Officials gathered for a ribbon cutting, including Cook County Board President Toni Preckwinkle, commissioners, the Chief Engineer, Energy Manager, and Ameresco's Vice President of Business Development Steve Taggart

The solar installation consists of two arrays, totaling 1.5 megawatts (MW), located on the courthouse rooftop and on the parking garage, designed to generate approximately 1,737 megawatt‑hours (MWh) of clean electricity annually. The system is expected to offset over 50 percent of the facility's annual electricity consumption, advancing Cook County's sustainability and decarbonization goals while reducing long‑term operating costs.

"This project demonstrates Cook County's commitment to leading by example when it comes to clean energy and responsible stewardship of public facilities," said President Toni Preckwinkle, Cook County Board President. "By investing in on‑site renewable energy at the Skokie Courthouse, we are reducing emissions, lowering energy costs, and creating long‑term value for residents."

The environmental benefits of the project remain significant, particularly in the context of today's heightened focus on energy independence, cost stability, and emissions reduction. The system is projected to cut greenhouse gas emissions by approximately 722 metric tons of CO₂e annually—roughly equivalent to the carbon sequestered by more than 724 acres of forest each year. At the same time, it is expected to generate enough clean energy to match the annual electricity use of over 150 homes, helping to reduce reliance on volatile energy markets while supporting long-term sustainability and resilience goals.

"Projects like the Skokie Courthouse solar installation highlight how public sector facilities can play a meaningful role in the energy transition," said Lou Maltezos, Co-President of Ameresco. "We're proud to collaborate with Cook County to deliver a solution that supports resilience, sustainability, and fiscal responsibility while producing measurable environmental benefits for the community."

The project was developed in collaboration with Cook County's Bureau of Asset Management, with leadership and support from the County's energy and facilities teams. By leveraging underutilized space on the courthouse roof and parking structures, the installation maximizes clean energy generation without impacting daily courthouse operations.

In addition to completing the Skokie Courthouse solar installation, Ameresco has also been awarded eight additional solar projects with Cook County, further expanding the County's on‑site renewable energy portfolio. These projects, currently in the design phase, represent approximately 3.3 MW of new solar capacity and are expected to be completed by November 2027. Together, these systems will play a key role in supporting Cook County's 2030 sustainability and emissions‑reduction goals.
