2. Provide a brief description of the properties of claimant and each of its subsidiary public utility companies used for the generation, transmission, and distribution of electric energy for sale, or for the production, transmission, and distribution of natural or manufactured gas, indicating the location of principal generating plants, transmission lines, producing fields, gas manufacturing plants, and electric and gas distribution facilities, including all such properties which are outside the state in which claimant and its subsidiaries are organized and all transmission or pipelines which deliver or receive electric energy or gas at the borders of such state.

MGE Energy is a holding company and is not expected to directly own any facilities for generating or distributing electric energy or for producing or distributing natural or manufactured gas.

MGE's major electric distribution lines and substations in service at December 31, 2004 (all located in Wisconsin), are as follows:

Distribution Substations Installed Capacity (kVA)
69-13.8 kV 23 809,000
13.8-4 kV 32 308,000

On January 1, 2001, MGE transferred its electric transmission assets to ATC. In exchange for its transmission plant and related deferred taxes and deferred investment tax credits, MGE received approximately a 5% ownership interest in ATC. MGE receives a return on its investment in ATC that is approximately equal to the return it would have earned by retaining its transmission facilities. A small portion of the 69-kilovolt (kV) lines and substations has been classified as distribution assets.

MGE's primary service territory, which includes Madison and the surrounding area, receives deliveries at one NNG and four ANR gate stations.
