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.
The following systems, and others, may be eligible for custom incentives:
- Custom lighting systems and controls
- Pumping systems
- 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.
An engineering study, performed by an experienced energy engineer qualified by Western Massachusetts Electric, is a fundamental element of the custom incentive process.
- In existing facilities, the study uses billing and metering data to ascertain the energy performance of current equipment or processes and quantifies the potential for improvement.
WMECO 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:
Up to 50% of cost of upgraded equipment, or an amount that buys down the cost of the project to a 1.5 year simple payback
Up to 50% of project costs to a maximum of $100,000
