About

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.
