Alliant Energy will soon propose a rate increase averaging 4-6 percent for its natural gas customers in Iowa.
The company’s Interstate Power and Light utility plans to file the rate increase request on May 25 with the Iowa Utilities Board. The increase would apply only to the service costs on the customer’s natural gas bill, which average 30-40 percent of the total bill, company spokesman Justin Foss said.
IPandL is not the dominant natural gas supplier in the Corridor. Its local markets include Mount Vernon, Lisbon, Palo and Vinton.
Foss said natural gas bills have dropped about 19 percent since 2005 at IPandL, due mainly to lower wholesale natural gas prices.
IPandL’s last natural gas rate increase was seven years ago.
Specific factors driving the company to seek a rate increase will be disclosed at the time of the filing, Foss said. The increase is expected to vary between different customer classes.
