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:

	Miles
Distribution Lines	Overhead	Underground
69 kV	7	1
13.8 kV and under	950	947
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 net generating capability in service at December 31, 2004, was as follows:

Plants	Location	Fuel	Net Capability (MW)	No. of Units
Steam plants:
Columbia	Portage, WI	Low-sulfur coal	225 (1,2)	2

² MGE's 22% share of two, 512-MW units located near Portage, Wisconsin. The other owners are Alliant Energy Corp., which operates Columbia, and Wisconsin Public Service Corporation.

MGE's gas facilities include 2,277 miles of distribution mains (all located in Wisconsin).

MGE supplied natural gas service to nearly 133,000 customers in the cities of Elroy, Madison, Middleton, Monona, Fitchburg, Lodi, Prairie du Chien, Verona, and Viroqua; 24 villages; and all or parts of 45 townships, all in Wisconsin.

MGE has physical interconnections with ANR Pipeline Co. (ANR) and Northern Natural Gas Co. (NNG). MGE's primary service territory, which includes Madison and the surrounding area, receives deliveries at one NNG and four ANR gate stations. Interconnections with two major pipelines provide competition in interstate pipeline service and a more reliable and economical gas supply mix, which includes gas from Canada and the United States mid-continent and Gulf/offshore regions.
