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 are able to 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. 

During the summer, batteries will be called:

  • June - September
  • 2pm -7pm
  • No more than 60 times
  • A maximum of 3 hours per event

Take the first step! Contact a battery implenter (below) or your solar installer today.

Incentives

Customers will receive an incentive every summer and winter based on the performance of their battery system. 

Summer incentive rate: $400 per kW performed per summer

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.

FAQs

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. 

No. To participate in this program, your battery storage system must be charged from an on-site renewable resource, such as a solar PV system. Customers who own a battery without a solar PV system may also participate. However, the discharge rate of the battery will be limited to the home’s energy use during events. Having a solar PV system is also required for SMART Program incentives.

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.
