Regulators approve 15 percent increase to Otter Tail Power fixed fee

Last week, the Minnesota Public Utilities Commission approved an increase to Otter Tail Power’s monthly fixed fee from $8.50 to $9.75. The case wraps up roughly a year after Otter Tail Power submitted its initial proposal. In February 2016, Minnesota-based investor-owned utility Otter Tail Power filed its first rate case since 2010, asking for an overall rate increase of 9.8 percent that would have increased revenue by more than $19 million. Fresh Energy intervened in the case to provide expert testimony challenging the requested customer charge increase, and recommending alternative rate designs.
