What mid-pack City of Marietta - (GA) filings show

City of Marietta - (GA) is a municipally-owned utility operating in Georgia under EIA identifier 11646. It reports service to approximately 42,330 customer accounts and generated about $0.11 billion in annual electric revenue, with a service footprint spanning 14 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 Marietta - (GA) customer experienced 206.2 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. The SAIFI figure, which tracks average outage events per customer, came in at 2.93 for the same period, meaning customers statistically saw about 3 distinct interruptions that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 130.3 minutes, and the spread against the headline 206.2 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 Marietta - (GA), which lets you see whether reliability is trending up or down rather than judging from a single snapshot. Over that window, SAIDI moved from 487.1 down to 206.2 minutes, a trend worth noting for anyone weighing capital investment outcomes.
