Alliant Energy combines regulated utility defensiveness with unusually visible data-center-driven growth, but its premium valuation depends on flawless capex execution, supportive regulators, and disciplined financing.
Overview
Alliant Energy is a regulated Midwest electric and gas utility serving roughly 1.0 million electric and 435,000 gas customers through Iowa and Wisconsin subsidiaries. Over 95% of ongoing earnings come from regulated utility operations, supported by monopoly service territories and an ATC transmission stake. Electricity drives more than 85% of revenue. The investment story is defensive but increasingly growth-oriented, as clean energy assets, grid reliability, business-friendly policies, and tailored data-center rate structures position Alliant to capture large energy-intensive industrial demand.
