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.
Intakes are located at diversion dams on the Rocky Creek and Sulphur Creek tributaries of Lake Shannon. A 42inch45inch diameter, 19250feet long penstock carries water from a bifurcation (48.6914°N -121.7919°W, a.s.l.) to the powerhouse. Water is discharged from the powerhouse through a short run on Sandy Creek to Baker Lake. Up to is diverted to the powerhouse.
(48.6849°N -121.8065°W) is high, long at a.s.l.
(48.6928°N -121.7928°W) is high, long at a.s.l.
Diversion of the creek affected the appearance of Upper and Middle Sulphur Creek Falls.
Power generation peaks in May through July coinciding with snowmelt, and has a smaller peak in November coinciding with the wet season.
