Corridor Business Journal: Alliant Energy says it's reached a partial settlement with other stakeholders on a major electric rate case before the Iowa Utilities Board that will increase electrical rates for its Iowa customers less than originally sought. The partial settlement, if approved by the board, "will result in a modest base rate increase from interim rates in 2020 - which would be smaller than the final rates originally requested," the company said in a release. It did not indicate how much rates will go up for different customer classes, saying they will be determined in a subsequent ratemaking portion of the case.
