About Alliant Energy
Alliant Energy is a regulated utility holding company serving electric and natural gas customers in Iowa and Wisconsin. Its two utilities, Interstate Power and Light and Wisconsin Power and Light, generate and deliver power at rates approved by state regulators, and the company grows by investing in generation and grid infrastructure.
Data centers have become the center of its growth story. Google has announced a data center project in Cedar Rapids, Iowa, and large campuses have been announced in Alliant's Wisconsin territory as well. The company cites this data center load as the key driver of its raised capital spending and load forecasts, funding new renewables, gas generation and grid capacity.
Alliant Energy was incorporated in 1981, is headquartered in Madison, Wisconsin, and employs about 2,900 people. Its shares trade on the NASDAQ.
Alliant Energy in the AI buildout
Alliant Energy operates in the Utilities & Grid layer of the AI buildout. The Midwest has become a growth region for hyperscaler data centers, and Alliant's Iowa and Wisconsin territories have both attracted announced projects, including Google in Cedar Rapids. Serving that load requires new generation and grid investment, which is exactly how a regulated utility grows earnings. Alliant supplies the power the buildout depends on, but its returns are set by regulators, keeping its AI exposure strategic rather than direct.
LNT is tracked in Utilities & Grid, rated Peripheral on the AI Exposure leaderboard.
