Koma Kulshan Hydroelectric Project
The Koma Kulshan Hydroelectric Facility is a 13.3 MW run-of-river power plant located on the slopes of Mount Baker in the North Cascades region of Washington state. Since commencing operations in October 1990, this plant has been jointly owned by Covanta Energy and Atlantic Power, with electricity supplied to Puget Sound Energy under a Power Supply Agreement. The facility utilizes a single Pelton wheel turbine manufactured by Sulzer Escher Wyss.
Positioned within the boundaries of Mount Baker National Forest, Koma Kulshan is among six small hydroelectric projects licensed by FERC on federal lands throughout Washington. The name "Koma Kulshan" originates from the Lummi language, referring to Mount Baker.
Dams
Water intakes are situated at diversion dams on the Rocky Creek and Sulphur Creek tributaries feeding into Lake Shannon. A penstock measuring in diameter and in length transports water from a bifurcation point at elevation (a.s.l.) to the powerhouse. After passing through the turbine, water is released into Sandy Creek, which flows a short distance before entering Baker Lake. The facility can divert up to of water flow to generate power.
The Rocky Creek diversion dam stands high and stretches long at an elevation of . Similarly, the Sulphur Creek diversion dam measures in height and in length, located at an elevation of .
The diversion of water from these creeks has altered the natural flow and appearance of Upper and Middle Sulphur Creek Falls.
Peak generation
Energy production reaches its highest levels between May and July, aligning with seasonal snowmelt, with a secondary peak occurring in November during the wetter months.
