Insulation projects in spaces with existing, functional insulation have special qualifications. The building/space insulated must be heated with natural gas provided by CNGC. If existing insulation is damaged to the point of ineffectiveness or applied in spotty coverage, the insulation must be removed and the condition that led to the ineffectiveness/damage must be corrected before the rebate will be considered. Insulation R value must meet specifications of current CNGC tariff.
If you are planning weatherization equipment or building upgrades that do not fit within these standard incentives, but significantly reduce natural gas consumption, we may be able to offer you incentives through the custom pathway. Learn more about custom incentives.
