Note: Due to possible funding constraints, all rebate applications must be pre-approved before purchasing any equipment.

Groton Utilities, a municipal utility, offers incentives for commercial and industrial customers to install energy-efficient equipment in eligible facilities through several efficiency programs described in detail on the web site above. Rebates for

  • efficient lighting retrofits and vending machine controls (based on number of kilowatt-hours (kWh) saved) 
  • new energy-efficient lighting 
  • high-efficiency motors (based on the number, type, and efficiency rating of units installed) 
  • HVAC equipment (based on the system size and efficiency) 

In some cases the rebate is limited to 50% of the total project cost. Applications are available on the utility's web site, and in some cases an application must be submitted for approval before construction begins. Groton Utilities may perform a post-installation inspection at the utility's discretion.

Groton Utilities also offers cash incentives for customers who participate in the utility's Demand Response Program. This voluntary program requires customers to reduce electricity consumption when the electric system is severely constrained and the price of electricity is high. Contact Groton Utilities for more information on these incentive offerings.
