

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.

Juneau businesses and nonprofits are contesting AIDEA's plan to sell renewable energy credits generated by Snettisham, which they argue would strip Juneau of its 100% renewable electricity designation.
