Custom Energy Solutions Program


The Right Rebate for Your Business

IID’s Custom Energy Solutions Program is designed to promote energy efficiency by offering financial incentives to commercial customers who install energy-efficient equipment. IID provides qualifying customers with technical expertise to assist in identifying energy efficiency measures and cost-saving opportunities.

The goal with all energy-saving measures is to improve the efficiency of the customer’s business facilities. Qualifying cespmeasures must retrofit, replace or upgrade old equipment with new, energy efficient technologies that exceed the applicable Title 24 energy efficiency requirements as established by the California Energy Commission or current industry standards using IID-approved project baselines (if Title 24 standards are not applicable).

Financial incentives are based on annual energy savings and are intended for the customer’s use in the purchase and installation of qualifying lighting, refrigeration, air conditioning, food service, agricultural and/or control equipment.

Incentives are based on the following cents per kWh for one year of energy savings:

kWH Energy Measure
$ 0.25 HVAC / Refrigeration
$ 0.18 Process Loads
$ 0.11 Lighting* - Interior: Office Space, Production Line, etc.
$ 0.03 Lighting* - Exterior: Off-site, Public Spaces, Parking Lots, Landscaping, etc.

*CESP will not pay incentives for the installation of incandescent, halogen, mercury vapor, probe-start metal halide, T-12 linear fluorescent or other outdated technologies when more efficient options are available. All products installed in exterior locations must be approved for outdoor use by the manufacturer. Existing fixtures must be operational in order to qualify for replacement incentives.

The program is available to commercial customers located within IID’s service area. Qualifying customers should apply for a preliminary energy analysis to determine  eligibility. For more information regarding the program, including incentives, please refer to the program guidelines.
