Renewable Energy Program

The Naperville Renewable Energy Program was established in 2004 as a way for Naperville Electric Utility customers to purchase renewable energy from renewable energy resources in Illinois. The program expanded in 2012 to also fund renewable energy projects in Naperville for non-residential customers in the form of grants.

When you enroll, Naperville purchases Renewable Energy Certificates (RECs), which means that electrons generated by renewable energy sources, such as wind turbines and solar arrays, are delivered to the local electric grid, so less fossil fuels are used. The current program is comprised of 99% wind energy and 1% solar energy, generated within Illinois and in neighboring states.

In addition to purchasing RECs, the program also provides funding for renewable energy projects in Naperville.

The goals of the grant program are:

  1. To increase or create opportunities for our community to learn about renewable solutionsl;
  2. To support grant projects that measurably increase renewable energy usage and displace fossil fuels; and,
  3. To support renewable energy grant projects that can be replicated.

Non-residential customers in Naperville can apply for a Renewable Energy Grant, which is funded by the program. Grants are:

  • $50,000 maximum cost reimbursement award.
  • 50% of the applicant’s total cost of the energy improvement project. 
  • The City's grant award amount and grants from all other sources shall not exceed the total project cost.

How to Participate

An additional charge of as little as $5.00 to your monthly electric utility bill covers the added expense of delivering clean, renewable energy to the electric grid and will support funding renewable energy projects in Naperville.
