Energy Efficiency Grant Programs

Renewable Energy Grant

Naperville’s Renewable Energy Program enables Naperville's residential and business electric customers to make voluntarily monthly donations through their electric bills to support the City’s investment in renewable energy. Through effective in-house management of the program, the City has been able to save money and is investing it back into the community through Renewable Energy Grants.

Funding for the 2019 Non-Residential Renewable Energy Grants is now available. Applications are due April 30, 2019.

IMEA Electric Efficiency Grants

The IMEA has received project applications that, if all are awarded, are in excess of our available funding and NO FURTHER APPLICATIONS are being accepted at this time. If there are future project cancellations or reduced incentive awards that make additional funding available, we will reopen application acceptance.
