Please note that, like all Illinois Energy Now programs, the Aggregation Program is subject to the state appropriation process, and no funds can be committed or released until a final budget is approved. In 2015, applications for the Aggregation Program were accepted under the Public Sector Energy Efficiency Program Support Guidelines and Request for Applications. Applications were due September 4, 2015.

The Illinois Department of Commerce and Economic Opportunity (DCEO) administers the Illinois Energy Now programs, including the Public Sector Energy Efficiency Aggregation Program. The program will allow public sector participants to combine energy efficiency projects in order to simplify the application process and implement projects that might otherwise be submitted as standalone projects. 

Aggregators must design a program that targets one or more public sector entities located in a ComEd, Ameren Illinois, Nicor Gas, Peoples Gas, or North Shore Gas service territories. Funded by the Energy Efficiency Trust Fund, grants will be awarded based on the applicant's ability to demonstrate cost effectiveness of the proposed program, and develop enough Energy Efficiency Projects to disperse funds and realize the savings targets within the grant period. Additional program information an application materials are available on the program web site. 

Public sector entities include municipalities, municipal corporations, local governments, public school districts, community colleges, public colleges and universities, state facilities, and federal facilities.
