City of Calhoun - (GA) is a municipally-owned utility operating in Georgia under EIA identifier 2812. It reports service to approximately 5,695 customer accounts and generated about $0.04 billion in annual electric revenue, with a service footprint spanning 2 ZIP codes. Municipal ownership means a local board or city council typically oversees this utility, and it is exempt from federal income tax.
In 2023, the average City of Calhoun - (GA) customer experienced 91.8 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. The SAIFI figure, which tracks average outage events per customer, came in at 0.91 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 21.3 minutes; the difference from the headline 91.8 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 Calhoun - (GA)'s reliability record can be judged on trend rather than one isolated year. Over that span, SAIDI rose from 59.1 to 91.8 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
