Item 8.01. Other Events.

On September 30, 2005, MGE Power Elm Road, LLC, a subsidiary of MGE Energy, Inc. (Nasdaq: MGEE), exercised its options to acquire ownership interests in the coal-fired, baseload generation facilities proposed in We Energies' Power the Future plan. Pursuant to the ownership agreements governing the options, exercising these options will provide MGE Power Elm Road with an undivided 8.33% ownership interest in each of two 615-megawatt generation units being constructed in Oak Creek, Wisconsin. MGE Power Elm Road's ownership interest translates to approximately 50 megawatts per unit. MGE Power Elm Road's share of capital costs for its ownership interest in both units is currently estimated to be approximately $190 million, which would be incurred between 2005 and 2010. Closing on these options is scheduled for November 4, 2005. On that date, MGE Power Elm Road will be required to make an initial payment for project costs of approximately $22 million to We Energies.
