Regulators Decline Rehearing in Solar Net Metering Dispute
Minnesota's utility commission refused to reconsider a farmer's petition against a rural electric cooperative over solar power payments.
Updated on Nov. 2, 2026 in Utilities
The Minnesota Public Utilities Commission unanimously voted October 28 not to reconsider Larry Rauenhorst's petition against Renville Sibley Cooperative Power Association. The commission said the matter is a rate dispute outside its authority and urged mediation, which failed in July, and Rauenhorst has filed a civil lawsuit.
Why it matters
The case tests whether a farm-field solar array qualifies for the average retail rate under Minnesota's net metering law. Its outcome could shape how cooperatives and small solar producers across Minnesota handle compensation for excess power.
The system is rated at 37 kilowatts and includes 80 solar panels mounted on 10 towers standing 12 feet high. The commission has not ruled on whether it has authority over the compensation question, and the civil case has no announced schedule.
The players
Larry Rauenhorst
A Renville County farmer who installed the solar system and is pursuing the rate dispute and a civil lawsuit against the cooperative.
Renville Sibley Cooperative Power Association
A rural electric cooperative serving Renville County that argues the Minnesota Public Utilities Commission lacks authority over the dispute.
Minnesota Public Utilities Commission
The state regulatory body that declined to reconsider the petition, stating the matter is a rate dispute with a cooperative outside its authority.
The details
Rauenhorst and his brother installed the panels on farmland south of Olivia, elevating them so crops can grow underneath, and are working with the University of Minnesota on the project. The brothers say the cooperative must pay the average retail rate for excess power under net metering law, while the cooperative argues the farm-field system does not serve a house, farm, or business and falls outside the law's intent.
Timeline
May: The commission denied Rauenhorst's original petition.
July: Mediation between Rauenhorst and the cooperative was unsuccessful.
October 28: The commission voted not to reconsider the petition.
Industry Context
The case extends the debate under Minnesota's net metering law over whether excess solar output from non-residential installations must be credited at the average retail rate. Its resolution could define how the state's rural cooperatives treat similar farm-based arrays.
Minnesota solar owners on farms that export power to a cooperative could face uncertainty over whether they receive retail-rate credits for excess electricity. Until the civil lawsuit resolves the question, compensation terms for similar systems remain unsettled.
The takeaway
Farm-based solar projects in Minnesota should confirm how their cooperative will compensate excess power before committing to an installation.
