Imperial Irrigation District, CA
Power reliability at Imperial Irrigation District

Outage length, and what it means for a generator
2.6 hours is the average length of a single outage here - past comfortable battery range, which is where a portable generator becomes the better buy. Why outage length, not count, picks the backup: how often vs how long.
What this means for buying a generator
Serving 166,111 customers here, Outages at Imperial Irrigation District 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
Imperial Irrigation District filed these numbers itself, as a political-subdivision utility, under EIA Form 861 - a federal reliability report covering its entire California territory, serving 166,111 customers here, not a single street or outage. Every other utility in California is covered too: see California's full record. How the verdict bands are set is in the methodology.
