Description

The original preliminary permit for this project expired in March 2013.

The project tidal barrage project will be located on Gastineau Channel, in the City and Borough of Juneau, Alaska.

The proposed project will either attach turbines to the underside of an existing Coast Guard dock, or anchor the turbines to the bottom of the channel, and would consist of: (1) an existing approximately 100-foot-long by 30-foot wide U.S. Coast Guard dock on the Gastineau Channel connected to the shore by an approximately 550 foot-long boardwalk; (2) twenty 20-kilowatt (kW) Red Hawk in-stream turbine modules anchored to the bottom of the channel or attached to the underside of a pivoting t-dock with a total generating capacity of 400 kW; (3) one or more clusters of Tidal In-Stream Energy Conversion Devices (TISEC device) to transmit the electricity from the turbines to the underwater transmission line; (4) an approximately 600-foot-long, 480-volt underwater transmission line connecting the TISEC device to an existing above-ground local distribution system; and (5) appurtenant facilities. The project will have an estimated average annual generation of approximately 1,226 megawatt-hours.
