DES MOINES, IOWA (March 28, 2019) — The Iowa Utilities Board (IUB) on Monday issued an order approving Alliant Energy's five-year energy efficiency plan with few modifications. The approval of Alliant's plan is the end result of Senate File 2311, legislation passed by the Iowa Legislature in 2018 that severely restricted what the IUB could require utilities to spend on programs to help customers reduce energy usage.
