Alliant Energy supplies electricity and gas to Iowa and Wisconsin — a quiet region and predictable construction.
Profit is set by the rate base and the allowed return, so the capital plan replaces a revenue forecast here: replacing coal with wind and solar, energy storage, hardening networks. Iowa has one of the country's best wind resources, which makes that replacement cheaper than in most states.
Demand is supported by industrial connections and by data centres coming to the region for cheap power and a cool climate. Relations with the two states' regulators have historically been calm, which for a utility matters no less than asset quality. Risks: commission decisions, borrowing costs and weather. The dividend is raised annually.
