Section 25D Expired December 31, 2025 — No Federal Battery Tax Credit for Homeowners
Homeowners who purchase a Tesla Powerwall with cash or a loan receive $0 in federal tax credits. Third-party owned solar+battery systems (PPA/lease) can still claim Section 48/48E (30%) through July 4, 2026 — the financing company claims the credit, not the homeowner.

Enter your town above to see which Tesla Powerwall incentive program you qualify for
Massachusetts has two separate Tesla Powerwall VPP programs. Which one you qualify for depends entirely on your electric utility.
Eversource + National Grid
Best for: High-revenue battery owners. A single Powerwall 3 can earn $18,500–$21,900 over 5 years with ConnectedSolutions.
Municipal Utilities (18 towns)
Best for: Municipal utility customers who have zero other battery incentive options. $1,350 upfront + $3,600 over 10 years = $4,950 total per Powerwall.
Unitil Customers: No Battery DR Program
Unitil Energy (Fitchburg, Lunenburg area) does not participate in ConnectedSolutions or any battery demand response program. A Tesla Powerwall still provides backup power and solar self-consumption benefits, but there are no utility payments for grid support in Unitil territory.
These 18 Massachusetts municipal utilities currently participate in the NextZero Connected Homes Tesla VPP program. More MLPs are joining each year — Concord was the latest addition in 2025.
Source: MMWEC/NextZero press releases and Tesla support pages, verified February 2026. If your municipal utility is not listed, contact them directly — more are joining.
Municipal utility customers have historically been excluded from battery incentive programs like ConnectedSolutions. MMWEC NextZero changes that — here's how it works.
NuWatt installs your Powerwall (we handle permitting, interconnection, and enrollment). Any Powerwall model qualifies. Powerwall 3 gets the highest upfront incentive ($1,350).
Your MLP enrolls you in the NextZero Connected Homes program. Enrollment is done through the Tesla app or your utility. NuWatt handles the paperwork for you.
When your utility calls a VPP event (peak demand), your Powerwall discharges excess energy to the grid. Your backup reserve (20% minimum) is always protected. Events happen during high-demand periods.
You receive $90 in quarterly utility bill credits for each enrolled Powerwall. That's $360/year. Over the 10-year program, you earn $3,600 per Powerwall.
| Incentive | Amount | When |
|---|---|---|
| Upfront incentive (PW3) | $1,350 | At enrollment |
| Quarterly bill credits (Year 1) | $360 | 4x $90 |
| Years 2–10 credits | $3,240 | 9 years × $360 |
| Total (10 years) | $4,950 | Per Powerwall |
Two Powerwalls = $9,900 in total program value over 10 years. Plus backup power, solar self-consumption, and TOU arbitrage value not counted here.
If you have a municipal utility, you've been locked out of battery incentive programs for years. Here's what changed.
Both programs accept Tesla Powerwall 2 and Powerwall 3. Here's how earnings compare.
| Feature | Powerwall 2 | Powerwall 3 |
|---|---|---|
| Capacity | 13.5 kWh | 13.5 kWh |
| Continuous Power | 5 kW | 11.5 kW |
| Integrated Inverter | No | Yes |
| ConnectedSolutions (Eversource/yr) | ~$1,625 | ~$3,738 |
| ConnectedSolutions (NGrid/yr) | ~$1,375 | ~$3,163 |
| MMWEC Annual Credit | $360 | $360 |
| MMWEC Upfront Incentive | $100/kWh (up to $2,000) | $1,350 |
| Backup During Outages | Yes | Yes |
Key insight: For ConnectedSolutions, Powerwall 3 earns roughly 2.3x more than Powerwall 2 because you're paid per kW of capacity (11.5 kW vs 5 kW). For MMWEC NextZero, both models earn the same annual credits — but Powerwall 3 gets a dedicated $1,350 upfront incentive.
A Tesla Powerwall works best paired with solar. Here's why the combination is more valuable than either alone.
