Custom incentives are available for projects that demonstrate the use of natural gas more efficiently than industry practices and/or more efficiently than the minimum building code requirements. Incentives are provided at $1.50 per first year therm saved covering up to a maximum of 50% of project costs, capped at $75,000 per site and/or per project. Custom incentives are classified as either Level One or Level Two depending on size and complexity of the project. Customers should refer to their website to see what kinds of projects qualify for each level.
The Commercial High Efficiency Heating Program offers rebates ranging from $200 to $12,000 for various types of energy efficient space and water heating equipment. Rebates depend on equipment type and efficiency. All equipment must meet certain energy efficiency standards provided on the website listed above. National Grid will also finance 50% (up to $10,000) of the cost incurred as part of an approved energy efficiency engineering study. The study must be completed by a certified energy manager or professional engineer.
