Massachusetts averages 8-12 significant outages per year from nor'easters, ice storms, and summer thunderstorms. Solar + battery keeps your heat pump, fridge, and lights running — and ConnectedSolutions pays you $225-$275/kW while you wait for the next storm.
Yes, if you have a heat pump. Massachusetts averages 8-12 significant power outages per year, primarily from nor'easters and ice storms. Solar panels alone shut down during outages (code requirement). A battery like the Tesla Powerwall 3 ($10,500-$12,000) keeps your heat pump, fridge, and lights running for 9-10+ hours. Better yet, ConnectedSolutions pays you $2,250-$3,163/year for letting your battery support the grid during peak demand — meaning the battery pays for itself in 5-7 years while providing storm protection every day.
Massachusetts is uniquely vulnerable to power outages. The state sits at the convergence of cold Arctic air and warm Gulf Stream moisture, creating nor'easters that dump heavy snow, ice, and high winds on aging grid infrastructure. Old-growth trees line residential streets across the state, and when ice or wind brings them down, power lines go with them.
The 2024-2025 winter season saw 14 significant outage events, including 4 major nor'easters that left hundreds of thousands of homes without power. The average outage lasted 8.2 hours — but some areas, particularly coastal and heavily wooded towns, lost power for 48-72 hours.
For homes with heat pumps, an outage in January means no heat. For homes with sump pumps, a spring outage means potential flooding. A battery backup system changes the equation entirely: your solar panels charge the battery by day, and the battery powers your critical loads through the night.

Grid-tied solar systems are required by electrical code (IEEE 1547) to shut down during power outages. This is called anti-islanding protection — it prevents your panels from energizing downed power lines and endangering utility workers. To keep your home powered during an outage, you need a battery system that can "island" your home from the grid.
Both utilities have invested in grid hardening, but Massachusetts' overhead distribution lines remain vulnerable to the combination of heavy snow/ice loading and mature tree canopy that defines New England landscapes. Underground lines are more reliable but account for a small percentage of residential distribution in most MA towns.
The right battery size depends on what you need to power during an outage. Most MA homeowners with heat pumps need at least 13.5 kWh of battery capacity. Here is how to think about it.
Total essential load: ~58 kWh/day
| Appliance | Watts | Runtime/Day | kWh/Day | Priority |
|---|---|---|---|---|
| Heat Pump (3-ton) | 3,500W | 24 hrs | 42 | critical |
| Refrigerator | 150W | 24 hrs | 3.6 | critical |
| LED Lights (10 bulbs) | 100W | 8 hrs | 0.8 | critical |
| WiFi Router | 15W | 24 hrs | 0.36 | critical |
| Phone Chargers (4) | 80W | 4 hrs | 0.32 | high |
| Sump Pump | 800W | 6 hrs | 4.8 | high |
| Electric Stove | 2,000W | 2 hrs | 4 | medium |
| Well Pump | 1,000W | 2 hrs | 2 | high |

Here is what makes MA battery ownership unique: your battery is not just sitting idle waiting for the next storm. ConnectedSolutions is a demand response program that pays you to let your battery support the grid during peak demand events. You earn quarterly payments — and you still have backup capacity reserved for emergencies.
Add SMART 3.0 battery adder ($0.04/kWh for 20 years) and storm protection value, and the battery becomes one of the best home investments in Massachusetts.
If your home has a heat pump, a battery is not a luxury — it is a necessity. Unlike gas furnaces that operate without electricity (most have electronic ignition that needs power), heat pumps are 100% electric. No power means no heat. In a Massachusetts January, losing heat for 8+ hours can mean frozen pipes, which cause $10,000-$50,000 in water damage.
A single Tesla Powerwall 3 can run a typical 3-ton heat pump in heating mode for 9-10 hours — enough to get through most overnight outages. With two Powerwall 3 units, you get 24+ hours of full-home heat pump operation, even without solar recharging (which adds unlimited daytime runtime).
Mass Save offers up to $8,500 in heat pump rebates ($2,650/ton Whole-Home). Pairing your heat pump with solar + battery + ConnectedSolutions creates a fully-electrified, storm-resilient, revenue-generating home.
Tesla Powerwall automatically monitors National Weather Service alerts. When a severe weather warning is issued for your area, it charges to 100% and holds full reserve — pausing ConnectedSolutions events until the storm passes.
Enphase IQ batteries use weather forecasting to increase battery reserve ahead of predicted storms. You can set custom reserve levels and receive push notifications about upcoming events and battery status.
Both systems let you set a minimum backup reserve (e.g., 30%). This amount is always held for emergencies, even during ConnectedSolutions demand response events. You choose your comfort level between revenue and backup security.
Solar panels alone will NOT keep your power on during an outage. By code, grid-tied solar systems shut down when the grid goes down (anti-islanding protection). You need a battery system like the Tesla Powerwall 3 or Enphase IQ 5P to island your home and keep running. With solar + battery, your panels charge the battery during the day and the battery powers your home through the night.
A typical 3-ton heat pump draws 3,000-3,500 watts. A single Tesla Powerwall 3 (13.5 kWh, 11.5 kW) can run a heat pump plus essential loads for 9-10 hours overnight. If you want 24+ hour backup or have a larger home, two Powerwall 3 units (27 kWh) will keep your heat pump, fridge, lights, and communications running for a full day even without solar charging.
ConnectedSolutions is a demand response program run by Eversource and National Grid. When the grid is under peak stress (hot summer afternoons, cold winter evenings), your battery discharges stored energy to support the grid. Eversource pays $275/kW in summer and $50/kW in winter. National Grid pays $225/kW summer and $50/kW winter. A 10 kW battery earns $2,250-$2,750 per year. You still have backup capacity reserved for storms.
No. ConnectedSolutions events are predictable and scheduled in advance (typically 1-4 hours on peak demand days). Your system reserves a minimum backup threshold that you set (usually 20-30% of capacity). During storm season, you can adjust your reserve higher or activate Storm Watch mode, which holds 100% charge when severe weather is forecast.
The average MA power outage lasts 5-8 hours, but major nor'easters can cause outages of 24-72 hours in some areas. Eversource and National Grid serve different territories with different restoration speeds. Coastal and heavily-treed areas experience longer outages. A solar + battery system sized for 12-24 hours of backup covers the vast majority of outage scenarios, especially since solar panels recharge the battery each day.
Yes, you can install a standalone battery system for backup power. However, without solar panels, your battery only charges from the grid — which means once the grid goes down, you have a finite backup window with no recharging capability. Solar + battery is the ideal combination because your panels recharge the battery every day during an extended outage. ConnectedSolutions revenue also requires solar to maximize the economics.
Generators run on propane or natural gas, which can run out during extended storms. They produce carbon monoxide (outdoor placement required), are noisy, and need regular maintenance. Batteries are silent, indoor-safe, maintenance-free, and recharge from solar. The biggest advantage: ConnectedSolutions pays you $2,250-$3,163/year with a battery — generators earn nothing. Over 10 years, that's $22,500-$31,630 in income that offsets most of the battery cost.
Modern lithium iron phosphate (LFP) batteries like the Tesla Powerwall 3 operate safely down to -4°F and are installed indoors (garage, basement, utility room) where temperatures stay well above that threshold. Battery capacity decreases slightly in cold (about 5-10% at 32°F), but this is accounted for in sizing recommendations. Massachusetts cold is well within the operating range of all major residential battery systems.
