Cold Climate Problems of a Micro- Hydroelectric Development on
Abstract—A micro-scale hydroelectric plant has been proposed for Crow Creek, a mountain stream located in an off-grid area of the Chugach Range near Girdwood, Alaska. The run-of-river plant design has an expected generation capacity of 125 kW, and could power up to thirty homes and displace pollutin...
