Rates mentioned in web material subject to change On October 1, 2007, Otter Tail Power Company submitted a proposal to the Minnesota Public Utilities Commission (MPUC) to increase base rates for electric service in Minnesota for the first time since 1986. On November 27, 2007, the MPUC approved our request to increase rates by approximately 5.4 percent—over what customers paid in 2006, including the cost-of-energy adjustment—on an interim, or temporary, basis beginning November 30, 2007. The proposed interim rate increase will remain in effect until the MPUC decides the case in August 2008. Information reported on this web site does not reflect interim or final rate increases. We will update all rate information after the MPUC makes its final decision. |
