Iowa Natural Gas Rates

Natural gas rates for Iowa customers of Alliant Energy adjusted in January 2013 as part of the base rate case filed in May 2012.

The Iowa Utilities Board (IUB) approved the settlement Alliant Energy reached between the Iowa Office of Consumer Advocate (OCA) and the Iowa Consumers Coalition (ICC) in regards to its base rate case in November 2012.

The cost of gas makes up, on average, 60 to 70 percent of the average residential natural gas bill. This cost of gas is a dollar-for-dollar pass-through for customers, and is unaffected in this rate case outcome.

The cost for the gas itself is reflected in the Purchased Gas Adjustment (PGA). This adjustment is updated monthly in a tariff filing to the IUB. You can view a brief summary of this here.
