Minnesota utility regulators on Thursday approved Xcel Energy's plan that will result in closing three biomass electricity generators.
The move will save ratepayers money but will also lead to some economic distress for the timber and turkey farming industries.
Xcel plans to buy and close a plant in the western Minnesota town of Benson, which burns turkey manure to produce electricity. The Minneapolis-based utility will also buy out its contract to purchase power from two wood-burning plants on the Iron Range.
The three plants produce only a sliver of Xcel's electricity.
Xcel made the case successfully to the Legislature earlier this year that the biomass plants are the most expensive electricity producers on its system, costing up to 10 times more than wind power. Lawmakers responded by allowing Xcel to effectively end its biomass power contracts about 10 years before they would expire, pending approval by the Minnesota Public Utilities Commission (PUC).
Xcel says the Benson buyout will lead to long-term cost savings of $345 million; the Iron Range buyout, $87 million.
"These are very large savings for ratepayers that need to be implemented as soon as possible," said Matt Schuerger, a member of the PUC, which voted 5-0 in favor of the biomass deals.
The buyouts have been met with major opposition from loggers and timber companies in the north and Minnesota's turkey industry.
