What This Utility Data Tells You

City of Rock Hill - (SC) is a municipally-owned utility operating in South Carolina under EIA identifier 16195. It reports service to approximately 40,767 customer accounts and generated about $0.11 billion in annual electric revenue, with a service footprint spanning 5 ZIP codes.

In 2023, the average City of Rock Hill - (SC) customer experienced 53.3 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. SAIFI, the average number of outage events per customer, was 0.78 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 51.9 minutes; the difference from the headline 53.3 shows how much of the outage total came from weather rather than everyday grid issues.

With 4 consecutive years of EIA data (2020–2023), City of Rock Hill - (SC)'s reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 136.9 to 53.3 minutes across that span, a direction regulators and prospective customers tend to watch closely.
