A home solar battery is worth it in Massachusetts more than in most states, because the battery has a paying job here. Through ConnectedSolutions, Eversource and National Grid pay you about $275 per average kW each summer to share stored power during peak events, roughly $1,200 a year for a typical home battery. Add outage backup against the state’s 30.21 cent power and pairing with SMART, and the battery earns, not just sits.
Most battery advice online is national and generic. Massachusetts is different because a home battery here can actually earn money. The state runs ConnectedSolutions, a demand-response program where Eversource and National Grid pay you to let your battery discharge during summer peak hours, when the grid is strained and power is most expensive (National Grid ConnectedSolutions battery program; Eversource battery storage demand response). That is the reason a battery in Massachusetts is a different decision than a battery in a cheap-power state. This page walks through the ConnectedSolutions math, how a battery pairs with SMART and net metering, and what backup is worth against the state’s high rate. For the full picture of going solar here, start with our Massachusetts solar guide, and for how batteries work in general, see our national guides on the best solar batteries for home backup and what a solar battery costs.
Why a home battery is worth more in Massachusetts
Because ConnectedSolutions pays your battery to work. In a typical state, a home battery is a cost you accept for backup power. In Massachusetts, the same battery can join ConnectedSolutions and earn a summer performance payment for discharging during grid peak events, on top of the backup it gives you and on top of the solar credits from net metering and SMART. Three value streams stack on one battery, which is unusual and specific to the Northeast utilities that run this program.
According to MySolarFY’s August 2026 model, a single whole-home battery in Massachusetts installed at roughly $12,000 to $16,500 can pull back about $1,200 a year in ConnectedSolutions income, locked for the first five summers, which is on the order of $6,000 over that window before you count a single outage avoided. The annual figure is simply the payment math: a battery delivering roughly 4 average kW across the summer events at about $275 per average kW works out near $1,100 to $1,200 a year, so a bigger battery that holds its output earns more and a smaller one earns less. That does not make a battery pay for itself outright, but it turns most of the cost into a resilience upgrade you are largely reimbursed for, rather than a pure expense.
Backup value is separate and personal: at Massachusetts’s 30.21 cent rate, the power you keep during an outage is worth far more than its meter price in spoiled food, a working sump pump, or heat in a storm. We do not put a fixed dollar on that, because it depends on how often your area loses power and what an outage costs your household.
ConnectedSolutions, the Massachusetts-specific battery payment
ConnectedSolutions is a demand-response program that pays you for the average power your battery delivers during summer peak events. You keep control of a reserve for your own backup, and the utility dispatches the rest during 30 to 60 events across the summer season, each up to about three hours. The figures below are what the utility program materials show as of August 2026, but program terms and rates change by filing, so verify the current numbers with your utility before you enroll.
| ConnectedSolutions term | What to verify (August 2026) | Source |
|---|---|---|
| Summer performance payment | About $275 per average kW delivered during events (Eversource and National Grid, residential battery) | National Grid, Eversource |
| Typical annual income | Around $1,200 a year on average, varying with battery size and how many events fire | National Grid battery program |
| Rate lock | The per-kW rate is locked for your first five summers enrolled | National Grid |
| Season and events | June 1 to September 30; roughly 30 to 60 events, each up to about 3 hours | Eversource |
| Who can join | Homeowners with an eligible battery on the Eversource or National Grid grid; a backup reserve stays yours | Clean Energy Group, ConnectedSolutions |
The important nuance: the payment is based on average kW delivered during events, not total kWh, so a bigger or better-configured battery that can hold up its output across a three-hour event earns more per event than a small one. Your installer sets a reserve so an event never leaves you empty. Because the rate resets by filing and the program has been expanding, confirm the current per-kW figure and enrollment terms with Eversource or National Grid before you sign anything.
How a battery pairs with SMART and net metering
A battery does not replace Massachusetts’s solar credits, it sits on top of them. Here is how the pieces fit for a solar-plus-battery home.
- Net metering does the everyday work. Massachusetts credits residential exports at a near-retail rate for systems 25 kW and under, so day to day your extra solar still offsets grid power at the high 30.21 cent rate whether or not you have a battery (Mass.gov net metering). For the mechanics, see how Massachusetts net metering and SMART pay you, or the national basics of how net metering credits your solar exports.
- SMART pays you for producing. The SMART tariff pays a solar owner a per-kWh income for 20 years, and it also offers an optional energy storage adder that pays extra for pairing a qualifying battery with the solar system. The adder value steps down by block and depends on system size and battery duration, so verify the current adder with the Massachusetts SMART storage guidance before you count on it (Mass.gov SMART 3.0; DSIRE).
- ConnectedSolutions pays the battery. This is the demand-response income above, and it runs alongside net metering and SMART rather than instead of them.
Put together, a Massachusetts solar-plus-battery home can earn from net metering, SMART, the SMART storage adder if it qualifies, and ConnectedSolutions, while still holding a backup reserve. That is a genuinely different stack than a battery in a low-rate state, where the battery only ever buys you resilience. For where these credits fit in the broader incentive picture, read the Massachusetts solar incentives breakdown, and for the cost side of the solar system itself, see Massachusetts solar cost and payback.
