MILLION$ SAVED
THOUSANDS PROTECTED
Community-scale purchasing for your electricity
Since 2011, over 150 Illinois communities have teamed up through the Central & Southern Illinois Municipal Aggregation to take control of their energy costs. By bundling thousands of homes and small commercial accounts together, your local governments create massive buying power that position them to secure better rates than any individual could get alone.
- Bulk Savings: Much like purchasing in volume at a large warehouse club, this program captures lower rates by operating at scale.
- Price Stability: It replaces market volatility with predictable, steady pricing for your home or business.
- Community-Led: This is a locally-driven initiative authorized by voters and designed to keep more money in your local economy.
Program Details
BENEFITS
- Price Stability: Your supply rate is fixed* for the entire term (typically 12 to 36 months), protecting you from the market volatility.
- Convenience & Flexibility: Enrollment is automatic. You can opt out before the program starts or leave anytime thereafter without penalties or fees. You’re never locked in.
- Locally Vetted: This voter-approved program was established under the oversight of your municipality to provide a trusted alternative for residents.
FEATURES
- Seamless Service: Your utility will continue to deliver your power and handle all repairs. You’ll still receive a single bill from Ameren or Commonwealth Edison.
- Small Business Eligibility: In accordance with state law, participation is open to small businesses with an annual usage of 15,000 kilowatt-hours (kWh) or less.
- Budget Billing: You can remain on your utility’s Budget Billing plan while participating in the program.
*While some supply contracts include and fix “capacity,” the cost to keep power plants ready to prevent outages, it’s often more wise to wait. Since these prices are set by auction, locking in rates prematurely adds unnecessary risk; waiting for finalized results ensures more accurate and prudent pricing.
