Southwestern Public Service Co, NM
Power reliability at Southwestern Public Service Co
1.4 separate outages last year, 3.9 hours without power in total - that is Southwestern Public Service Co's record for New Mexico, running ahead of the national median. That is 36% more outage time than the New Mexico state average of 2.9 hours a year.
Outage length, and what it means for a generator
A typical outage here runs about 2.7 hours - long enough that a battery alone usually will not see you through, but short enough that a fuel-powered portable generator is a reasonable match. More on that split in how often versus how long an outage runs.
What this means for buying a generator
Serving 119,830 customers here, Southwestern Public Service Co customers lose more power than most of the country sees, so a generator is worth getting rather than an overreaction.
