Project Description
| The Projects are part of a proposed system of hydroelectric projects and new and existing transmission segments collectively referred to as the Thomas Bay Energy Development (TBED). The TBED is intended to supply electricity generated in Alaska to markets in Southeast Alaska, Canada, and the continental United States. This generation-transmission system has been under evaluation for several years, resulting in a complex array of components and interactions among developers, the state of Alaska, and governments and utilities of the US and Canada. |  |
The two proposed hydroelectric projects utilize storage in lake systems which drain into Thomas Bay, near Petersburg, Alaska. The proposed projects are:
Cascade Creek Project (FERC No. P-12495-002)
The Cascade Creek Project would be located approximately 15 miles north of Petersburg, Alaska on Swan Lake and Cascade Creek. The general project configuration would involve a lake siphon in Swan Lake, a power conduit, and a powerhouse/switchyard. The primary transmission line would be a combination of overhead and submarine segments from the Cascade Creek Project switchyard to Petersburg. Learn more.
Ruth Lake Project (FERC No. P-12619)
The Ruth Lake Project would be located approximately 2 miles south of the proposed Cascade Creek Project. The general project configuration would involve either a lake-tap in Ruth Lake or a dam as high as 157 feet, and a powerhouse/switchyard. From the powerhouse, project energy would interconnect with the Cascade Creek Project primary transmission line. Learn more.
