Cook County officials announced Tuesday, Aug. 1, the first power purchase agreement for renewable energy.
The agreement was reached as part of a broader transaction with Constellation and Swift Current Energy. Starting in March 2025, Cook County’s asset portfolio will source approximately 24% of its electricity, about 49,000 MWh, from a new, off-site solar project in Illinois.
Greenhouse gas emissions savings in today’s terms will be the equivalent of powering 4,733 households each year. In the first year, this energy will cover 100% of the electricity use at 18 Cook County owned-and-operated buildings including health clinics, office buildings, highway maintenance facilities, public safety buildings and warehouses.
The agreement will span 12 years, with the ability to add in new buildings as energy is reduced.
“Any time we can achieve our sustainability goals, while also bringing economic development to our communities, we consider it a huge step forward,” Cook County Board President Toni Preckwinkle said. “The co-benefits secured for this agreement mean investment in jobs, training, and domestic manufacturing, and the energy savings and environmental effects are monumental. I am proud that Cook County is a leader for not just sustainability, but in agreements that benefit the community as well.”
Cook County will receive energy and renewable energy certificates (RECs) to match the energy use at 18 county owned-and-operated buildings, including health clinics, office buildings, highway maintenance facilities, public safety buildings and warehouses as part of a long-term agreement with Constellation.
Construction of the solar project started in March 2023 and will support 450 Illinois construction jobs, approximately 18 of which will be directly from Cook County’s portion of the project.
With this agreement, Cook County is meeting several Clean Energy Plan goals such as helping reduce greenhouse gas emissions equivalent to the energy use of 4,733 households each year, according to U.S. EPA greenhouse gas equivalencies.
Cook County has achieved a 44% greenhouse gas reduction to date from a 2010 baseline, meaning less renewable energy needs to be purchased to meet the Clean Energy Plan commitment for electricity to be 100% renewable by 2030 for county owned-and-operated buildings.
The remainder of the county’s goal for building electricity use to be 100% renewable by 2030 will be met by energy efficiency projects, on-site solar installations, and future off-site renewable energy agreements.
