Welcome to the Southeast Alaska Power Agency’s (SEAPA) public site for the Tyee Lake Third Turbine License Amendment Project

This page and links serve as an information source for people interested in learning more about the Tyee Third Turbine License Amendment Project and the license amendment process

THE PROJECT

The Southeast Alaska Power Agency (SEAPA) operates the Tyee Lake Hydroelectric Project (Project) located on Tyee Creek approximately 40 miles southeast of Wrangell, Alaska under a license issued by the Federal Energy Regulatory Commission (FERC), FERC Project No. P-3015. The Project is located in a remote area of Southeast Alaska on federal, state, borough and private lands. The Project, together with the Swan Lake Hydroelectric Project via the Swan-Tyee Intertie serves the remote communities of Ketchikan, Wrangell, and Petersburg, Alaska.

The Tyee Lake Project was designed and constructed with provisions to add a third generating unit. The third turbine (and generator) would increase the Project’s installed capacity by 50 percent (12.5MVA). Adding the third turbine requires a capacity license amendment.

THE LICENSE AMENDMENT PROCESS

SEAPA will use the required FERC process for filing a license amendment, which affords an opportunity to evaluate all resources potentially affected by an amendment to the operation of the Project. The process begins with early identification and resolution of studies to fill information gaps to avoid additional studies once the application is filed with FERC. The process encourages collaboration and integrates stakeholders in the license amendment process, including state and federal resource agencies, non-governmental organizations (NGOs), applicable Native American tribes, and members of the public.
