CEDAR RAPIDS, Iowa, June 17 /PRNewswire-FirstCall/ -- Interstate Power and Light Company (IPL), a subsidiary of Alliant Energy Corporation (NYSE: LNT), today received an oral decision from the Minnesota Public Utilities Commission (MPUC) regarding its request to implement an interim increase in its Minnesota electric retail rates.

In its oral decision, the MPUC authorized an increase in electric revenues of approximately $14.1 million or 20.4 percent. Interim rates are expected to become effective July 6, 2010. The impact of the proposed change in electric rates will vary depending on customer class. The MPUC established a return on common equity of 10.39 percent during the interim period.

IPL had requested an interim increase in electric revenues of approximately $14.5 million or 21 percent.

"The MPUC's decision today enables our company to begin recovering the costs of the $1 billion of investments made for the benefit of our customers over the past five years to provide safe, reliable and clean energy service," says Tom Aller, President - IPL. "Since our last request to change base rates in 2005, we have been making investments that enhance the safety and reliability of our electric system for our customers while reducing our impact on the environment as we lessen our power plant emissions and increase our use of renewable energy."

Interim rates are expected to remain in place until the third quarter 2011 when the MPUC's final decision on the company's electric rate request becomes effective. If the final electric revenues approved by the MPUC are lower than the interim revenue levels, IPL will issue refunds equal to the difference between the interim and final rate levels, plus interest.

IPL anticipates that additional details regarding today's decision will be included in the MPUC's written order, expected to be issued prior to July 6, 2010.

"We recognize that while these investments are made for the benefit of our customers, there are also cost implications and we are committed to managing our costs while working with customers to also manage their energy costs through a variety of energy efficiency actions and programs," adds Aller.

On May 7, 2010, IPL filed a request with the MPUC to increase annual base revenues by approximately $15 million, or 22 percent. The MPUC had sixty days after IPL's filing to issue a decision that suspended the company's proposed final rates and allowed implementation of interim rates while the MPUC considers the company's request.
