Power reliability at Unitil Energy Systems
New Hampshire's record with Unitil Energy Systems: 1.4 outages in the most recent filing year, 1.6 hours without power in total, modestly better than the national norm. That is 57% less outage time than the New Hampshire state average of 3.9 hours a year.
Outage length, and what it means for a generator
Outages here typically run short, about 72 minutes before power is back - a battery power station or small portable generator should cover the essentials through most of them. Why outage length, not count, picks the backup: how often vs how long.
What this means for buying a generator
Serving 80,020 customers here, Outages at Unitil Energy Systems run below the national norm, so a generator is not urgent - still worth checking if you have medical equipment or a sump pump that cannot go without power.
Where this number comes from
Unitil Energy Systems filed these numbers itself, as an investor-owned utility, under EIA Form 861 - a federal reliability report covering its entire New Hampshire territory, serving 80,020 customers here, not a single street or outage.