What a home battery costs in Massachusetts, and the value against it
Budget roughly $12,000 to $16,500 installed for a single whole-home battery in Massachusetts in 2026, before any incentives (market ranges via EnergySage Massachusetts and SolarReviews, August 2026). A common residential battery holds around 13 kWh of usable capacity and delivers about 5 to 11.5 kW of power depending on the model, enough to carry essential circuits, or a whole modest home, through an outage. We keep this vendor-neutral on purpose: match the battery’s usable kWh and continuous kW output to what you actually need to back up, and ask each installer to size the ConnectedSolutions reserve so an event never leaves you without your own backup.
| Battery value stream (August 2026) | What it is worth in Massachusetts | Source |
|---|---|---|
| Installed cost (one battery) | About $12,000 to $16,500 before incentives | EnergySage MA, SolarReviews |
| ConnectedSolutions income | About $1,200 a year, roughly $6,000 across the 5-summer rate lock | National Grid |
| SMART storage adder | Extra per-kWh income for a qualifying solar-paired battery; verify current block value | Mass.gov SMART |
| Outage backup value | Power kept during outages, valued well above the 30.21 cent meter rate; personal, not modeled | EIA, residential MA, March 2026 |
| Federal battery credit | $0 for 2026 buyers; the 25D credit ended December 31, 2025 | IRS, SEIA |
The 30% federal Residential Clean Energy Credit (Section 25D), which used to cover a qualifying home battery, ended for expenditures made after December 31, 2025, so a Massachusetts homeowner buying a battery in 2026 cannot claim it. That makes the Massachusetts-specific value, ConnectedSolutions income, the SMART storage adder, and backup, the real reason to add storage now. Solar and batteries are not free, and monthly payments apply if you finance. Savings and incentive amounts are not guaranteed and depend on your battery, usage, utility, and enrollment.

Outage backup and the case against the 30 cent rate
Massachusetts pairs a high power rate with real weather risk, coastal storms, nor’easters, and summer heat that strains the grid. A battery gives you two things at once here: it keeps your lights, fridge, heat, and sump pump running when the grid goes down, and it earns ConnectedSolutions income the rest of the summer for helping the grid avoid those peaks in the first place. Against the state’s 30.21 cent per kWh rate, among the highest residential rates in the country, the power you store and use yourself is worth more here than almost anywhere (EIA, residential Massachusetts, March 2026).
Whether backup alone justifies a battery is personal. If your street rarely loses power, the ConnectedSolutions income and the SMART storage adder carry most of the case. If you lose power often or run medical equipment, the resilience may matter more than any payment. Either way, size the battery and its reserve to your own outage risk, and confirm the current ConnectedSolutions rate and SMART adder before you commit.
Verify before you sign: ConnectedSolutions per-kW rates, the SMART storage adder, and battery pricing all change by utility filing and program year.

Frequently asked questions
Is a home solar battery worth it in Massachusetts?
More than in most states, because the battery has a paying job here. Through ConnectedSolutions, Eversource and National Grid pay about $275 per average kW each summer for peak discharge, roughly $1,200 a year for a typical home battery as of August 2026, locked for your first five summers. Add outage backup against the state’s 30.21 cent rate and pairing with SMART and net metering, and a battery earns rather than just sits. It still does not usually pay for itself outright, and savings are not guaranteed.
What is ConnectedSolutions and how much does it pay?
ConnectedSolutions is a demand-response program run by Eversource and National Grid that pays you to let your home battery discharge during summer peak events. As of August 2026 the residential battery summer performance payment is about $275 per average kW delivered, and the utilities report an average of roughly $1,200 a year per participant, with the rate locked for the first five summers. Events run June 1 to September 30, typically 30 to 60 times, each up to about three hours, and you keep a backup reserve. Verify the current rate with your utility before enrolling.
Can I get the federal tax credit on a battery in Massachusetts in 2026?
No. The 30% federal Residential Clean Energy Credit (Section 25D), which used to cover a qualifying home battery, ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a Massachusetts homeowner buying a battery in 2026 cannot claim it. The Massachusetts-specific value carries the case instead: ConnectedSolutions income, the SMART storage adder if your system qualifies, and outage backup against the state’s high power rate.
Does the Massachusetts SMART program pay extra for a battery?
SMART offers an optional energy storage adder that pays a solar owner extra per kWh for pairing a qualifying battery with the solar system, on top of the base SMART tariff. The adder value steps down by capacity block and depends on system size and battery duration, so it is not a single fixed number. Confirm the current adder value with the Massachusetts Department of Energy Resources or the Mass.gov SMART storage guidance before you count on it.
How much does a home battery cost in Massachusetts?
Budget roughly $12,000 to $16,500 installed for a single whole-home battery in Massachusetts in 2026 before incentives, based on August 2026 market ranges from EnergySage and SolarReviews. A common residential battery holds around 13 kWh of usable capacity and delivers about 5 to 11.5 kW of power depending on the model. Match the usable kWh and continuous kW to what you need to back up, and compare more than one written quote, since price depends on the battery, the install, and whether it pairs with new or existing solar.
