The Iowa Utilities Board approved a request by Alliant Energy Corp. to raise its natural gas rates, but even with the approved 6% increase, local customers will see minimal changes in their gas bill.
In a Dec. 14 release, the Madison, Wis.-based energy utility said residential customers in Iowa will only see a 1% increase in final rates in early 2019 over current rates, or about $1.50 per month for usual bills, bringing the monthly bill to about $57. The amount represents a decrease from the usual monthly bill of $66 in 2012, which Alliant Energy attributed to lower costs for natural gas, decreased usage from customers and savings from lower corporate taxes.
Customers are already seeing the rest of the 6% increase when interim rates became effective in May, according to the utility.
Alliant Energy has kept its natural gas rates steady since 2012. Alliant Energy will continue to maintain more than 5,000 miles of natural gas pipelines in Iowa through replacements of aging infrastructure, conducting safety inspections and service expansions, said Terry Kouba, vice president of Alliant Energy's Iowa operations.
Alliant Energy provides services to 960,000 electric and 410,000 natural gas customers, with a focus in the Midwest.
