It reports service to approximately 11,417 customer accounts and generated about $0.03 billion in annual electric revenue, with a service footprint spanning 1 ZIP code.

In 2023, the average City of Shelbyville - (TN) customer experienced 57.1 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. SAIFI, the average number of outage events per customer, was 0.79 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Once major event days (hurricanes, ice storms) are excluded, SAIDI comes down to 19.7 minutes, and the spread against the headline 57.1 indicates how much weather, versus routine infrastructure, drove the outage total.
