Green Mountain Power's BYOD (Bring Your Own Device) program pays differently from ConnectedSolutions: ~$95 per kWh of enrolled capacity per year (up to $950 for a 10 kWh battery). This per-kWh structure rewards battery capacity rather than power output, making larger batteries proportionally more valuable. GMP is the most battery-forward utility in New England, with more residential batteries per capita than any other utility in our service area.
Program details
Green Mountain Power's BYOD program is structured differently from ConnectedSolutions — it pays approximately $95 per kWh of enrolled capacity per year (up to a $950 annual cap for a 10 kWh battery). GMP uses the enrolled capacity for grid services. This is Vermont's flagship residential VPP.
GMP's BYOD program uses enrolled batteries for grid services year-round — not just during summer peaks. GMP dispatches batteries for frequency regulation, peak shaving, and renewable integration. This broader use case is why BYOD pays per kWh (capacity) rather than per kW (power): GMP values the total energy available for grid services, not just the instantaneous power. Enrolled batteries are managed through GMP's grid platform, which communicates with Tesla, Enphase, and other battery cloud systems. Payment is monthly (unlike annual ConnectedSolutions payments in other states), providing steady cash flow.
Real enrollment example
Karen and Steve Lindgren in Stowe installed a Tesla Powerwall 3 (13.5 kWh) in November 2024 — timed intentionally to catch winter dispatch events that seasonal programs in other states miss entirely. NuWatt submitted BYOD enrollment to GMP three days after PTO. GMP activated the battery within two weeks — faster than any other utility in our service area. Their first monthly BYOD credit appeared on the December bill: $79.17. That same credit repeated every month through the following year. By November 2025, they had earned $950 in BYOD credits. Unlike ConnectedSolutions' lump Q4 payment, the Lindgrens see steady monthly income that offsets their electric bill directly.
On a -8°F January morning, GMP dispatches for frequency regulation at 6:40 AM as electric heating load surges across northern Vermont. The Lindgrens' Powerwall begins discharging 5 kW — but the house stays warm because their heat pump draws from the grid while the battery exports. By 9:15 AM the event ends. GMP also calls a shorter afternoon peak-shave event at 4:30 PM lasting ninety minutes. This year-round dispatch pattern is unique to Vermont: while MA and CT batteries sit idle from October to May, the Stowe Powerwall earns every month. Solar recharges the battery by noon on clear winter days; on overcast days, overnight grid charging fills the gap.
Vermont's year-round BYOD dispatch changes the solar pairing math significantly. In summer, a 9 kW array fully recharges the battery after each event using free sunshine. In winter, solar production drops 60-70%, and the battery relies more on grid charging at GMP's $0.21/kWh rate. Over a full year, solar recharging saves $130-180 vs grid-only — a larger absolute number than seasonal states because the battery cycles year-round. The real advantage: GMP BYOD pays $950/year regardless of recharge source, so solar doesn't increase VPP revenue directly. Instead, it reduces the cost of each discharge cycle, boosting net profit from $770/year (grid-charged) to $900-950/year (solar-paired).

VPP revenue estimates use published program rates from utility tariff filings and ConnectedSolutions program reports as of 2026. Actual payment depends on the number of events called, your battery’s performance during events, and ongoing enrollment. Rates change quarterly — re-run this calculator before making financial decisions. This is informational, not a guarantee of revenue.
NuWatt installs VPP-eligible batteries across all 9 service states. We handle the ConnectedSolutions / BYOD enrollment paperwork as part of the install.
Start my free battery quoteGMP BYOD pays approximately $95 per kWh of enrolled battery capacity per year, capped at $950 for a 10 kWh battery. A Tesla Powerwall 3 (13.5 kWh) earns the $950 cap. A smaller Enphase IQ 5P (5 kWh) earns $475/year. The per-kWh structure means that if you install two batteries (27 kWh total), you earn $950 × 2 = $1,900/year — the cap applies per battery, not per household. This is unique among NE VPP programs.
Three key differences: (1) Payment structure — BYOD pays per kWh of capacity vs per kW of power output. A battery with high capacity but modest power output earns more in BYOD than in ConnectedSolutions. (2) Year-round dispatch — BYOD uses batteries for grid services all year, not just summer peaks. (3) Monthly payments — GMP pays monthly BYOD credits on your bill, while ConnectedSolutions pays annually in Q4. Monthly payments improve cash flow for financed installations.
Yes. GMP BYOD supports Tesla Powerwall, Enphase IQ Battery, Franklin aPower 2, and SolarEdge Home Battery. GMP's platform communicates with each manufacturer's cloud. NuWatt installs all four in Vermont. The GMP-branded battery lease (Tesla Powerwall at $0/month) is a separate program from BYOD — customer-owned batteries enrolled in BYOD generally earn more over 10 years because you keep the ITC and avoid lease restrictions.
GMP BYOD is only available to GMP customers (73% of Vermont). Vermont Electric Cooperative (VEC) and Washington Electric Cooperative (WEC) do not participate. For coop customers, battery economics rely on the federal 30% ITC and limited TOU savings only. No VPP revenue. If you are in coop territory, set VPP to $0 in the calculator for realistic numbers. VEC has discussed a pilot program but nothing is confirmed for 2026.
Yes. Vermont net metering credits solar production at retail rate, and BYOD pays separately for battery capacity enrollment. The two programs do not overlap or conflict. A solar + battery installation in GMP territory can collect: net metering credits ($0.20-0.24/kWh for exported solar), BYOD revenue ($950/year per 10 kWh battery), federal 30% ITC, and TOU arbitrage. This combined stack produces a 7-9 year payback in GMP territory.
GMP has been using residential batteries as grid assets since 2017 — longer than any other utility in our service area. CEO Mari McClure has publicly stated that distributed batteries reduce GMP's need for expensive peaker plants and transmission upgrades. GMP treats residential batteries as a lower-cost alternative to utility-scale infrastructure. This economic alignment (your battery saves GMP money) is why they pay competitive BYOD rates and actively promote residential storage.
