Investment in ATC Disclosure [Abstract]

3. Investment in ATC - MGE Energy and MGE.

ATC owns and operates electric transmission facilities primarily in Wisconsin. MGE received an interest in ATC when it, like other Wisconsin electric utilities, contributed its electric transmission facilities to ATC. That interest is presently held by MGE Transco, which is jointly owned by MGE Energy and MGE.

MGE Transco has accounted for its investment in ATC under the equity method of accounting. For the three months ended March 31, 2013 and 2012, MGE Transco recorded equity earnings from the investment in ATC of $2.4 million and $2.2 million, respectively. Dividend income received from ATC was $1.8 million and $1.7 million for the three months ended March 31, 2013 and 2012, respectively. In addition, during the three months ended March 31, 2013 and 2012, MGE Transco made $0.2 million and $0.4 million in capital contributions to ATC, respectively.

At March 31, 2013, MGE is the majority owner, and MGE Energy, the holding company, is the minority owner of MGE Transco. MGE Energy's proportionate share of the equity and net income of MGE Transco is classified within the MGE financial statements as noncontrolling interest.
