Alliant Energy’s Big Break: 370 Megawatts Of New Hyperscaler Demand In Iowa!

Alliant Energy reported first quarter 2026 ongoing earnings of $0.82 per share, representing approximately 25% of the midpoint of full-year guidance despite mild temperatures across its service territory that modestly reduced margins. The quarter reflected higher revenue requirements and Allowance for Funds Used During Construction (AFUDC) from capital investments at its Iowa and Wisconsin utilities; these positives were offset by increased operations and maintenance costs related to new energy resources and planned maintenance, as well as elevated depreciation and financing expenses. Electric sales excluding weather impact remained essentially flat year-over-year. A $0.05 per share benefit was recognized from the remeasurement of deferred tax assets due to updated state income tax apportionment assumptions tied to higher projected commercial and industrial revenues, including from data centers.
