Alliant Energy Solar Program
Purpose
The Alliant Energy Wisconsin Solar Program represents one of the Midwest’s largest renewable energy initiatives, advancing the company’s goal of achieving net-zero greenhouse gas emissions from its utility operations by 2050. Partnering with Burns & McDonnell, the program added 866 MWdc of clean energy across nine utility-scale solar sites in Wisconsin, capable of powering approximately 174,000 homes annually. The initiative underscores Alliant Energy’s and Burns & McDonnell’s shared commitment to delivering sustainable, reliable and cost-effective energy solutions.
Impact
This transformative program not only advances Alliant Energy’s clean energy transition but also strengthens Wisconsin’s local economies. The project created more than 1.6 million solar modules, 300,000 steel piles, and over 1.8 million labor hours, supporting 1,300 craftworkers and 300 apprentices. In addition to power, these facilities offer long-term economic and financial benefits to the local communities. Beyond energy generation, the program’s design embraced environmental stewardship. Native vegetation and pollinator-friendly plantings were integrated to promote soil health, biodiversity, and aesthetic value across all sites. Burns & McDonnell and Alliant Energy followed the Envision Sustainability Framework, and all nine sites were awarded Platinum Envision ISI verification, the highest distinction for sustainable infrastructure.
