Despite its relatively modest size, Alliant has emerged as one of the most aggressive clean energy developers among US regulated utilities. Under Larsen's leadership, Alliant has invested billions in wind farms and solar installations, dramatically reducing its coal generation fleet and targeting net-zero carbon emissions. The company's clean energy transition has been supported by favorable regulatory relationships in both Iowa and Wisconsin, where regulators have approved large-scale wind and solar investments with timely cost recovery. This regulatory constructiveness is a key competitive advantage. His strategic decisions revolve around the pace of renewable energy capital deployment, grid modernization investment, rate case strategy in both regulatory jurisdictions, customer affordability considerations (balancing clean energy investment with rate impacts), and potential data center and large load growth in the Midwest. Alliant's stock is valued as a premium regulated utility offering above-average rate base growth from its clean energy transition program.
