Unitil - Commercial and Industrial Energy Efficiency Programs

June 18, 2010


Massachusetts’s Unitil offers multiple energy efficiency programs for their commercial and industrial customers. The Small Business Services program offers rebates to its business customers with average monthly demands less than 100 kW for improving energy efficiency in their facilities. 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, efficient motors, refrigeration and refrigeration controls, and customized projects. There is a 1-year warranty on all installed equipment. For all other business customers, Unitil offers the Large Business Services program. 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. Rebate incentives are up to 50% of project costs or a pre-approved incentive amount equal to the incremental cost of the efficient equipment above standard equipment. Approved measures include: Premium efficiency motors, lighting and lighting controls, HVAC and building shell measures, and process improvements. An application can be found on the program website. Unitil, as a member of GasNetworks, also offers the high efficiency heating equipment rebates program. This program offers commercial and industrial customers rebates from $25 to $1,000 for the installation of qualified high-efficiency gas-fired space and water heating equipment. Eligible equipment includes programmable thermostats, windows, furnaces, boilers, and water heaters. All equipment must meet energy efficiency requirements listed on the website.
