Ameren Illinois - Energy-Efficiency Program
Illinois Power Co. commercial energy efficiency rebate program
program summary
Ameren Illinois provides a wide range of financial incentives to help businesses reduce energy use, lower costs, and create safer, more efficient environments. These incentives support upgrades in lighting, HVAC systems, water-saving devices, weatherization, specialty equipment, and smart thermostats. Programs are available for both new construction and existing buildings, with options including networked lighting controls, ground source heat pumps, compressed air improvements, and high-efficiency food service and refrigeration equipment.
