National Grid (Nantucket) - Commercial Energy Efficiency Incentive Programs

April 16, 2007


National Grid (Nantucket) offers one program for large non-residential customers for new buildings and major renovations -- Design 2000plus -- and another program for existing facility upgrades -- Energy Initiative. Both programs offer technical assistance and rebates for various technologies including lighting and controls, HVAC systems, motors, variable speed drives and compressed air. The rebates vary greatly based on equipment efficiency and type. National Grid also offers a flexible custom rebate for energy efficient measures that are not included in the measures listed above. For the existing facilities' custom program, incentives of up to 45% of the project cost are available. For schools and for the new construction and major renovation's custom program, incentives of up to 75% of the additional cost for efficiency upgrades are available.

For small businesses (customers with an average demand use of 200 kilowatts or less, 40,300 kilowatt-hours or less, per month), National Grid offers a combined rebate and loan program for the installation of energy efficient equipment. National Grid provides a free energy audit and report of recommended energy efficiency improvements. If the company decides to make recommended improvements, National Grid will pay 80% of the cost of the installation of energy efficient equipment. The remaining 20% can be paid off in the form of a zero interest loan over a maximum period of 24 months. Eligible energy efficient equipment includes: lighting upgrades, energy efficient time clocks, photo cells for outdoor lighting, occupancy sensors, programmable thermostats, and walk-in cooler measures. Customers can register online at the website listed above for a free energy audit.
