Great River Energy, the state's second-largest electric supplier whose rising wholesale rates have come under fire, is losing a large customer that decided it could purchase cleaner, cheaper electricity elsewhere.
Elk River Municipal Utilities, which for decades has relied on Great River Energy to generate electricity for its customers, said it has signed a deal to obtain future power from the Minnesota Municipal Power Agency (MMPA) owned by 11 municipal power companies.
Troy Adams, general manager of the Elk River utility, said Great River's rising wholesale rates — up 58 percent since 2006 — are the main reason for making the switch, which takes effect in 2018.
"The No. 1 driving reason is we want to remain competitive, and wholesale power rates are 75 percent of our costs," Adams said in an interview.
It is the latest sign of discontent among customers of the Maple Grove-based wholesale power cooperative, which is owned by 28 local co-ops that serve 645,000 homes and businesses across the state. Two ethanol producers recently complained to state regulators that Great River has invested in questionable projects, including a new coal-fired power plant, that drove up rates.
Great River Energy has denied that its wholesale rates are out of line with other utilities in the region, and last week, its CEO, David Saggau, said at the co-op's annual meeting that he expects no rate hike in 2014. Unlike investor-owned utilities, whose rates are set by state regulators, most co-ops can legally set rates on their own.
Elk River Municipal Utilities, which has nearly 10,000 customers, purchases about 2 percent of the power Great River generates at times of peak demand in the summer.
Adams said the Elk River utility was concerned about Great River's heavy reliance on coal to generate power. About 45 percent of Great River's generating capacity is from coal-fired power plants, and they are heavily used, producing 70 percent of the co-op's electricity last year, according to utility data.
