With Great Power4 Helmi 2025

Harvesting food and energy with agrivoltaics

Right now, there’s not much growing in Iowa. But Nick Peterson, strategic partnerships manager for Alliant Energy, is already thinking about next summer’s yields. He’s spearheading a collaboration with Iowa State University, an Alliant customer, to evaluate a practice called agrivoltaics, which marries farming with solar energy generation.

Across ten acres, the utility installed a 1.35 megawatt solar installation, using both fixed arrays and tracker panels. Along with a team from Iowa State University’s agriculture and engineering schools, Alliant Energy is looking at the potential for growing high-value crops under the panels. One year into the four-year project supported by a $1.8 million Department of Energy grant, early food and power generation results are promising.

This week on With Great Power, Nick tells Brad what scientists are learning from the project, why it could change how utilities think about agrivoltaics, and why one of the hardest parts of his job is addressing the fears some farmers have about the practice.
