New England's grid takes a beating every year — nor'easters in winter, ice storms in spring, heat-wave demand spikes in summer. A home battery provides automatic backup power when the grid fails, and earns money the rest of the year through utility demand-response programs. Paired with solar, a battery stores the surplus your panels generate during the day and discharges it when you need it most — at night, during peak-rate hours, or when the grid is down. See our full battery storage services and solar services for what each covers individually.
Automatic Backup Power
When the grid goes down, your battery system automatically isolates your home and switches to backup power — seamlessly, in milliseconds, without any manual action. A standard home battery system keeps essential loads running for 4 to 12 hours depending on consumption. If your solar panels are generating during the day, they continue charging the battery through an extended outage, extending backup duration indefinitely under the right conditions.
Your Battery Earns Money
ConnectedSolutions is a demand-response program run by Eversource and National Grid in Massachusetts and Rhode Island Energy in Rhode Island. By enrolling your battery and allowing the utility to draw a small amount of stored power during peak summer demand events — typically 30 to 60 times per year from June through September — you earn an annual performance payment. Massachusetts homeowners earn approximately $275 per kW of battery capacity per year over a 10-year program term.
RI ConnectedSolutions Details
Rhode Island Energy's ConnectedSolutions program runs June 1 through September 30, with 30 to 60 grid events per season typically lasting 2 to 4 hours each. RI homeowners typically earn $225 to $250 per average kW of battery performance — translating to $1,000 to $1,500 annually for a standard home battery. Smart battery software maintains a backup power reserve throughout, so grid events never leave you without emergency power. See our Rhode Island solar page for the full RI incentive picture.
CT Energy Storage Incentives
Connecticut offers state-backed Energy Storage Solutions rebates for residential battery installations — upfront incentives plus ongoing performance payments through Eversource or United Illuminating for allowing the utility to dispatch your battery during peak demand events. Connecticut's electricity rates are among the highest in the country, making battery storage one of the strongest financial plays in the state. See our Connecticut solar page for the full program stack.
Up to $10,500 Upfront in VT
Green Mountain Power's Bring Your Own Device (BYOD) program pays Vermont homeowners $850 to $950 per kW of stored energy capacity upfront — typically $9,000 to $10,500 for a standard home battery — in exchange for allowing GMP to draw on stored power a few times per month during peak demand. GMP also manages the battery before forecasted storms, ensuring it's fully charged for backup. A 10-year battery lease is also available at $55 per month or a one-time $5,500 payment.
Battery Maximizes Solar Value in RI
Rhode Island Energy credits surplus solar exports at 80% of the retail rate — meaning exported kilowatt-hours are worth less than self-consumed ones. A battery solves this directly: store your midday solar surplus and use it at night at the full retail value instead of exporting at a discount. Combined with ConnectedSolutions enrollment and the REF battery adder, Rhode Island is one of the strongest battery markets in New England. See our solar and heat pump page for the full electrification picture.

GMP also manages pre-storm charging to ensure backup readiness. A lease option is available at $55 per month or a $5,500 one-time payment for homeowners who prefer not to purchase outright.
- Maine — Efficiency Maine Storage Programs Efficiency Maine supports battery storage as part of whole-home electrification projects, particularly when paired with heat pumps and solar. Paired with the Net Energy Billing (NEB) solar program through CMP or Versant Power, battery storage extends the self-consumption value of solar production. See our Maine services page for the full picture.
- Federal Incentives — Confirm at Filing Federal clean energy incentive programs for residential battery storage have been subject to legislative changes. When battery storage is installed alongside a new solar system, potential federal incentive eligibility may apply — confirm current program status with your tax advisor at time of filing. We provide all necessary documentation regardless of incentive structure.
Three Reasons New England Needs Battery Storage
Backup resilience, solar value maximization, and demand-response income. Each reason stands on its own — together they make battery storage one of the strongest home energy investments in the region.
The Battery System
Wall-mounted home battery storage systems — including the Tesla Powerwall 3 and Enphase IQ 5P — install in a garage, utility room, or exterior wall. Each unit provides approximately 13 to 15 kWh of usable storage capacity. Most New England homes install one or two units depending on backup load requirements and demand-response program targets. Fully installed by our licensed electrical crews.
When the Grid Goes Down
When a nor'easter or ice storm takes out the grid, your battery system automatically switches to backup mode — powering refrigerators, heating systems, medical equipment, lights, and Wi-Fi while neighbors are in the dark. If your solar panels are generating during the day, they continue charging the battery through an extended outage. No generator noise, no fuel, no manual intervention required.
