Before you compare: check what you're actually paying
Many Illinois communities run opt-out municipal aggregation programs that automatically enroll residents in a town-negotiated supply rate. If Bloomington runs one, the rate on your bill may be an aggregation rate rather than the Ameren Illinois Price to Compare, and that's the number a competitive offer has to beat. Check your bill before assuming you're on the utility default.

Frequently asked questions
- Who has the cheapest electricity rate in Bloomington?
- The cheapest clean, fixed-rate plan (3+ months) in Bloomington is currently 10.70¢/kWh — that's the honest headline we rank on. But the truly "cheapest" plan depends on your usage: many Bloomington plans advertise a lower number using bill credits that only apply around 1,000 kWh a month, so they aren't actually cheapest if your home uses more or less. That's why we re-rank every plan by what you'd really pay at your usage level instead of the teaser rate.

- Bloomington is served by Ameren Illinois, which delivers electricity to homes and businesses. Illinois deregulated electricity generation in 1997, meaning you can choose a different company to generate your power while Ameren Illinois continues to deliver it.
