Use your Battery Storage Device to Make the Grid More Sustainable
The ConnectedSolutions offering uses batteries to make the grid more sustainable by reducing peak energy use which reduces air pollution and lowers electricity cost.
Eversource’s customers should use the application available on Eversource’s website.
How it Works
By enrolling your home or small business battery system in ConnectedSolutions you’ll earn incentives for allowing us to draw energy stored in your battery during times of peak electricity demand to help balance out the electric grid and avoid the use of energy from “peaker plants.”
Earning incentives is easy. Your Mass Save Sponsor will automatically send a signal to the inverter that controls your battery when energy is needed. Most battery owners will never even notice an event.
Your Mass Save Sponsor will call upon your battery no more than 60 times per summer with each event lasting a maximum of 3 hours. Summer events will occur on non-holidays between June 1 and September 30, between the hours of 2:00 p.m. and 7:00 p.m.
What's the incentive?
In return for your participation, your Mass Save Sponsor will pay $225 per kilowatt (kW) for your battery’s average contribution during summer events.
Different batteries can contribute different amounts over the 2 or 3-hour events. For a typical battery capable of a 5-kW continuous contribution during these events, customers would receive $1,375 per year of participation through the ConnectedSolutions program.
Please consult your inverter manufacturer or installer to help estimate how your battery system would perform and what annual incentive you should expect.
Which Battery Storage Systems Qualify?
You can participate in this offering either by installing a battery storage system with a new solar panel system, adding a battery storage system to an existing solar panel system, or installing a stand-alone battery storage system for your home or small business.
A device called an inverter will control your battery. Some inverters are integrated into a battery as a single unit, and some a separate device. The inverters supported by this offering are:1
 These systems may not be available for your utility. Refer to your Sponsor's website for more information ↩
Customers are eligible to apply for 0% financing through the HEAT Loan Program for the material and labor costs associated with installing a battery storage system to participate in ConnectedSolutions. The HEAT Loan cannot be used to cover the cost of the solar PV or the cost to use setup your battery system for backup power. If you are interested in receiving an authorization form which can be brought to participating lenders to apply for a HEAT Loan, please mark the appropriate field on your ConnectedSolutions application. Please consult your installer or inverter manufacturer for more details.
