Grinnell Solar Park projects underway

City of Grinnell, Grinnell College, Mayflower Community and Ahrens Park Foundation partner with Alliant Energy on 5 MW of solar projects

GRINNELL, Iowa (April 18, 2024) – Alliant Energy, with four Grinnell community partners, has broken ground on multiple solar projects that will total 5 megawatts (MW), at the new Grinnell Solar Park on the west side of the city.

Alliant Energy will own, operate and maintain the Grinnell Solar Park as part of its Alliant Energy® Customer-Hosted Renewables program.

“This new solar park showcases the benefits of renewable energy and a new source of reliable energy for the community,” said Amanda Accola, senior key account manager for Alliant Energy. “We’re appreciative of the forward-looking partners that made these four projects possible.”

The four community partners will each have their own solar projects nestled within the park. The City of Grinnell and Grinnell College will both have 2-MW projects. Mayflower Community and Ahrens Park Foundation will have a 625-kilowatt (kW) and a 375-kW facility, respectively.

The solar park will be located south of 6th Avenue at the intersection of Bliss St. on a brownfield site, formerly commercial or industrial land where environmental factors may limit future development opportunities. The community has worked closely with the Iowa Department of Natural Resources for many years to clean up the property and perform environmental testing.

“The city of Grinnell appreciates the collaboration with the other project participants and the leadership provided by Alliant Energy. The revitalization of this underutilized brownfield site was made possible by the work of the Grinnell School District and the Iowa Department of Natural Resources. Their work eliminated an abandoned and dilapidated nuisance industrial facility, paving the way for these improvements,” said Russ Behrens, Grinnell City Manager. “The collaborative work results in the generation of 5 megawatts of clean, renewable energy and meaningful revenue for the participants. The net revenue for the city of Grinnell over the potential 35-year life span is more than $3 million to support projects such as emergency medical services and streets.”

"As we break ground on the Grinnell Solar Park, we're not just constructing panels; we're illuminating a path toward a more sustainable future,” said Chris Bair, Grinnell College Environmental and Safety Manager. “This collaborative effort between Alliant Energy and our incredible community partners signifies a commitment to harnessing the power of renewable energy. Together, we're not only generating clean power but also empowering our community with the resources to thrive for generations to come.

Alliant Energy expects the Grinnell Solar Park will be operational in early 2025.

The park is another important component in Alliant Energy’s Clean Energy Blueprint, the company’s roadmap to diversify its energy mix and accelerate its transition to renewable energy. The company’s Clean Energy Vision includes a goal of net-zero greenhouse gas emissions from its utility operations by 2050.

“Mayflower Community is pleased to join Alliant Energy and project participants in the development of the Grinnell Solar Park,” said Kellie McGriff, Executive Director of Mayflower Community. “Mayflower is enthusiastic about partnering with the City of Grinnell to preserve and protect our environment and natural resources and support vital local projects.”

“The Ahrens Park Foundation is honored to be participating in the Grinnell Solar Park, with collaborative efforts with Alliant Energy and our local partners. The advantages that this solar project bring to our community are significant, as it has the potential to stimulate our local economy, enhancement of health and well-being, preserving our environment, reduction in utility expenses, as well as understanding and education around how solar works,” said Chad Nath, President and CEO of Ahrens Park Foundation. “Heeding the wise words of Claude W. Ahrens, we are dedicated to leaving it better than we found it and have consistently acted upon this advice by providing spaces for individuals to lead a healthy and well-rounded life.”
