Alliant Energy Corporation (LNT - Free Report) benefits from a diversified generation portfolio comprising natural gas, coal, wind, solar, hydropower and energy storage. The company’s electricity generation mix in 2025 comprised 36.9% natural gas, 28% wind, 22.8% coal, 8.5% solar, 1% hydroelectric power and 2.8% other sources. This diversified energy mix combines dispatchable generation with renewable resources to support electricity supply and system reliability.

Alliant Energy plans to invest $13.4 billion in capital projects from 2026 to 2029 to expand generation, renewable energy, energy storage and utility infrastructure, supporting its long-term earnings per share (EPS) growth target of 5-7%. Its generation strategy includes approximately 1,600 megawatts (MW) of new natural gas capacity, 1,300 MW of renewable generation and 1,000 MW of energy storage through 2029. 

Alliant Energy’s diversified generation portfolio supports growing electricity requirements, including demand from data centers, while serving a broad customer base across its service territory. 

The diversified portfolio also helps LNT manage the challenges associated with changing fuel prices, weather patterns and electricity demand.

This balance is particularly important as electricity demand evolves and the company continues to invest in cleaner energy resources.

Overall, the diversified generation portfolio provides Alliant Energy with greater operational flexibility, a broader range of energy sources and a pathway to balance reliability, cost management and environmental goals.
