Koma Kulshan Project

The Koma Kulshan Project is a 13.3 MW run-of-the-river hydroelectric generation facility on the slopes of Mount Baker, a stratovolcano in Washington state's North Cascades. The project commenced commercial operation in October 1990, and is owned by a Covanta Energy–Atlantic Power joint venture. It supplies Puget Sound Energy via a Power Supply Agreement (PSA) contract. Its single turbine is a Pelton wheel supplied by Sulzer Escher Wyss.
Located in the Mount Baker National Forest, it is one of six Federal Energy Regulatory Commission (FERC)-licensed small hydro installations on Federal Government land in Washington state.
"Koma Kulshan" is the name of Mount Baker in the Lummi dialect.
