Communities to See Lowest Aggregation Rates Since Inception

MT. VERNON – Residents of nearly one hundred Southern Illinois communities, including Mt. Vernon, have received letters from Homefield Energy confirming their enrollment in the new electric aggregate rates.

The Collinsville-based energy company was the winning bidder with a rate of 4.391 cents per kilowatt-hour (kwh). The new rate will be effective after December meter readings and is a stable, fixed rate through June 2022.

Jeff Haarmann, Partner in the Southern Illinois Aggregation, said the rate represents the lowest negotiated since the initial aggregation rates and terms took effect in 2013.


In 2012, Mt. Vernon residents voted to participate in bulk negotiated electricity rates, administered by the City and managed by the Southern Illinois Aggregation Partnership (SIAP). Participants in the aggregation rates are automatically enrolled unless they choose to opt-out, without penalty.

Haarmann said nothing changes with billing or service either.


For those wishing to continue participation, nothing is required.  The letters circulating in the community are a confirmation of the enrollment in the new rates.  A follow-up letter from Ameren will be additional confirmation of the program.

If you have any questions, contact Mt. Vernon’s city hall at 242-5000 or Affordable Gas & Electric at 203-8328.
