Electrical Aggregation

In December 2023, the Village received blind competitive bids from qualified suppliers for its electric aggregation program for the next term starting March 2024. The Village has established a program wherein ratepayers will be charged exactly the ComEd rate (including the monthly variable portion), at zero rate risk. The program benefits residents in that the Village will be provided with Renewable Energy Certificates (RECs) for a portion of their power consumption at no increased cost to residents or the Village.

Buffalo Grove is an EPA Green Power Partner Community.

NIMEC is here to help!

The village is a member of the Northern Illinois Municipal Electric Collaborative (NIMEC). NIMEC is a collaborative of 140 municipalities that band together to drive down pricing for residential and municipal electricity.

The cost of serving each electric account varies greatly. Some ratepayer accounts remain with ComEd because the cost of generation for the usage profile exceeds the ComEd rate. Others will move to supplier MC Squared Energy Services, which is headquartered in Chicago. All will pay exactly the same ComEd rate, including ComEd’s monthly variable PEA component. Notices were mailed to residents and small business owners on January 15, 2024. 


  1. Ratepayers receiving an opt out “GREEN ELECTRIC AGGREGATION NOTICE” will automatically be enrolled with MC Squared in March and will pay exactly the ComEd rate, including the monthly variable PEA, unless they choose to opt out.  If they do nothing, they will receive a Confirmation of Switch notice from ComEd in February confirming their move to MC Squared.
  2. Ratepayers receiving an “Informational Notice Only: No Action Required” are currently receiving service from MC2 and this is simply confirmation they will continue to do so.
  3. Some ratepayers enrolled with ComEd (or alternative suppliers) will receive no notice and their account will remain as-is, However, those receiving ComEd supply service are considered a part of the program, pay exactly the ComEd rate, and a portion of their consumption is offset by Renewable Energy.

No one from MC Squared, ComEd, or the Village will ever visit your home or call you to enroll.

If a solicitor claims to be the Village supplier, MC Squared, or ComEd, please take their information and report the incident to the ICC.
