Shrewsbury Electric & Cable Operations is one of Massachusetts' most unique MLPs — providing electric, cable TV, and internet. Here's what solar really looks like for SELCO 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.
Shrewsbury Electric & Cable Operations (SELCO) is unique among Massachusetts MLPs. In addition to electricity, SELCO provides cable television and high-speed internet to Shrewsbury residents. This triple-play model keeps all utility revenue local, funding infrastructure and keeping rates among the lowest in the state at ~$0.15/kWh.
Located in central Massachusetts adjacent to Worcester (National Grid territory), Shrewsbury offers the benefits of suburban living — larger lots, newer developments near Lake Quinsigamond, and a lower cost of living than eastern MA — while enjoying some of the state's most affordable electricity. SELCO has been proactive about renewable energy, making solar interconnection straightforward.
SELCO is one of Massachusetts' 41 municipal light plants (MLPs). Unlike Eversource or National Grid, it's publicly owned and locally governed. This means lower rates — but also different solar incentive eligibility.
How solar economics compare across the utilities in and around Shrewsbury — Worcester (National Grid) is right next door.
| Metric | SELCO | Eversource | National Grid |
|---|---|---|---|
| Electric Rate | ~$0.15/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 | ~$55-65K | ~$85-100K | ~$95-115K |
The trade-off: SELCO customers pay ~50% less per kWh than National Grid neighbors in Worcester. 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 $55-65K.
Here's what a typical 12.5 kW residential solar system costs and saves for a SELCO customer in 2026.
Even without the federal ITC or SMART incentives, solar is a sound long-term investment for Shrewsbury homeowners. Here's why.
Even at $0.15/kWh, rates rise over time. Solar locks in your generation cost at $0/kWh for 25+ years. SELCO has adjusted rates in recent years — solar hedges against future increases and provides long-term certainty.
Studies show solar adds $15,000-$20,000 to home value in Massachusetts. Shrewsbury's larger suburban lots in newer developments are ideal for solar, and the home value boost makes it a smart capital improvement.
Since SELCO 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 for your home.
Shrewsbury has embraced sustainability, and SELCO has been proactive about renewable energy. Going solar reduces your carbon footprint by ~7-9 tons of CO2 annually and supports the community's clean energy goals.
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. Shrewsbury's larger suburban lots and newer developments often have excellent solar potential.
Obtain at least 3 quotes from MA-licensed solar installers. Compare $/watt, equipment (panels, inverters), warranties, and production estimates. Ask about MLP experience.
Notify Shrewsbury Electric & Cable Operations at (508) 841-8500 about your solar plans. They'll explain their interconnection process and net metering policy.
Your installer handles Shrewsbury building permits and electrical inspections. Typical timeline: 2-4 weeks for permits, 1-3 days for installation.
After installation, SELCO 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 SELCO bill immediately.

With the 25D tax credit gone, here are the three main ways to finance a Shrewsbury 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.
Common questions from Shrewsbury homeowners considering solar.
No. Shrewsbury Electric & Cable Operations (SELCO) is an independent municipal light plant (MLP) that serves Shrewsbury. It is NOT part of Eversource, National Grid, or any investor-owned utility. SELCO is unique among MLPs because it also provides cable television and high-speed internet — making it a "triple play" municipal utility. SELCO sets its own rates, policies, and net metering rules independently.
SELCO's rate is ~$0.15/kWh, significantly lower than National Grid in neighboring Worcester (~$0.32/kWh) or Eversource (~$0.28/kWh). Lower rates mean less savings per kWh you generate. Additionally, SELCO 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. SELCO 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 SELCO at (508) 841-8500 for current policy details.
Yes, but it's a longer-term investment. At current rates, a 12.5 kW system saves ~$1,900-2,100/year, paying back in 17-19 years with $55,000-65,000 in total 25-year savings. Solar also adds $15,000-20,000 to home value, protects against rate increases, and supports Shrewsbury's sustainability goals. If you plan to stay in your home long-term, it makes financial sense.
SMART 3.0 (Solar Massachusetts Renewable Target) is funded by investor-owned utilities — Eversource, National Grid, and Unitil. Municipal light plants like SELCO 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.
Batteries make sense for backup power and resilience, but NOT for ConnectedSolutions income (SELCO 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.
Worcester is National Grid territory at ~$0.32/kWh — more than double SELCO's rate. Worcester homeowners qualify for SMART 3.0 ($0.03/kWh for 20 years) and ConnectedSolutions battery payments. Their payback is 6-8 years vs. Shrewsbury's 17-19 years. However, Shrewsbury residents already pay significantly less for electricity month to month. Solar is a longer payback in Shrewsbury but you start from a lower cost baseline.
