119th largest plant in Alaska · 11440th nationally
Newhalen is a hydroelectric power plant in Alaska with a nameplate capacity of 1.7 MW. It generates roughly 3.2k MWh per year — enough to power about 302 average U.S. homes.
Its capacity factor of 21% reflects intermittent or peaking operation. At 28 lb CO₂/MWh, its emission rate sits below the national grid average of roughly 800 lb/MWh.

Hydroelectric plants spin turbines using falling or flowing water — typically from a dam-impounded reservoir. They are dispatchable, long-lived, and emission-free at the point of generation, though large reservoirs can disrupt rivers and ecosystems and methane can be released from flooded vegetation.
