Alliant Energy® Renewable Energy Partner

The Alliant Energy® Renewable Energy Partner program is the latest way we’ve adapted our renewable energy offerings to align more closely with our business customers’ needs.

Let us help you achieve your sustainability goals

Is your company ready to become more sustainable, and you want a partner to handle the details?

The Alliant Energy® Renewable Energy Partner program (REP) enables a large-scale customer to directly benefit from renewable generation and advance their sustainability efforts through REP agreements, and our customers can count additionality and Renewable Energy Credits (RECs) toward their sustainability index.

Why work with us?

For more than a century, Alliant Energy has helped build strong communities throughout Wisconsin and Iowa. As leaders of the renewable energy transition, we’re one of the top five largest utility owner-operators of regulated wind in the United States and the largest owner and operator of solar energy in Wisconsin.

How it works


How it works graphic

1. Alliant Energy builds and maintains a dedicated renewable energy project on the Alliant Energy® Renewable Energy Partner’s behalf with no upfront capital required from Partner.

2. The Partner signs a long-term agreement to receive the renewable attributes, like RECs, from the facility.

3. Alliant Energy manages the sale of energy to the grid and credits the value of the renewable energy and capacity to the Partner.

How does the Alliant Energy® Renewable Energy Partner benefit?

  • Meet sustainability goals: The Partner receives 100% of RECs from the project for the term of the agreement.
  • Focus on core business: The Partner works toward its sustainability goals without diverting valuable company resources to construct and maintain its own project.
  • Simplify the process: We handle construction and maintenance of the facility and buy and sell energy in the market.
  • Mitigate risk: We leverage our technical knowledge of the industry and eliminate uncertainty related to third-party developers.

What does this mean for customers and communities?

We are committed to serving our customers, which includes working toward a carbon-free future through renewable energy generation.

  • Cost neutrality: We calculate a rate for the Partner which fully covers the cost to build and operate the project. We do not pass any costs to the rest of our customers.
  • Low-cost renewables: At the end of the contracted period, we may continue to use the site to generate renewable electricity for all customers at low cost.
  • Local economy: The project will generate property tax revenue for local municipalities. Jobs created during construction and operation will increase economic activity in the area.
