What’s the participation incentive?
Your incentive amount is based on your state. For Massachusetts residents, the incentive rate is $275/kW average across all events. For New Hampshire and Connecticut residents, the incentive rate is $225/kW average across all events.
How many events are called during a season?
You can expect up to 60 (likely 40) events in the season which runs from June 1st – September 30th. Events will only take place on non-holiday weekdays or weekends and are for 2-3 hours between 3-8 PM.
How much can I expect to earn?
Will I receive notifications of events?
Eversource will not call events if a severe storm is forecast to ensure customers battery storage systems can be utilized for backup power if needed. In addition, some battery vendors can help you configure your system to limit how much your system will discharge during events. Please note however that this will affect how much your system will earn.
How can I ensure that I’ll still have backup energy if I need it?

Eversource will not call events if a severe storm is forecast to ensure customers battery storage systems can be utilized for backup power if needed. In addition, some battery vendors can help you configure your system to limit how much your system will discharge during events.

Can I co-participate in other programs?
  • If your battery is connected to a home solar PV system you can also earn incentives from the Solar Massachusetts Renewable Target (SMART) program administered by the state of Massachusetts. SMART requires that your battery be discharged to the grid 52 times a year to earn incentives, and discharges through ConnectedSolutions count toward this requirement.
