Madison, Wis., May 2, 2003--MGE Energy, Inc. (Nasdaq: MGEE) reports first-quarter net income of $9.4 million or 53 cents per share. MGE Energy's net income for the twelve months ended March 31, 2003, was $27.5 million or $1.58 per share. MGE Energy's operations are based primarily on its utility subsidiary Madison Gas and Electric Co. (MGE).

Electric revenues were up $5.3 million in the first quarter as MGE's retail sales grew 2.4%, and average rates were 3.9% higher. MGE also sold 25 megawatts of electric capacity for which the contract extends through August 2003.

MGE's electric margin (revenues less fuel costs) decreased $2.7 million mainly because fuel costs for electric generation were up $2.1 million. Substantially higher natural gas prices drove up fuel costs. Outages at the coal-fired Columbia Energy Center (Columbia) in the first quarter required MGE to rely more on its gas-fired plants, which cost more to operate. Purchased power costs also rose $5.9 million, reflecting higher gas prices. MGE's generation mix includes more electricity bought from gas-fired plants since two new purchased power contracts took effect in May 2002.

MGE's gas revenues were up $24.9 million as colder weather helped increase retail gas deliveries by 20%, and the average price of natural gas was 43% higher in the first quarter. The increase in gas delivered resulted in a $3.8 million increase in MGE's gas margin (revenues less purchased gas costs).

Operations expenses increased $4.5 million in the first quarter mainly due to higher costs for transmission wheeling ($1.7 million), employee pensions and benefits ($1.7 million), electric and gas distribution expenses ($0.4 million) and other general expenses ($0.7 million). Electric maintenance costs were up $0.8 million as more work was required at Columbia and MGE's Blount Station. Depreciation expenses were down $1.6 million for the quarter since MGE had no decommissioning depreciation for the Kewaunee Nuclear Power Plant (Kewaunee) during the quarter. On Jan. 3, 2003, MGE transferred the balance of the nonqualified decommission fund to Wisconsin Public Service Corp. (WPSC) in accordance with the Kewaunee sale agreement. MGE sold its interest in Kewaunee to WPSC in September 2001.

MGE Energy is a public utility holding company. Its principal subsidiary, Madison Gas and Electric Co. (MGE), generates and distributes electricity to nearly 130,000 customers in Dane County, Wisconsin, and purchases and distributes natural gas to more than 126,000 customers in seven south-central and western Wisconsin counties.
