Alliant Energy announced October 29 that its projected capital spending for 2027 through 2030 had increased 19% to $15.9 billion.
The utility company said its Interstate Power and Light and Wisconsin Power and Light subsidiaries have 3.4 gigawatts of contracted data-center demand. Management expects peak electricity demand to increase approximately 60% by 2031. That estimate is a forecast rather than an observed increase.
Alliant reported third-quarter GAAP earnings of $1.52 a share, up from $1.09 a year earlier. For the first nine months, GAAP earnings were $3.04 a share, compared with $2.59.
The company narrowed its 2026 ongoing earnings forecast to $3.41–$3.46 a share, the upper half of its original range. Ongoing earnings are a company-defined measure separate from GAAP results.
It issued 2027 earnings guidance of $3.63–$3.73 a share and an annual common-stock dividend target of $2.25. A dividend target describes management's expectation, rather than a completed payment.
