Use Your Battery Storage Device to Make the Grid More Sustainable
How it Works
With the summer heat, it's important to reduce stress on the grid when possible.
ConnectedSolutions uses batteries to reduce peak energy use, reducing air pollution and lowering electricity cost.
You can participate in this program either by installing a battery with a new solar PV system or by adding a battery to an existing solar PV system. And, when the time is right, National Grid makes it easy by sending a signal directly to your battery.
Customers who have a battery without a solar PV system can participate, but will not be able to export power to the electric grid. This limits the battery discharge rate to the power the home is using at that time, reducing incentives.
In the Summer, batteries will be called:
- June - September
- 2pm - 7pm
- No more than 60 times
- A maximum of 3 hours per event
In the Winter, batteries will be called:
- December - March
- 2pm - 7pm
- No more than 5 times
- A maximum of 3 hours per event
Take the first step! Contact a battery implementer (below) or your solar installer today.
Battery implementers are:
Customers will receive an incentive every summer and winter based on the performance of their battery system.
- Summer incentive rate: $225 per kW performed per summer
- Winter incentive rate: $50 per kW performed per winter
Incentives are performance-based. Your battery system performance will vary based on size, configuration, internet connectivity, and other factors.
Some battery implementers may offer other discounts, such as a reduced upfront cost in return for paying the ConnectedSolutions seasonal incentives to the battery implementer.
Customers are eligible to apply for a zero-interest HEAT loan for the equipment and labor costs associated with installing a battery storage system. If you are interested in receiving an authorization form, please mark the appropriate field on your ConnectedSolutions application.
Please check with your battery system implementer for more details on the above.
A home battery storage system operates like a rechargeable AA or AAA battery, but at a much larger scale. Home battery systems can be discharged when needed, e.g. when the power goes out (if the system configuration supports this) or when there is a ConnectedSolutions event.
To participate in the program, customers must work with one of the approved battery implementors listed above.
Many customers install energy storage systems in preparation for power outages. We want to ensure that customers with solar batteries remain prepared if the lights go out.
In New England, most power outages occur during the winter, whereas most events in the ConnectedSolutions program will be in the summer. Additionally, if the forecast calls for extreme weather, we will not call a winter event, allowing ConnectedSolutions participants to keep fully-charged batteries in preparation for a possible outage event. Customers may also choose to participate in the summer season and forgo the winter incentive.
Yes. If we cannot communicate with your energy storage system, or if your energy storage system cannot discharge when needed (due to a maintenance issue), the incentive paid to either the system owner or their battery implementer will be affected.
Customers who don’t have a renewable energy system but do have an energy storage system that charges from the electricity grid may participate in ConnectedSolutions. However, the discharge rate of the energy storage system is limited to the instantaneous power consumption of the customer’s facility. The customer may not export power to the electrical grid. If the customer’s power draw is higher than the energy storage system maximum discharge rate at the times when demand response events are called, this inability to export to the grid will not affect the customer incentive level.
Having a solar panel system is also required for the SMART incentive program and for the federal Investment Tax Credit.
Yes. However, the ability to send excess power to the grid is limited to battery systems that are charged by renewable energy, like solar. Without the ability to send power to the grid, a battery system’s discharge rate would be limited to the power being used by the home or building at that time.
The SMART incentive program and the Federal Investment Tax credit also have restrictions on charging from the grid.
Yes. Customers with existing solar PV systems can add an energy storage system to their home to participate. However, storage cannot be easily added to every solar PV installation. Please ask your solar installer or battery implementer for more details.
When you add a battery system to your existing solar PV system, your solar interconnection agreement will need to be updated. Please work with your solar PV or battery implementer to complete this update.
