MGE Energy Reports Third-Quarter Earnings

Madison, Wis., Nov. 7, 2013—MGE Energy, Inc. (Nasdaq: MGEE) today reported earnings for the three months ended Sept. 30, 2013, of $24.4 million, or $1.05 per share, compared to $23.6 million, or $1.02 per share, for the same period in the prior year.

For the quarter ending Sept. 30, 2013, the company benefitted from higher gas sales volumes of 4.3% reflecting higher customer demand during the third quarter of 2013. Also contributing to earnings during the quarter was the benefit of the carrying costs on the construction of the environmental controls at the Columbia Energy Center and savings from the continuation of MGE's ongoing effort to manage costs.

The company also experienced a 2.7% decrease in electric retail sales reflecting lower customer demand. The decline in customer demand was driven by a return to more normal weather in 2013 compared to unusually warm weather in 2012. The July 2013 average temperature of 71.9 degrees was 9.8% lower than the average temperature of 79.7 degrees in July 2012. The normal average temperature in July is 72.4 degrees.
