Chilmark could pursue three levels of resiliency
most resiliency would be achieved with a full microgrid. This involves powering the town hall, fire, and EMS buildings with solar energy, adding a battery, and connecting all of these features in a microgrid.
could also choose to simply outfit the buildings for solar energy and add a battery. Adding a battery for the buildings could lower electricity costs for solar energy, and would add resilience for outages of up to 48 hours
path of least resiliency, which would provide one to four hours of backup power in the event of a power outage.
With a battery, 15 diesel generators down-Island, used during peaks in power, could also be discontinued.
