Bradley Lake Hydroelectric Project

Project Overview

The Bradley Lake hydroelectric project was constructed by the Alaska Power Authority on the Kenai Peninsula near Homer, Alaska. The Alaska legislature appropriated $168 million for what was estimated to be a $245 million project. The project, which cost over $300 million (including reserve fund balances, of $479 million 2007 dollars), went into commercial operation in 1991. The project includes a concrete-faced and rock-filled gravity dam, 610 foot long, 125 foot high, and a 3.5-mile power tunnel and steel-lined penstock. The project transmits power to the state’s main grid via two parallel 20-mile transmission lines. Homer Electric Association under contract with AEA now operates the project. Bradley Lake serves Alaska’s Railbelt from Homer to Fairbanks as well as the Delta Junction area.
