Welcome to the Central Illinois Municipal Aggregation Program!
Exclusive Offer for CIMA residents
Join your neighbors and local business owners in a community-buying program exclusively for CIMA customers. Your community has selected Constellation Energy Services, Inc (Constellation) to supply the electric aggregation program for the program term. The aggregation program offers the below rate option(s) to eligible customers.
What is Aggregation?
Aggregation allows your community to form a buying group on behalf of the citizens. By combining the buying power of its residents, the community can be more effective in negotiating rates than an individual customer might be.
Who is Constellation?

Constellation’s family of retail businesses serves residential, public sector and business customers, including more than two-thirds of the Fortune 100.
