Margaret Mary Cancer Center Embraces Geothermal in Indiana

The Margaret Mary Health Cancer Center’s new state-of-the-art 126,000 square foot facility, currently under construction, will utilize geothermal energy for its HVAC system.

The project saved up to $300,000, and the hospital will see a 6-year return on investment using clean, firm geothermal energy.

In May 2025, Margaret Mary Health (MMH) successfully completed the installation of a high-performance geothermal system at its Outpatient & Cancer Center that will cut natural gas energy costs by 80 percent, provide more reliable power to the community and significantly reduce carbon emissions. Federal clean energy tax credits totaling $413,046 proved critical for the planning and completion of this project. The Outpatient & Cancer Center also expects to save an additional $220,000 of the total cost through utility savings, a key component of the project’s financial strategy that has resulted in a remarkable five-year return on investment.
