What short-outage City of Gaffney - (SC) filings show
City of Gaffney - (SC) is a municipally-owned utility operating in South Carolina under EIA identifier 6894. It reports service to approximately 7,637 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 3 ZIP codes. Being municipally owned, the utility answers to a local board or city council rather than a state commission, and carries a federal income tax exemption.
In 2023, the average City of Gaffney - (SC) customer experienced 55.7 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 0.85, putting the typical customer at roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 37.8 minutes, and the spread against the headline 55.7 indicates how much weather, versus routine infrastructure, drove the outage total.
The EIA dataset includes 4 years of continuous reporting (2020–2023) for City of Gaffney - (SC), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. SAIDI has improved from 112.4 to 55.7 minutes over that window, a meaningful direction for prospective customers and regulators watching capital investment outcomes.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide.
