SUSTAINABLE ENERGY PROGRAM
2026
Why should you invest in energy efficiency?
The Sustainable Energy Program (SEP) provides financial incentives to encourage residential and business customers to make energy-efficient improvements. By investing in energy efficiency, you help reduce peak demand, power costs, wasted energy and associated emissions.
How does the program work?
Funds are available on a first-come, first-served basis until December 31, 2026.
Visit LES.com/SEP to see the available incentives, program terms and conditions, and the list of participating contractors.
For residential projects:
- Contact one or more of the SEP participating contractors for bids and available incentives.
- Once you accept and sign a quote from one of the participating contractors, they will submit the project to LES on your behalf if it qualifies for an incentive.
- You will receive an LES credit on your invoice from the contractor.
For commercial projects:
Reach out to >SEP@LES.com for instructions on how to apply. Note: Pre-authorization is required prior to the purchase or installation of qualifying equipment.
