MGE Energy Reports Third-Quarter Earnings

Madison, Wis., Nov. 12, 2007—MGE Energy, Inc. (Nasdaq: MGEE) today reported earnings for the three months ended Sept. 30, 2007, of $15.5 million or 71 cents per share, compared to $12.7 million or 62 cents per share during the same period in the prior year.

One factor contributing to the earnings for the third quarter was sales growth at the electric segment. During the three months ended Sept. 30, 2007, electric deliveries increased 3.1% from those in the same period in the prior year. The increase in electric deliveries primarily represents increased residential and commercial usage. Additionally, during the three months ended Sept. 30, 3007, MGE Energy received a $0.6 million payment from the Midwest Independent System Operator (MISO) that reduced purchased power expense.

Also contributing to higher earnings is an increase in revenues from the recovery of carrying costs related to MGE Energy's construction activities. As a result of the construction activities at Elm Road and the Top of Iowa III wind project, MGE Energy recognized $1.1 million in additional revenue for the three months ended Sept. 30, 2007.

Its principal subsidiary, Madison Gas and Electric (MGE), generates and distributes electricity to nearly 135,000 customers in Dane County, Wis., and purchases and distributes natural gas to more than 138,000 customers in seven south-central and western Wisconsin counties.
