Sierra Pacific Power Co, NV

Outage length, and what it means for a generator
At an average of 1.9 hours per outage, most interruptions here end before a fuel generator would even be worth starting up. Why outage length, not count, picks the backup: how often vs how long.
What this means for buying a generator
Serving 400,458 customers here, Sierra Pacific Power Co customers lose more power than most of the country sees, so a generator is worth getting rather than an overreaction.
Where this number comes from
Sierra Pacific Power Co filed these numbers itself, as an investor-owned utility, under EIA Form 861 - a federal reliability report covering its entire Nevada territory, serving 400,458 customers here, not a single street or outage.
