What do batteries cost right now?
EnergySage publishes town-level battery prices from quotes on its marketplace. Two Greater Boston examples, both updated October 18, 2026:
| Town | Per kWh | 13 kWh system | Typical range |
|---|---|---|---|
| Hingham | $1,222 | $15,889 | $13,506 to $18,272 |
| Hyde Park (Boston) | $1,550 | $20,150 | $17,128 to $23,172 |
These are marketplace averages, not a statewide figure, and they move from month to month. Treat them as a starting point.
What changes the price?
- Storage size. More kWh costs more in total. Savant Power Storage starts at 20 kWh per unit and scales up.
- Whole home or selected circuits. Backing up everything takes more storage and more inverter power than backing up essentials.
- Electrical work.Panel space, a second panel for backed-up circuits, conduit runs and where the battery sits all change the electrician's labor.
- Control. Adding circuit modules so the battery only carries what matters can let a smaller battery do the job.
- Solar. Adding solar at the same time adds panels and coordination with your solar installer.
How can control lower the cost?
A battery sized to run everything at once is expensive. A battery that runs the essentials while load management keeps the pool heater, the EV charger and the second dryer off can be much smaller. That is the idea behind Savant Power: modules decide what the battery carries. Read how much battery backup a home needs to size by loads.
How does that compare with other backup?
For context, the standby generators we offer in Massachusetts usually run $7,500 to $20,000, installed. At the top of the market, RoseWater Energy systems, which condition every circuit with zero transfer time, usually fall between $125,000 and $1,000,000. Savant Power is what we recommend for homes that want batteries and circuit control on a budget below the RoseWater range. Savant Power Modules typically run $2,000 to $10,000, and Savant battery backup runs $10,000 to more than $100,000, depending on the size of the house and what you want backed up.
