Electrical Aggregation Program

Under Montgomery's municipal electrical aggregation program, the Village of Montgomery went out to bid in June 2015 and has selected Constellation as the energy supplier for the coming two years at a rate of 6.82¢ per kWh compared with ComEd's rate at that time of 7.13¢ per kWh.  Information on the 2015 aggregation program was mailed out to all residents on June 13, 2015 by Constellation.  FAQs on the new 2015 program can be found here.

ComEd will continue to provide the infrastructure to bring the electricity to all homes and will continue to send a consolidated bill. If you choose to use Constellation, you will still receive a bill from ComEd, but Constellation will be listed as the electricity supplier on the ComEd bill. You will not receive a separate bill from Constellation.

The phone number for Constellation is 844-830-3339.


In June 2015, the Village entered into a fixed rate aggregation contract with Constellation for 2 years at 6.82¢ per kWh. The contract rate was lower than the prevailing ComEd rate in June 2015 of 7.13¢. However, commodity prices, including electricity, have dropped since that time.  

The Village’s aggregation rate of 6.82¢ were available through May 2016.  The recent regulatory event Constellation notified residents of, included a price increase. Although our rate with Constellation was a fixed rate, this regulatory increase is allowed under our contract with them.  Therefore, the new aggregation program rate will reset to 7.364¢ per kWh in June 2016 and be available through the summer of 2017.  

As you may know, the ComEd rate is reset twice a year in May and September. The newly announced ComEd base rate of 6.275¢ per kWh is considerably lower than the Village’s electric aggregation program rate of 7.364¢ effective in June 2016. Residents would be better served by switching back to ComEd at this time. The Village’s aggregation program has no early termination fee, so any resident wanting to move to the lower ComEd rate may do so with no penalty by calling the Village’s current supplier, Constellation, at 1-844-830-3339. (Neither the Village nor ComEd can switch your account, only Constellation can.) You will need to have your ComEd account number on hand when you call.

Residents can find alternative priced rates from other suppliers and additional information regarding municipal aggregation at the State of Illinois’ website:  Any resident desiring to move to ComEd or any other supplier should contact Constellation Energy at 1-844-830-3339. Please remember to have your account number available when you place the call.  Residents can later rejoin the aggregation program at the same rate should they choose to leave. Please note the only prohibition to switching is residents are not allowed to move back to the supplier from which they left for 6 months. 

Residents with additional questions can call our electricity consultant, NIMEC, at 1-800-727-3820.
