In plain English
Alliant Energy is a Midwest regulated electric-and-gas utility holding company. It delivers power and natural gas to roughly a million electric and 430,000 gas customers across Iowa (through its IPL utility) and Wisconsin (through WPL) at state-approved rates — and is now riding one of the biggest load booms in its history as Google, Meta and QTS build giant AI data centres in its territory, driving a $13.4B four-year build-out as it exits coal and pivots to wind, solar, storage and new gas.
