Large Business Programs

The Large Business program is designed for business customers with an average monthly demand of 200 kW or larger to help with the purchase of energy efficient equipment as part of a new construction or renovation project.


Large Business Customers may complete installations using in-house staff or your own vendor/contractor. You may request additional assistance by calling 603-637-4346 or by sending an email to Program applications are processed on a first-come, first-serve basis. Rebates are limited and available to qualifying applications until the program budget is depleted.

Prescriptive Incentives (New and Retrofit)

We offer rebates for the use of high efficiency chillers (new only), compressed air, HVAC (new only), lighting, motors, and variable frequency drives.

Custom Incentives

Less common installations may qualify for incentives as custom measures. Project cost and potential energy savings are quantified and evaluated through a benefit/cost model to determine eligibility.

Technical Assistance

Technical assistance by an outside engineering firm may be offered when it is necessary to quantify the energy savings potential of a proposed project. Liberty Utilities will typically fund 50% of the cost.

Availability of Funding

Generally, incentives for retrofit projects cover up to 35% of project costs. New equipment and construction incentives cover up to 75% of the incremental cost for the most efficient options. All incentives are subject to funding availability. Certain caps and restrictions apply.
