POWER Engineers performed a due diligence of the Victoria Hydroelectric Station on the West Branch of the Ontonagon River approximately 18 miles upstream of its mouth on Lake Superior. The due diligence review was part of Independent Engineering assignment to support the acquisition of the facility and the local utility by a U.K.-based infrastructure investment fund. The due diligence review included a conditions assessment, an environmental compliance and FERC licensing review, and OpEx and CapEx assessments.
The facility was built in 1930 outside Rockland, Michigan. The powerhouse contains two Francis-type generating units capable of producing 12.2 MW of power and operating at a head range of approximately 214 feet. The penstock delivers water from the dam’s intake structure to the powerhouse about 6,300 feet downstream. The above ground pipeline consists of a steel penstock supported on free draining ballast on the ground. The 9-foot 5-inch diameter steel penstock was replaced in 2002.
