Alliant targets 1 GW of new data-center contracts in six months as power demand surges
Alliant Energy expects to sign contracts for about 1 gigawatt of additional data-center electricity demand within six months, adding to 3.4 gigawatts already contracted with Google, Meta and QTS Data Centers. The Madison-based utility expects the new demand to ramp up between 2029 and 2031 as AI adoption drives power consumption higher.
Alliant Energy expects to secure contracts covering roughly 1 gigawatt of additional data-center demand within six months, Chief Financial Officer Robert Durian said during an earnings call. The prospective load would add to 3.4 gigawatts already contracted with Google, Meta and QTS Data Centers, with the new demand expected to ramp up from 2029 through 2031.
The Madison, Wisconsin-based utility raised its 2027-2030 capital-spending forecast by 19% to $15.9 billion and expects peak demand across its system to rise more than 60% by 2031. Meta is also expected to begin taking transmission service in Wisconsin in early 2027. Alliant serves about 1 million electric customers in Iowa and Wisconsin, where expanding data-center capacity and AI adoption are contributing to rising electricity demand.
