What mid-pack Gila River Indian Utility Authority (GRICUA) filings show

Gila River Indian Utility Authority (GRICUA) is a member-owned electric cooperative operating in Arizona under EIA identifier 65261. It reports service to approximately 3,369 customer accounts and generated about $0.03 billion in annual electric revenue. 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 Gila River Indian Utility Authority (GRICUA) customer experienced 160.3 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). That lands within the usual 120–180 minute national benchmark band, roughly on par with typical U.S. distribution-utility performance. SAIFI, the average number of outage events per customer, was 2.32 for the same period, so customers statistically faced roughly 2 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 160.3 minutes, and the spread against the headline 160.3 indicates how much weather, versus routine infrastructure, drove the outage total.

Gila River Indian Utility Authority (GRICUA) has 2 years of continuous EIA reporting on file (2022–2023), enough to read a real trend rather than a single-year snapshot. SAIDI has increased from 121.3 to 160.3 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
