Alliant Energy Corporation earnings call
Buzzberg read
New 370 MW data center agreement in Iowa, ramping by 2030
Alliant Energy's Q1 2026 call was overwhelmingly positive, anchored by strong execution on its data center growth strategy to support 2-4GW of new load opportunities. Management reaffirmed its 2026 guidance and provided a bullish multi-year outlook with a 7%+ EPS CAGR projected through 2029, underpinned by new capacity-only service contracts and a flexible resource plan featuring simple-cycle gas turbines and batteries. Reaffirmed FY2026 guidance with Q1 ongoing EPS of $0.82, slightly below the 25% mark due to mild weather, offset by tax audit benefits.

Management read
Confident
Management expressed confidence in executing data center growth and reaffirmed guidance, emphasizing strong progress and a robust pipeline of opportunities.
Investment and capacity
Management highlighted a 1.1 GW simple-cycle gas plant agreement to support a new 370 MW data center ESA, with plans for a refreshed Iowa resource plan and incremental capex funded by a balanced mix of debt and equity. They also plan to file for a 720 MW gas CT in Iowa and several renewable projects in Wisconsin, with a capital plan expected to grow rate base by ~12% annually.

Alliant signed an agreement for an up-to-1.1GW simple cycle gas turbine, far exceeding the initial 370MW data center load, suggesting an aggressive build for future load or MISO accreditation requirements. — Indicates strong demand for grid-scale turbines in the US Midwest, a positive signal for turbine manufacturers.
Evidence
“we've entered into a contract for up to the 1.1 that allows us to be very flexible”

Alliant signed an agreement for an up-to-1.1GW simple cycle gas turbine, far exceeding the initial 370MW data center load, suggesting an aggressive build for future load or MISO accreditation requirements.
Alliant's significant capacity-only contracts for data centers are enabling load growth without triggering base rate reviews in Iowa through at least the end of the decade, a strong indicator of low-cost capital expenditure accretion and regulatory stability.
Evidence
“we can keep base electric rates stable through at least the end of the decade”
Iowa's wind resource (15GW of wind vs 6GW of load) is a unique strategic advantage for Alliant, allowing data centers to be served with capacity resources (peakers/batteries) rather than expensive baseload fuel, lowering overall cost and speeding time to market.
Evidence
“there's about six gigawatts worth of load today between MidAmerican and Alliant and about 15 gigawatts of wind”
