I’m hearing some of those low electric rates, that were supposed to be locked in by aggregation, may not be so locked.

If you live in Bloomington, the rate signed with  Homefield Energy (Ameren) was $0.04539 per kilowatt hour.  It was signed in May 2013 and lasts for 22 months.

In Normal the rate is $0.04099 per kilowatt-hour for 17 months.  It was signed in December 2012.

Check your bills.  Is that the rate you are being charged?
