Massachusetts’s Unitil offers multiple energy efficiency programs for their commercial and industrial customers. Special offerings under the Small Business Services program are available to business customers with average monthly demands less than 100 kW. Unitil performs a free technical assessment of the facility and develops a comprehensive energy efficiency proposal including detailed equipment specification, project costs, energy savings analysis, and project payback. Approved measures include: high efficiency lighting, HVAC equipment, air compressors, efficient motors, variable speed drives, refrigeration and controls, and customized projects. There is a 1-year warranty on all installed equipment. Interested customers should contact their local Business Services Representative at 978-353-3270.

Unitil offers rebates to Mulit-Family and Large Business customers as well. Unitil provides comprehensive engineering services including project development, detailed project costing (equipment and labor), energy savings analysis and project payback. After the project is complete, Unitil will conduct post-installation metering/verification inspections to ensure quality installations and verify project energy savings. Custom rebate amounts are up to 50% of project costs, while pre-approved incentive amounts are available for high-efficiency equipment. Similarly to the Small Business Services program, approved measures include: Premium efficiency motors, variable frequency drives, HVAC equipment, lighting and lighting controls, building shell measures, and process improvements. An application can be found on the program website.
