Alliant Energy Reaffirms 2026 Guidance as Data Center Pipeline Drives 60% Demand Surge
The Midwest utility is tracking toward the upper half of its earnings range despite milder weather, as it advances agreements with Google, Meta, and QTS totaling gigawatts of new load.
Strong Quarter Despite Weather Headwinds
Alliant Energy Corporation reported second-quarter 2026 GAAP earnings of $0.65 per share and reaffirmed its full-year earnings guidance, with management indicating the company is "currently trending in the upper half of our 2026 earnings guidance range" (earnings call, 2026-07-31). This performance came despite milder-than-normal temperatures that reduced second quarter electric and gas margins by approximately $0.03 per share.
The Madison, Wisconsin-based utility, which serves customers across Iowa and Wisconsin, delivered year-over-year earnings growth driven by higher revenue requirements from capital investments and increased equity earnings from corporate venture fund investments. Excluding temperature impacts, second quarter electric sales increased approximately 3% year-over-year, reflecting strength in Wisconsin's commercial and industrial sectors and the initial ramp of data center loads in Iowa.
Data Center Pipeline Reshapes Growth Trajectory
CEO Lisa Barton announced that the company expects "a 60% increase in our demand by 2031" (earnings call, 2026-07-31), driven by five executed electric service agreements with large load customers. Three projects are already under active construction with commission-approved contracts.
In Cedar Rapids, Iowa, Google has energized transmission service and is "anticipating ramping in accordance with the contracted load schedule" (earnings call, 2026-07-31). Also in Cedar Rapids, QTS is constructing a seven-building data center campus with initial energization of 300 megawatts expected later this year. In Beaver Dam, Wisconsin, Meta has entered vertical construction on its data center facility.
Alliant also announced progress on future opportunities, including a QTS project in Clinton, Iowa, for which the company plans to file an Individual Customer Rate application for 900 megawatts later this year. The company disclosed a recently signed 370-megawatt data center agreement in Iowa and noted that its customer pipeline "currently represents between 2 and 4 gigawatts of potential future load" (earnings call, 2026-07-31).
Infrastructure Investment and Financing Strategy
CFO Robert Durian outlined significant financing progress, noting the company has raised approximately $1.8 billion of its $2.4 billion common equity needs through 2029 via forward equity agreements. This leaves approximately $500 million of remaining equity to be raised through 2029, providing "meaningful flexibility to support the efficient implementation of our strategy" (earnings call, 2026-07-31).
On the generation front, Alliant filed certificates for the 720-megawatt Morgan Valley and 1.2-gigawatt River Hawk simple cycle natural gas projects, along with approximately 125 megawatts of energy storage. The company recently started construction on the 720-megawatt Bobcat Energy Center in Marshalltown, Iowa, and the 95-megawatt Rice project in Burlington, Iowa.
Alliant was also awarded approximately $200 million in Department of Energy grants for its Columbia Energy Center and energy storage projects.
Long-Term Outlook Intact
Management maintained its longer-term earnings outlook, expecting "compound annual earnings growth across 2027 through 2029 to be 7% plus" (earnings call, 2026-07-31). The company plans to update its capital expenditure and financing plans on the third quarter earnings call.
Barton emphasized that the company's approach ensures large load customers "pay their own way while creating opportunities to further reduce costs for existing customers" (earnings call, 2026-07-31), addressing concerns about cost allocation between new and existing ratepayers.
