WG&E is one of the few Massachusetts utilities providing both gas and electric service. Here's what solar really looks like for WG&E 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.
Westfield Gas & Electric is one of Massachusetts' 41 municipal light plants (MLPs) and one of the few that provides both gas AND electric service. Unlike Eversource or National Grid, it's publicly owned and locally governed. This means significantly lower rates — but also different solar incentive eligibility.
How solar economics compare across different Massachusetts utilities. WG&E's rate is roughly half the IOU rates — great for your monthly bill, but it extends solar payback significantly.
| Metric | WG&E | Eversource | National Grid |
|---|---|---|---|
| Electric Rate | ~$0.14/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 | 18-21 years | 7-9 years | 6-8 years |
| 25-Year Savings | ~$45-55K | ~$85-100K | ~$95-115K |
The trade-off: WG&E customers pay ~50-55% less per kWh than IOU neighbors. You save significantly on electricity every month already. Solar payback is longer, but you're starting from a much lower baseline — and 25-year savings still total $45-55K.
Here's what a typical 12 kW residential solar system costs and saves for a WG&E customer in 2026.
Even without the federal ITC or SMART incentives, solar can be a sound long-term investment for Westfield homeowners. Here's why.
Even at $0.14/kWh, rates rise over time. Solar locks in your generation cost at $0/kWh for 25+ years. WG&E has adjusted rates in recent years — solar hedges against future increases no matter how small they seem today.
Westfield has a suburban/rural character with larger lot sizes than eastern MA. This opens up ground-mount solar as an option — ideal if your roof has shading issues, isn't oriented well, or needs replacement. Ground-mount systems can be optimally angled for maximum production.
Since WG&E 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 — especially valuable in western MA where storms can cause extended outages.
Westfield sits in the Pioneer Valley with excellent solar exposure. The Connecticut River valley terrain and Westfield's relatively open landscape mean less hillside shading than more mountainous parts of western MA. Annual solar irradiance is comparable to the rest of the state.
The process is straightforward. MLP interconnection is often faster and simpler than IOU territory.
Confirm your roof (or ground area) has adequate south/southwest exposure, is structurally sound, and has minimal shading. Westfield's larger lots make ground-mount a viable option if roof conditions aren't ideal.
Obtain at least 3 quotes from MA-licensed solar installers. Compare $/watt, equipment (panels, inverters), warranties, and production estimates. Ask about experience with MLP interconnection.
Notify Westfield Gas & Electric at (413) 572-0100 about your solar plans. They'll explain their interconnection process and net metering policy. WG&E staff are accessible and responsive.
Your installer handles Westfield building permits and electrical inspections. Typical timeline: 2-4 weeks for permits, 1-3 days for roof-mount installation (ground-mount may take slightly longer).
After installation, WG&E 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 WG&E bill immediately.

With the 25D tax credit gone, here are the three main ways to finance a Westfield solar installation in 2026.
Best for: Homeowners with available capital who plan to stay 10+ years. Lower Westfield home costs mean solar represents a larger % of home value — making ownership especially important.
Best for: Homeowners who want ownership benefits without large upfront cost. Compare credit union rates — local western MA credit unions may offer competitive solar loan products.
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 Westfield homeowners considering solar.
Westfield Gas & Electric Department (WG&E) is a municipal light plant (MLP) that provides both electricity AND natural gas to Westfield residents. It's one of Massachusetts' 41 MLPs and is publicly owned by the city. WG&E is NOT part of Eversource, National Grid, or any investor-owned utility — it sets its own rates and policies independently.
WG&E's rate is ~$0.14/kWh — one of the lowest in Massachusetts, roughly half of what Eversource (~$0.28/kWh) or National Grid (~$0.32/kWh) charges. Lower rates mean less savings per kWh you generate. Additionally, WG&E customers are NOT eligible for SMART 3.0 incentive payments ($0.03/kWh for 20 years in IOU territory). Combined, these factors push payback from 7-9 years to 18-21 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. WG&E 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 WG&E at (413) 572-0100 for current policy details.
It depends on your perspective. At $0.14/kWh, the 18-21 year payback is longer than eastern MA. However, 25-year savings still total $45,000-$55,000, the system adds value to your home, and you're protected against future rate increases. If you plan to stay 15+ years and value energy independence, solar is still a sound investment. If you need fast payback, the math is harder to justify.
Whip City Solar is WG&E's own solar initiative — the utility has invested in solar projects to serve the community. This shows WG&E is solar-friendly and supportive of renewable energy. However, Whip City Solar is a utility-scale project, not a residential incentive program. You still need your own rooftop or ground-mount system to directly offset your bill.
Yes, and Westfield is actually well-suited for ground-mount solar due to larger lot sizes compared to eastern MA suburbs. Ground-mount systems can be optimally angled (typically 30-40 degrees) for maximum production and are easier to maintain. You'll need to check Westfield zoning regulations and setback requirements. Your installer should handle permitting.
Batteries make sense for backup power and resilience, but NOT for ConnectedSolutions income (WG&E doesn't participate). A Tesla Powerwall (~$10,000-12,000) or Enphase IQ Battery (~$12,000-14,000) provides 10-13 hours of backup. Given western MA's exposure to storms and potential extended outages, a battery is worth considering if energy independence is important to you.
