Get a Free QuotePeabody homeowners can't use Mass Save — but PMLP runs its own program: $500/ton air-source, $750/ton ground-source, capped at 3 tons per address each calendar year and paid straight to your electric bill. The hard ton cap is the thing to plan around.
Verified against pmlp.com June 12, 2026. Federal 25C tax credit EXPIRED Dec 31, 2025.
Peabody Municipal Light Plant pays $500 per ton for an air-source heat pump and $750 per ton for a ground-source system. Rebates are capped at equipment totaling 3 tons (36,000 BTU) per address per calendar year, so the effective yearly ceilings are $1,500 air-source and $2,250 ground-source. The rebate is paid as a credit on your PMLP electric account. It applies only to owner-occupied homes, the system must both heat and cool, and a licensed contractor must install it. PMLP customers in Peabody cannot use Mass Save — this is their program instead.
Mass Save is funded by an energy-efficiency surcharge on investor-owned utility bills (Eversource, National Grid, Unitil). Peabody is served by the Peabody Municipal Light Plant (PMLP), a municipal light plant, so PMLP customers don't pay that surcharge and are not eligiblefor Mass Save heat pump rebates. PMLP runs a leaner, simpler program of its own — flat per-ton amounts with one firm rule: a 3-ton cap per address each calendar year.
| Feature | PMLP Program | Mass Save (IOU, for reference) |
|---|---|---|
| Who runs it | PMLP (processed via NextZero / MMWEC) | IOUs via Mass Save |
| Air-source rebate | $500/ton, 3-ton cap ($1,500) | $2,650/ton, up to $8,500 |
| Ground-source rebate | $750/ton, 3-ton cap ($2,250) | Varies by tier |
| Cap structure | 3 tons per address per CALENDAR YEAR | Dollar cap, effectively per project |
| Who can apply | Owner-occupied homes only | Owners + renters / landlords |
| Equipment must | Heat AND cool (no cooling-only) | Heat (cooling typical) |

Mass Save whole-home standard ($2,650/ton, up to $8,500) shown for comparison only. PMLP customers are not eligible for it; PMLP's own amounts and the 3-ton cap apply.
Two flat per-ton rates, one shared ceiling. Whichever system you choose, the rebate stops at 3 tons of equipment per address per calendar year.
Up to $1,500 at the 3-ton cap
Ductless mini-splits and ducted air-source systems both qualify. At $500/ton and a hard 3-ton (36,000 BTU) ceiling per address per calendar year, the most a single property can claim in one year is $1,500.
Up to $2,250 at the 3-ton cap
Geothermal ground-source systems earn the higher per-ton rate. Same 3-ton annual cap applies, so the effective ceiling is $2,250 — the largest single-year payout PMLP offers for a heat pump.
Federal 25C Tax Credit: EXPIRED. Section 25C ended December 31, 2025. There is $0 in federal heat pump tax credits in 2026. The PMLP bill-credit rebate is the live incentive for Peabody homeowners.
PMLP's defining rule is a ceiling on tonnage, not dollars: it rebates equipment totaling up to 3 tons (36,000 BTU) per address per calendar year. For most Peabody homes that covers the whole system in one shot. For a larger or leakier house that needs 4+ tons, the move is to phase the install across the January 1 reset so no tonnage is left unrebated.
| Your home | Install plan | Rebate outcome |
|---|---|---|
| 2-ton home (single zone or small house) | One calendar year | Up to $1,000 ASHP — fully covered Comfortably under the 3-ton ceiling. |
| 3-ton home (typical mid-size) | One calendar year | Up to $1,500 ASHP — exactly at the cap The whole system rebates in a single year. |
| 4-ton home (larger / leakier) | Phase across two calendar years | 3 tons this year + 1 ton next year The cap resets Jan 1, so the 4th ton earns its $500 in year two. |
Don't oversize to chase the cap. The right answer is always a correctly sized system for your actual heat load — an oversized heat pump short-cycles and runs less efficiently. We design to your load first, then sequence the install around the calendar-year reset so the cap works for you instead of against you.
PMLP's rules are simple but firm. Confirm all three before you sign a contract.
The rebate is reserved for owner-occupied homes. Rental units and landlord-held properties are not eligible.
Central-AC systems and cooling-only ductless mini-splits do not qualify. The system has to deliver both heating and cooling.
A licensed contractor must install the system — self-installation is not permitted.
Purchase in the 2026 calendar year, then apply through NextZero by January 31, 2027. The rebate lands as a credit on your PMLP electric account.
The rebate is for owner-occupied homes on a PMLP electric account. Rentals and landlord-held properties are not eligible. PMLP customers cannot use Mass Save heat pump rebates — this is the program to use instead.
PMLP rebates equipment totaling up to 3 tons (36,000 BTU) per address per calendar year. We right-size with a load calculation and, if your home needs more than 3 tons, plan which zones install this year versus after the January 1 reset.
Self-installation is not allowed, and the system must both heat AND cool — central-AC and cooling-only mini-splits do not qualify. The equipment must meet PMLP’s SEER2/HSPF2/COP specs (or EER2/COP for ground-source).
Purchase between January 1 and December 31, 2026, then submit the application by January 31, 2027 through NextZero (administered by MMWEC). Include your electric bill, the contractor invoice with install date, model numbers, BTU size and cost, and the AHRI certificate.
Where applications go. PMLP rebates are processed through NextZero, administered by MMWEC (Attn: Rebates, 327 Moody Street, Ludlow, MA 01056). Have your electric bill, contractor invoice, and AHRI certificate ready — the invoice must show the install date, model numbers, BTU size, and total cost.
We load-size your home and sequence the install around the calendar-year reset so no tonnage goes unrebated.
Peabody Municipal Light Plant pays $500 per ton for an air-source heat pump and $750 per ton for a ground-source (geothermal) system. Rebates are limited to equipment totaling up to 3 tons (36,000 BTU) per address per calendar year, so the effective ceilings are $1,500 for air-source and $2,250 for ground-source in any one year. The rebate is paid as a credit on your PMLP electric account. The offer applies only to owner-occupied homes, and the system must both heat and cool.
