Marist High School is proud to announce the successful completion of a major on-campus solar energy project, marking an important step forward in the school’s long-standing commitment to sustainability, environmental stewardship, and responsible leadership.
The fully installed and operational solar photovoltaic system is located on Marist’s campus at 4200 W. 115th Street in Chicago and is now actively generating clean, renewable energy for daily campus operations.
A Long-Term Investment in Sustainability
Developed in partnership with Mission Energy and constructed by 93Energy, the solar project represents a strategic, long-term investment in both environmental responsibility and operational efficiency. By transitioning a portion of its energy usage to solar power, Marist is reducing its environmental footprint while reinforcing its mission to educate students in faith, culture, and life.
The system includes 982 solar modules with a total capacity of approximately 579 kW DC. Each year, the installation is expected to generate an estimated 695,000 kilowatt-hours of electricity. Based on regional solar production averages and commercial electricity rates, this equates to projected annual energy cost savings of approximately $80,000 to $90,000.
Environmental Impact That Makes a Difference
Beyond financial savings, the solar installation delivers a meaningful environmental benefit. The system is projected to offset approximately 490 metric tons of carbon dioxide annually, an impact comparable to removing more than 100 gasoline-powered vehicles from the road each year.
“This project reflects Marist High School’s commitment to being thoughtful stewards of our resources and leaders within our community,” said David Waterman, Director of Buildings and Grounds. “The completion of this solar installation allows us to reduce our environmental footprint while providing real-world learning opportunities for our students.”
A Living Classroom for Students
In addition to powering the campus, the solar installation serves as a valuable educational resource. As a fully functioning renewable energy system, it provides students, faculty, and visitors with a real-world example of sustainability in action. The project supports hands-on learning opportunities across academic disciplines while reinforcing campus-wide sustainability goals.
