Electric Aggregation Referendum

Lemont residents will be asked to vote on a referendum that would authorize electric aggregation, an option under state law that allows municipalities to bundle residential and commercial accounts and negotiate with third-party suppliers for the lowest price.

The referendum will appear on on the March 20 ballot in this form:

“Shall the Village of Lemont have the Authority to arrange for the supply of electricity for its residential and small commercial retail customers who have not opted out of such program?”
