The Koma Kulshan Project is a 13.3 MW run-of-the-river hydroelectric generation facility located on the slopes of Mt. Baker, north of Seattle, Washington. It commenced commercial operation in October 1990. The project sells its electrical output to Puget Sound Energy, Inc. under a long-term power purchase agreement expiring in March 2037. The Koma Kulshan Project holds two hydroelectric licenses from the FERC that expire at the same time as the PPA.
Prior to June 2018, Atlantic Power had owned 49.75% of the project. In June 2018, Atlantic Power acquired an additional 0.25% interest in the project from Mt. Baker Corporation for $1.1 million. In July 2018, Atlantic Power acquired the remaining 50.00% interest in the project from Covanta for $11.8 million and bought out the operation and maintenance contract held by Covanta for another $0.3 million. Following closing, Atlantic Power owns 100% of Koma Kulshan and is the operator of the facility.
