Rebate not to exceed project cost.
A customer is eligible for the following maximum rebate per service address per calendar year for equipment installed in that calendar year. A service address is the physical address at which electricity is provided.
- $10,000 in air source heat pump or air-to-water heat pump rebates or
- $15,000 in ground source heat pump rebates or
- $15,000 in rebates if a combination of air source and ground source heat pumps are installed
If a property is sold, the new account holder’s cap resets at $10,000 (ASHP or AWHP) or $15,000 (GSHP) per service address per calendar year, regardless of rebates awarded to previous account holders.
Rebate cannot be combined with a National Grid/Mass Save rebate for the same equipment.
Rebate Eligibility for Multiple Buildings per Service Address:
A customer can receive more than one whole home or partial home heat pump rebate if they have more than one non-gas heated house at a service address. Residential buildings eligible for whole home heat pump rebates must be listed as Building 1 or Building 2, etc. in the property record in the Town of Concord’s online assessment database, and must show heat fuel = oil, propane or electricity. The annual rebate caps per service address apply.
If Building 1 or Building 2 at the same service address has more than one living unit within it, each building is eligible for just one whole home rebate or multiple partial home rebates up to $10,000 ASHP/$15,000 GSHP per calendar year for the same service address. (See next section for policies governing condominium complexes and rental apartment buildings.)
The customer is not eligible for a whole home rebate for a heat pump installed in an outbuilding on their property, even if the heat pump is the sole source of heating in the outbuilding. An outbuilding is shown in the Outbuilding section of a property record in the Town of Concord’s online assessment database. Outbuildings are eligible for a rebate of $1,250 per ton up to $2,500 per building. Integrated controls are not required in outbuildings.
Rebate Eligibility for Condominium Complexes and Rental Apartment Buildings:
Heat pump rebates are available to each condominium owner for a heat pump solely serving his/her living unit, if the living unit has its own service address. Eligibility for a whole home or a partial home rebate depends on the number of units in the condominium complex and when the heat pump project planning began. If heat pump project planning had not begun by January 1, 2023, equipment installed in individual units in residential 5+ unit complexes, including 1-4 unit buildings that are part of larger complexes, are not eligible for whole-home rebates but are eligible for the partial-home rebate amounts of $1,250/ton for air-source heat pumps and $2,000/ton for ground-source heat pumps. Project planning had begun if the condo owner had requested heating/cooling coaching services or if the condo owner's installer had received a heat pump project pre-approval from Abode Energy Management before January 1, 2023. The annual cap per service address and other rebate policies apply.
Condominium associations with common area electric accounts and central heating plants serving multiple living units will be eligible for heat pump rebates under a new commercial rebate program, which will offer $2,500 - $4,500 per ton of cooling capacity, depending on heat pump type, up to $50,000 per customer every three years. Condo association common area buildings such as clubhouses, fitness centers, management offices, etc., will be eligible for heat pump rebates for those common buildings under the new commercial rebate program. In some cases, these common area buildings are classified as residential accounts in CMLP’s billing system. However, if a building owned by a condo association if a building owned by a condo association is fully or partially used for non-residential purposes, the building is eligible for a rebate under the commercial program rather than the residential program. CMLP reserves the right to determine whether an association-owned building is eligible for a residential or commercial heat pump rebate.
Customers that own rental apartment buildings will be eligible for heat pump rebates under a new commercial rebate program, which offers $2,500 - $4,500 per ton of cooling capacity, depending on heat pump type, up to $50,000 per customer every three years. The commercial rebate program and the 3-year cap apply regardless of whether each rental unit in the building has its own heating/cooling system or whether a central heating plant serves multiple living units. More details coming soon.
A "customer" is defined by a unique customer number in CMLP's billing system. In most cases, a customer with multiple accounts will have the same customer number assigned to them. However, if a business or property owner or manager has multiple customer numbers in CMLP's billing system, CMLP can, at its sole discretion, define them as a single customer.