Store excess solar during the day, use it at night. Go from ~60% self-consumption to 85-90% with a battery.
Your Powerwall keeps critical loads running during outages. Solar recharges the battery during daytime outages for extended backup.
Earn $360–$4,388/year depending on your program. The VPP only dispatches surplus — your backup reserve is always protected.
A Virtual Power Plant is a network of home batteries (like Tesla Powerwalls) that work together to support the electrical grid during peak demand. When the grid needs extra power, your Powerwall discharges stored energy. You get paid for participating. In Massachusetts, there are two VPP programs: ConnectedSolutions for Eversource/National Grid customers, and MMWEC NextZero Connected Homes for municipal utility customers.
It depends on your electric utility. If you have Eversource or National Grid, you qualify for ConnectedSolutions. If you have a municipal utility (like Reading, Hingham, Peabody, etc.) that participates in MMWEC, you qualify for NextZero Connected Homes. If your municipal utility has not yet joined MMWEC, or if you have Unitil, there is currently no battery demand response program available to you. Use the town lookup tool on this page to find your program.
With ConnectedSolutions (Eversource): a single Powerwall 3 (13.5 kW) can earn up to $4,388/year ($275/kW summer + $50/kW winter). With National Grid: up to $3,713/year ($225/kW + $50/kW). With MMWEC NextZero: $360/year per Powerwall in quarterly bill credits, plus a one-time $1,350 upfront incentive for Powerwall 3. ConnectedSolutions pays significantly more per year, but MMWEC is the only option for municipal utility customers.
No. Each program is tied to your utility. ConnectedSolutions is exclusively for Eversource and National Grid customers. MMWEC NextZero is exclusively for participating municipal utility customers. You cannot switch programs without switching utilities, which would require moving to a different town.
Not for homeowner purchases. Section 25D (the 30% residential clean energy credit) expired December 31, 2025. If you purchase a Powerwall with cash or a loan, the federal tax credit is $0. However, if a Powerwall is part of a third-party owned solar+battery system (PPA or lease), the financing company can claim Section 48/48E (30%) on systems beginning construction before July 4, 2026.
During a VPP event, your Powerwall discharges stored energy to the grid to help meet peak demand. Your backup reserve (default 20% for MMWEC, adjustable for ConnectedSolutions) is always maintained — the VPP will never drain your battery below this level. Events are limited: ConnectedSolutions caps at 60 hours/year, and MMWEC events are called only when the grid needs capacity. Your home is protected first.
Yes. NuWatt Energy is a Tesla Certified Installer for Powerwall. We handle the full process: site assessment, permitting, installation, utility interconnection, and enrollment in your VPP program (ConnectedSolutions or MMWEC NextZero). We serve all of Massachusetts — both IOU territory (Eversource, National Grid) and municipal utility towns.
Yes. Tesla Powerwall 3 is compatible with most existing solar installations. Adding a battery to an existing solar system lets you store excess daytime production for evening use, provides backup power during outages, and earns VPP revenue. NuWatt can assess your existing system and recommend the right configuration. A solar+battery system maximizes both self-consumption and VPP earnings.
More Massachusetts municipal utilities are joining MMWEC NextZero each year — Concord joined in 2025, for example. If your MLP is not yet participating, contact your utility and ask about battery incentive programs. A Tesla Powerwall still provides backup power and solar self-consumption benefits even without a demand response program. You can enroll in NextZero later when your utility joins.
Powerwall 3 has a higher continuous power output (11.5 kW vs 5 kW for Powerwall 2), which means it can contribute more capacity during VPP events. For ConnectedSolutions, more kW = more money — a Powerwall 3 at 11.5 kW earns roughly 2.3x what a Powerwall 2 earns per event. For MMWEC NextZero, the credit is per-Powerwall ($90/quarter), not per-kW, so the earnings are the same regardless of model. However, MMWEC's upfront incentive is $1,350 for Powerwall 3 specifically.
