Sulphur Springs Valley E C Inc

What This Utility Data Tells You

Sulphur Springs Valley E C Inc is a member-owned electric cooperative operating in Arizona under EIA identifier 18280. It reports service to approximately 53,435 customer accounts and generated about $0.15 billion in annual electric revenue, with a service footprint spanning 31 ZIP codes. Cooperative ownership means the utility is run for the benefit of the ratepayer-members who elect its board, rather than for shareholder returns, which can shift how rate and investment decisions get made.

In 2023, the average Sulphur Springs Valley E C Inc customer experienced 136.7 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. That places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. Over the same period, SAIFI (outage events per customer) was 1.13, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 91.6 minutes; the difference from the headline 136.7 shows how much of the outage total came from weather rather than everyday grid issues.

Sulphur Springs Valley E C Inc has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that window, SAIDI moved from 155.7 down to 136.7 minutes, a trend worth noting for anyone weighing capital investment outcomes.
