Commercial and Industrial (C&I) Custom Program

The C&I Custom Program incentivizes tailored energy efficiency and distributed generation projects that require site-specific engineering analyses and/or projects with energy conservation measures that are not otherwise covered by the C&I Prescriptive Program incentives. Funding levels range from a minimum of $10,000 to a maximum of $1 million per customer. Additional restrictions apply. For further details, please refer to the C&I Custom Program’s project descriptions below.

Examples of customers who have participated in the C&I Custom Program include hospitals, manufacturers, universities, commercial bakeries, food processors, office complexes, and data centers. To learn more about past custom projects, click here.
