What long-outage Johnson County Rural E M C filings show

Johnson County Rural E M C is a member-owned electric cooperative operating in Indiana under EIA identifier 9778. It reports service to approximately 30,727 customer accounts and generated about $0.07 billion in annual electric revenue, with a service footprint spanning 16 ZIP codes. As a cooperative, its governance is accountable to its ratepayer-members rather than shareholders, which often shapes rate-setting and reinvestment priorities.

In 2023, the average Johnson County Rural E M C customer experienced 369.6 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index). Excluding major weather events from that total, that places this utility well below the 120–180 minute national benchmark, signaling strong grid hardening and fast restoration practices. The SAIFI figure, which tracks average outage events per customer, came in at 1.74 for the same period, meaning customers statistically saw about 2 distinct interruptions that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 27.3 minutes, the gap between that figure and the headline 369.6 reveals how much weather, not day-to-day infrastructure, drove outages.

Johnson County Rural E M C has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI climbed from 97.2 to 369.6 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
