At its board meeting in Ketchikan April 28, Southeast Alaska Power Agency agreed to look into the feasibility of putting in a third generating unit at the Tyee Lake hydroelectric facility.

The proposal was put forward by board members representing Wrangell and Petersburg, whose communities Tyee predominantly powers.

Operating since 1984, the Tyee hydro facility uses water from a natural lake, which is funneled into a drop shaft feeding two generating units that together generate 25 megawatts of power. In the original construction, the foundation for an eventual third unit was included.
