Item 1.01. Entry into a Material Definitive Agreement.


On September 29, 2006, Madison Gas and Electric Company (MGE) formalized their plans to acquire 29.7 megawatts or 18 turbines in a wind-powered electric generating facility that will be constructed in Worth County, Iowa. Pursuant to these plans, MGE entered into contractual arrangements with Vestas Wind Systems A/S and Midwest Renewable Energy Corporation for the required wind turbines, substation, and land. These contractual arrangements account for approximately $46 million or over 80% of the estimated total project costs. MGE plans to finance these project costs through short- and long-term debt, operating cash flows, and capital contributions received from its parent, MGE Energy, Inc. (MGE Energy). Construction on this facility is expected to commence immediately and is expected to be completed by no later than December 31, 2007.
