Get a Free QuotePeabody Municipal Light Plant has served the city since 1894. Here's what solar really looks like for PMLP customers in 2026 — no hype, just honest numbers.
The 30% federal ITC for residential solar is gone. All cost and savings figures on this page reflect $0 federal tax credit. The MA state $1,000 income tax credit still applies.
Peabody Municipal Light Plant is one of Massachusetts' 41 municipal light plants (MLPs). Unlike National Grid (which serves neighboring Salem) or Eversource, PMLP is publicly owned and locally governed. This means lower rates — but also different solar incentive eligibility.
How solar economics compare across the three utilities your neighbors may be on — Salem is just across the border on National Grid.
| Metric | PMLP | Eversource | National Grid |
|---|---|---|---|
| Electric Rate | ~$0.175/kWh | ~$0.28/kWh | ~$0.32/kWh |
| SMART 3.0 | Not eligible | $0.03/kWh (20 yr) | $0.03/kWh (20 yr) |
| ConnectedSolutions | Not eligible | $275/kW summer | $225/kW summer |
| Net Metering | ~1:1 MLP policy | ~1:1 (MDPU) | ~1:1 (MDPU) |
| Payback Period | 17-19 years | 7-9 years | 6-8 years |
| 25-Year Savings | ~$55-60K | ~$85-100K | ~$95-115K |
The trade-off: PMLP customers pay ~50% less per kWh than National Grid neighbors in Salem. You save money every month already. Solar payback is longer, but you're starting from a much lower baseline — and 25-year savings are still $55-60K.
Here's what a typical 11.5 kW residential solar system costs and saves for a PMLP customer in 2026.
Even without the federal ITC or SMART incentives, solar is a sound long-term investment for Peabody homeowners. Here's why.
Even at $0.175/kWh, PMLP rates have risen over the years. Solar locks in your generation cost at $0/kWh for 25+ years. Every rate increase from here makes your solar investment more valuable.
Studies show solar adds $15,000-$20,000 to home value in Massachusetts. With Peabody's diverse housing stock — from historic neighborhoods to newer developments — solar is a capital improvement that pays for itself.
Since PMLP doesn't offer ConnectedSolutions, batteries are still valuable for power outage protection. Tesla Powerwall or Enphase IQ add ~$10,000-$14,000 but provide true energy independence during storms.
Peabody's location on the North Shore provides solid solar irradiance. The city's mix of single-family homes with good roof access and the Route 1/128 corridor proximity makes installer access easy and efficient.
The process is straightforward. MLP interconnection is often faster and simpler than IOU territory.
Confirm your roof has adequate south/southwest exposure, is structurally sound, and has minimal shading. Most Peabody homes — from the West Peabody neighborhoods to downtown — have good solar potential.
Obtain at least 3 quotes from MA-licensed solar installers. Compare $/watt, equipment (panels, inverters), warranties, and production estimates. The Route 1/128 corridor gives Peabody excellent installer coverage.
Notify Peabody Municipal Light Plant at (978) 531-5975 about your solar plans. They'll explain their interconnection process and net metering policy.
Your installer handles Peabody building permits and electrical inspections. Typical timeline: 2-4 weeks for permits, 1-3 days for installation.
After installation, PMLP inspects the system and installs a bi-directional meter. MLP interconnection is typically faster than IOU processes — often within 1-2 weeks.
Once interconnected, your system begins producing power and earning net metering credits on your PMLP bill immediately.

With the 25D tax credit gone, here are the three main ways to finance a Peabody solar installation in 2026.
Best for: Homeowners with available capital who plan to stay 10+ years.
Best for: Homeowners who want ownership benefits without large upfront cost.
Note: A third-party system owner may claim the Section 48 commercial ITC (available through mid-2026) — this can lower your lease/PPA rate.
Section 48 Commercial ITC Note: If you choose a lease or PPA, the third-party system owner (financing company) may claim the Section 48 commercial ITC — still available for projects beginning construction before July 4, 2026. This benefit is passed through as a lower lease/PPA rate for you.
PMLP customers who want solar with no upfront cost can join the Propel waitlist for Massachusetts. Propel offers $0 down with fixed monthly payments and full ownership at year 5 — no lease, no PPA. At $0.175/kWh, avoiding loan interest is especially important for keeping solar economics positive.
Common questions from Peabody homeowners considering solar.
PMLP is an independent municipal light plant that has served the city of Peabody since 1894. It is NOT part of National Grid, Eversource, or any investor-owned utility. PMLP is one of the larger MLPs in Massachusetts, serving all of Peabody's residential and commercial customers. It sets its own rates, policies, and net metering rules independently.
PMLP's rate is ~$0.175/kWh, significantly lower than National Grid (~$0.32/kWh) which serves neighboring Salem. Lower rates mean less savings per kWh you generate. Additionally, PMLP customers are NOT eligible for SMART 3.0 incentive payments, which adds $0.03/kWh for 20 years in IOU territory. Combined, these factors push payback from 6-9 years to 17-19 years.
No. The federal residential solar Investment Tax Credit (Section 25D) expired on December 31, 2025, under the OBBBA legislation signed July 4, 2025. This applies to ALL homeowners nationwide, regardless of utility. However, the MA state $1,000 income tax credit still applies.
Yes. PMLP offers net metering at approximately 1:1 for residential solar systems. Excess generation is credited on your bill. However, MLP net metering policies are set by the utility board (not the MDPU), so terms could change. Contact PMLP at (978) 531-5975 for current policy details.
Yes, but it's a longer-term investment. At current rates, an 11.5 kW system saves ~$1,800-2,000/year, paying back in 17-19 years with $55,000-60,000 in total 25-year savings. Solar also adds $15,000-20,000 to home value, protects against rate increases, and reduces your carbon footprint by ~6-8 tons of CO2 annually.
SMART 3.0 (Solar Massachusetts Renewable Target) is funded by investor-owned utilities — Eversource, National Grid, and Unitil. Municipal light plants like PMLP are independent and do not participate in SMART. This is one of the key trade-offs of MLP territory: lower base rates but fewer state incentive programs.
Salem is served by National Grid at ~$0.32/kWh — more than double PMLP's rate. Salem homeowners get SMART 3.0 ($0.03/kWh for 20 years) and ConnectedSolutions battery incentives. Their payback is 6-8 years vs. 17-19 years in Peabody. However, Peabody residents save significantly on electricity every month already. The total lifetime savings gap is narrower than the payback gap suggests.
Batteries make sense for backup power and resilience, but NOT for ConnectedSolutions income (PMLP doesn't participate). A Tesla Powerwall (~$10,000-12,000) or Enphase IQ Battery (~$12,000-14,000) provides 10-13 hours of backup. If power outages concern you or you want true energy independence, a battery is a solid investment — especially during North Shore winter storms.
