Description

Unlike incentives for many prescriptive energy efficiency measures — such as the use of specific high efficiency lighting fixtures or water heating systems — custom incentives apply to more complex or one-of-a-kind measures that go beyond prescriptive guidelines. Custom incentives defray a significant portion of the incremental cost of high efficiency solutions.

Custom Solutions

The following systems, and others, may be eligible for custom incentives:

• Custom lighting systems
• HVAC systems
• Demand control ventilation
• Pumping systems
• Chillers and boilers
• Combustion controls
• Heat recovery
• Solar thermal systems
• Steam systems
• Building envelope
• Insulation and weatherization
• Window systems
• Energy management systems
• Process and manufacturing improvements
• Compressed air systems
• Variable speed drives
• Cogeneration systems*

*Special incentives apply to cogeneration projects.

Engineering Study

An engineering study, performed by an experienced energy engineer qualified by NSTAR, is a fundamental element of the custom incentive process. For new construction projects, the engineering study assesses the savings potential of high efficiency designs versus the minimum requirements of the state building code.

Financial Assistance

NSTAR shares up to 50% of the energy engineer’s expense to quantify potential savings. Project incentives are paid in accordance with qualifying criteria established by state regulators:

Electric:
Up to 70% of incremental cost of higher efficiency equipment, or an amount that buys down the incremental investment to a 1.5 year simple payback

Natural Gas:
Up to 50% of project costs to a maximum of $100,000
