Alliant Energy has two energy generation and distribution subsidiaries, one in Wisconsin and one in Iowa. The company has a strategic plan built upon two key elements: Growth and Optimization.
- Growth - The growth element of the strategic plan includes accelerating the growth of customers’ electric and gas usage and expanding our portfolio of energy resources to include additional clean and renewable energy.
- Optimization - The second key element of the strategic plan focuses resources on providing reliable electric and natural gas service to customers in our Iowa and Wisconsin service areas. We do this through continued modernization of the power grid, upgrades to the gas distribution system and optimization of the generation fleet.
Alliant Energy owns a portfolio of electric generating facilities operating on a diverse mix of fuels, including coal, natural gas and renewable resources. The output from these generating facilities is supplemented with purchased power.
Alliant Energy Resources is the parent company of Alliant Energy’s non-regulated businesses. The strategic plan for Alliant Energy’s non-regulated operations involves maintaining a portfolio of businesses that add to earnings but do not require significant amounts of capital.
