Item 8.01. Other Events


On November 4, 2005, MGE Power Elm Road, acquired a 8.33% ownership interest in each of two 615-megawatt generating units being constructed in Oak Creek, Wisconsin. MGE Power Elm Road estimates it share of capital costs for its 8.33% ownership interest in both units to be approximately $171 million. MGE Power Elm Road is owned indirectly by MGE Energy through its wholly owned subsidiary MGE Power. MGE Power Elm Road is not a subsidiary of MGE; however it is consolidated in the financial statements of MGE due to the application of FIN 46R


In March 2005, the Wisconsin Department of Natural Resources (the "WDNR") determined that the proposed cooling water intake structure and water discharge system for our Oak Creek expansion met all necessary regulatory requirements and reissued a Wisconsin Pollutant Discharge Elimination System ("WPDES") permit for Oak Creek. The WDNR granted opponents a contested hearing, and an administrative law judge upheld the issuance of the permit in a decision issued in July 2006. In August 2006, opponents filed for judicial review of the administrative law judge's decision. Briefing was completed in December 2006. On January 26, 2007, the opponents filed a motion with the Dane County Circuit Court for supplemental briefing. In a telephone conference on February 2, 2007, the Court said that additional briefing is not necessary, but that it might request oral argument before issuing its decision regarding review of the permit.


The opponent's motion for supplemental briefing cited a Second Circuit decision issued on January 25, 2007, concerning the United States Environmental Protection Agency's Phase II Rule under Section 316 (b) of the Clean Water Act. Riverkeeper, Inc. v. EPA, Nos. 04-6692-ag(L) et al. (2d Cir. 2007).


The WPDES permit relating to our interest in the Oak Creek expansion is a state permit that has been issued by the WDNR, with the concurrence of the EPA, not a federal permit. We do not believe the decision invalidates the WPDES permit for Oak Creek and continue to believe the proposed cooling water intake structure is the best technology available for protection of the environment at Oak Creek.


In the event the WPDES permit were to be invalidated, we may incur significant additional costs relating to the Oak Creek cooling water system. Under the terms of the Public Service Commission of Wisconsin ("PSCW") order approving the Oak Creek expansion, if final construction costs are within 5% of the target cost, we would be entitled to recover the additional costs if the PSCW deems such costs to be prudent. To recover any costs above the 5% cap from customers would require a finding of extraordinary circumstances, such a force majeure conditions. We believe any such additional costs that might result from an invalidation of the WPDES permit should be recoverable, subject to review and approval by the PSCW.


The ultimate outcome of these matters cannot be determined at this time.


For additional information regarding the WPDES permit, please refer to "Quantitative and Qualitative Disclosures About Market Risk" in Item 7A of the Form 10-K for the year ended December 31, 2005.
