What is the difference between passive and active dispatch?

Passive dispatch will discharge up to 80% of your battery automatically during the season, on non-holiday weekdays in June, July and August from 3PM to 8PM.  You are required to opt-in to passive dispatch to receive the up-front incentives on your home battery. 

Active dispatch events can also be called during the summer, but you will have the option to opt in or decline to have your battery discharged. On days when Eversource or UI calls an active dispatch event, passive dispatch will be canceled so your battery will be called on to contribute to the grid no more than once per day.
