Backup Power in
Home battery backup and standby generators for Wellesley, from the Hills and Lower Falls to the neighborhoods north and south of Route 9.
Get a Savant QuoteWellesley runs its own electric utility, and in 2024 it switched on a battery built from six 20-foot battery containers next to one of its substations. That battery backs up essential town services. It does not reach into anyone's house, so a Wellesley home that needs to stay on still needs a system of its own.
Boston Backup Power is a division of Boston Automations in Norwood. We design and install RoseWater Energy systems, Savant Power and Generac and Kohler standby generators, and licensed electricians and gas fitters make the connections.

Storms and outages in Wellesley
On a Monday in April 2016, a large outage hit Wellesley Hills and Lower Falls. Police said a possible NStar supply line failure may have contributed, and the light plant worked to switch the town to an alternate power source. Even a town utility depends on the lines that bring power to it.
Tropical Storm Irene in August 2011 brought down at least 10 utility poles in town, with police estimating about 500 customers out that evening. In May 2026, residents north of Route 9 woke up on a Monday without power, with crews working around Weston Road and Route 9 and police noting it was not caused by snow.
Who supplies the power
The Wellesley Municipal Light Plant supplies the town, not Eversource or National Grid. It is a public power utility with its own outage line, and it offers residential solar rebates. Battery and solar interconnection applications for a Wellesley house go to the light plant.
Which system fits a Wellesley home?
We install all three, so we can recommend the one that suits the house and the budget.
RoseWater Energy
For a large Wellesley house where lighting scenes and the network should never drop, a RoseWater HUB carries the house through an outage with zero transfer time and conditions the power between them.
Whole-home battery backup with zero transfer time and power conditioning, for large homes where nothing can blink. Most projects run $125,000 to $1,000,000.
Standby generator
A standby generator on natural gas is a straightforward answer for a Wellesley house that wants to ride out a long outage, and it can be paired with a battery later.
A Generac or Kohler standby generator on natural gas or propane that starts on its own when the power goes out. Most installs run $7,500 to $20,000.
Where the equipment goes in Wellesley
The town's grid battery, 4.99 megawatts able to store more than 20 megawatt-hours, sits next to a light plant substation and was built with the nonprofit Citizens Energy. It is projected to save ratepayers more than $8 million over twenty years. Inside a house, the same idea works at a smaller scale: a battery cabinet in the garage or basement, sized to the circuits that matter.
Most Wellesley houses have room for a Savant Power Storage cabinet or a RoseWater HUB in a garage or a dry basement. A generator pad needs a side or rear yard spot that keeps the manufacturer's distance from windows and doors, which on smaller lots near the village takes some planning.

Questions about backup power in Wellesley
Wellesley has a town battery now. Does it keep my house on?
Wellesley has a town battery now. Does it keep my house on?
No. The light plant's battery backs up essential town services and helps the utility's costs. It does not carry individual houses through an outage. A battery or generator at your house does that.
Who handles interconnection for a battery and solar in Wellesley?
Who handles interconnection for a battery and solar in Wellesley?
The Wellesley Municipal Light Plant, since it is the town's utility. We coordinate the paperwork with them and with your solar installer.
Can a battery system fit in a Wellesley garage?
Can a battery system fit in a Wellesley garage?
Usually. A Savant Power Storage 20 sits on the floor against a wall with 36 inches clear in front, and in a garage it has to stay out of the car's path. We measure on the site visit.
