Energy Efficiency Grant Programs

Renewable Energy Grant

Naperville’s Renewable Energy Program enables 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 Non-Residential Renewable Energy Grants is available in 2020.

IMEA Electric Efficiency Grants

The Illinois Municipal Electric Agency (IMEA) has awarded the City of Naperville a three-year grant to be used for energy improvements.

Year 1 (2019): $253,882 was available for our nonresidential Electric Utility customers as incentives toward completing energy efficiency projects.

Year 2 (2020): $260,882 will be available for nonresidential customer grants for energy improvements.
