Burns & McDonnell has finalized construction on two solar energy projects for Alliant Energy in Iowa, bolstering the state’s clean energy portfolio. The 150-MW Wever Solar Project in Lee County and the 50-MW Creston Solar Project in Union County will collectively power approximately 40,000 homes annually. Both projects utilized Canadian Solar 660-watt modules.

The Wever Solar Project spans 900 acres in a floodplain between the Skunk and Mississippi Rivers. Its innovative design includes flood mitigation systems and a future-ready substation capable of integrating battery storage. The Creston Solar Project overcame uneven terrain and erosion challenges near the Platte River through advanced stabilization techniques.

“These projects demonstrate our commitment to sustainability and safety,” said Jami Stone, Construction Project Manager at Burns & McDonnell, highlighting the efforts of over 420 craft workers and 326,000 hours of work.

The projects also provide environmental and community benefits, such as native plant seeding for erosion control and $30,000 raised for local charities. Both sites are undergoing Envision certification for sustainability.

“As we continue to diversify our generation resources, these projects bring clean, fuel-free energy to our customers,” said Matt Cole, Assistant Vice President at Alliant Energy.

Burns & McDonnell’s integrated EPC approach streamlined project delivery, ensuring compliance with regulations and optimizing costs.
