The wind turbine in Alan and Kris Miller's backyard sent reverberations across Minnesota on Thursday.
The couple, who live outside Stewartville, Minn., installed the 140-foot-high turbine in 2011 to power much of their small hobby farm. Then their electric utility tacked on a $5-per-month charge for having it, and Alan Miller wrote a letter complaining to state regulators.
That blew open a controversy leading to the Minnesota Public Utilities Commission's decision Thursday to order all of the state's more than 100 electric utilities to report whether they charge similar fees. It's the first step in what could become a broader investigation of whether the fees are fair.
"I'm happy, but not elated," said Alan Miller, who will get back all of his money, about $90 plus interest, after People's Energy Cooperative agreed to drop the fee and offer refunds to him and 31 other customers hit with them after they installed solar panels or wind turbines.
Miller, a retired metal finisher, isn't elated because the battle over such fees isn't over. Under a new law that cooperative and municipal utilities pushed in the 2015 state Legislature, the fees likely will come back — if power companies can justify them to regulators.
Now, the worry by Miller and other renewable energy advocates is that anyone considering solar or wind power won't invest until it's clear what, if any, extra fees they'll have to pay their utility.
"They have no idea what the fee is going to be," said David Shaffer, general counsel for the Minnesota Solar Energy Industries Association, a trade group. "Maybe it is going to be $5 and maybe it is going to be $85 — until they know, they can't make an informed purchasing decision so they choose not to buy."
The fears of fees as high as $85 stem from an Iowa cooperative utility's proposal to significantly increase charges to customers who install new solar or wind generators. Of the five Minnesota utilities known to have such fees, Oronoco-based People's was the highest at $5 per month.
