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.

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).