Paired with Solar
Battery storage captures the surplus your solar panels generate at midday and stores it for evening use — shifting self-consumption from the lowest-value export window to the highest-value household use window. In Rhode Island, where net metering exports at 80% of retail, this is a direct financial improvement. Pair solar, battery, and a heat pump for the complete New England electrification stack with every incentive program activated.

Solar Battery Backup FAQ
A single standard home battery — such as a 13.5 kWh Tesla Powerwall 3 or Enphase IQ 5P — typically powers essential home loads for 4 to 12 hours depending on what you're running. Essential loads (refrigerator, lights, Wi-Fi, phone charging, and a small heating or cooling load) consume far less than a whole-home load, so runtimes at the longer end are realistic for most New England homes.
If your solar panels are generating during daylight hours of the outage, the battery continues to recharge — effectively extending backup duration indefinitely through a multi-day storm as long as there's any sun. The system manages this automatically, prioritizing backup reserve and recharging from solar before exporting to the grid or participating in demand-response events.
Yes — if your system includes backup capability and an automatic transfer switch, it isolates your home from the grid during an outage and switches to battery power seamlessly. The transfer happens in milliseconds. Your solar panels continue generating and charging the battery during daylight hours, so the system can sustain critical loads through extended outages without any fuel or manual action.
The key distinction is between "backup-enabled" and "grid-tied only" systems. A grid-tied solar system without battery backup shuts off during a grid outage by code — it cannot feed into a dead grid. A battery backup system operates as an independent microgrid for your home during the outage period. We design for backup capability on every New England battery install.
Yes — and the New England case is stronger than most regions for three specific reasons. First, the grid here takes significant seasonal stress from nor'easters and ice storms, making backup power genuinely valuable rather than theoretical. Second, demand-response programs in Massachusetts, Rhode Island, and Connecticut pay real annual income for enrolled battery systems — offsetting the battery investment through program payments over 5 to 10 years. Third, high regional electricity rates mean every kWh of stored solar energy used at home is worth more here than in lower-rate markets.
Vermont homeowners have an additional incentive: Green Mountain Power's BYOD upfront rebate of up to $10,500 makes the battery investment economics among the strongest in the country. The combination of backup value, demand-response income, and self-consumption optimization makes battery storage a clear yes for most New England homeowners who are also installing solar.
ConnectedSolutions is a utility-backed demand-response program available to battery storage owners in Massachusetts and Rhode Island. By enrolling, you allow the utility to draw a small amount of stored energy from your battery during peak electricity demand events — typically the hottest summer afternoons when grid stress is highest. The events last 2 to 4 hours and occur 30 to 60 times per year between June and September.
In exchange, Massachusetts homeowners earn approximately $275 per kW of battery capacity per year over a 10-year program term. Rhode Island homeowners earn $225 to $250 per kW per season — typically $1,000 to $1,500 annually. Smart battery software maintains a minimum backup reserve throughout all events, so you're never left without emergency power during participation. We handle ConnectedSolutions enrollment as part of every battery install in MA and RI.
Yes — Green Mountain Power's Bring Your Own Device (BYOD) program pays Vermont homeowners $850 to $950 per kW of battery storage capacity upfront, typically totaling $9,000 to $10,500 for a standard home battery system. This is one of the strongest upfront battery incentives in the country. In exchange, GMP can draw on your stored power a few times per month during peak grid demand periods.
GMP also actively manages your battery before forecasted storms — automatically charging it to full capacity before a nor'easter or major weather event so it's ready to provide backup power. For homeowners who prefer not to purchase a battery outright, GMP also offers a 10-year lease program at $55 per month or a one-time $5,500 payment. We handle BYOD program enrollment for every Vermont battery install.
The most widely installed home battery systems in New England in 2026 are the Tesla Powerwall 3 and the Enphase IQ 5P — both are compatible with ConnectedSolutions in MA and RI, the GMP BYOD program in Vermont, and CT's Energy Storage Solutions program. Both offer approximately 13 to 15 kWh of usable capacity, seamless solar pairing, automatic backup switching, and smart grid management software.
The right system for your home depends on your existing solar inverter setup, your backup load requirements, how many units you need, and which utility demand-response program you're enrolling in. Some programs have an approved "Bring Your Own Battery" equipment list — we confirm compatibility with your specific utility and program before specifying equipment on every quote.
