Alliant Energy Corporation (LNT) — Business Overview

Business Description

Alliant Energy is a Midwest regulated electric and natural gas utility serving approximately 1.01 million electric and 435,000 natural gas customers across Iowa and Wisconsin through its two primary subsidiaries: Interstate Power and Light Company (IPL, Iowa) and Wisconsin Power and Light Company (WPL, Wisconsin). The company is in active transformation — retiring coal, expanding wind/solar/storage, and capitalizing on a data center boom anchored by 3 GW of hyperscaler load agreements that could drive 50% peak demand growth by 2030.

Revenue Model

As a regulated utility, Alliant Energy earns authorized returns on its rate base set by the Iowa Utilities Board and Wisconsin Public Service Commission. Revenue comes from tariff-based electric and natural gas sales to residential, commercial, industrial, and large-load (data center) customers. Capital investments in generation, transmission, and distribution earn regulated returns once approved in rate cases or via annual recovery mechanisms. The $13.4B four-year capex plan drives compounding rate base and earnings growth.

Products & Services

  • Electric distribution and transmission — Iowa (IPL) and Wisconsin (WPL) service territories
  • Natural gas distribution — local delivery to ~435K gas customers across both states
  • Renewable generation — 1,800 MW wind + 1,500 MW solar (completed 2024) + 1,000 MW storage (planned)
  • New gas-fired generation — 1,600 MW of natural gas resources planned to serve data center load
  • Data center power supply — 4 Electric Service Agreements (ESAs) totaling 3 GW with hyperscaler customers

Customer Base & Go-to-Market

Alliant serves ~1.45 million total customers across captive regulated service territories in Iowa and Wisconsin. The transformational new customer class is hyperscale data centers: 4 ESA agreements for 3 GW of load will drive 50% peak demand growth by 2030 and >60% Q1 2026 peak demand growth year-over-year. Wisconsin and Iowa's low electricity costs, land availability, and cold climate are key data center location attractors.

Competitive Position

Alliant is a regulated monopoly in its Iowa and Wisconsin service territories. It competes for capital allocation vs. utility peers but faces no direct utility competition. Iowa and Wisconsin's regulatory frameworks have been constructive — a December 2025 unanimous Wisconsin rate settlement (2026-2027) provides earnings visibility. Alliant is recognized as an S&P 500 Dividend Aristocrat with 21 consecutive years of dividend increases and 320 consecutive quarters of payments since 1946.
