Energy-efficient equipment purchased, work contracted and work completed prior to the program start date are not eligible for incentives.

Incentives are capped at up to 75% of the incremental cost per prescriptive measure and up to 50% of the incremental cost on custom measures. The incremental cost is the difference between the cost of installing a high-efficiency equipment and the cost of lower-cost standard equipment.

If a single premise exceeds $600,000 in incentives during the program year all incentives above $600,000 will be paid at 50% of the normal incentive.

Due to revisions to the Business Energy Solutions program, please note that previous program applications and worksheets cannot be used. Please download the updated application and supporting materials and submit them for your 2024 projects. Please refer to the Policies & Procedures document for a full description of program rules and guidelines.
