Mt Carmel Public Utility Co is an investor-owned utility operating in Illinois under EIA identifier 13032. It reports service to approximately 5,238 customer accounts and generated about $0.02 billion in annual electric revenue, with a service footprint spanning 7 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.
In 2023, the average Mt Carmel Public Utility Co customer experienced 234.7 minutes of power interruptions, a metric called SAIDI (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 3.24 for the same period, meaning customers statistically saw about 3 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 74.7 minutes; the difference from the headline 234.7 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), Mt Carmel Public Utility Co's reliability record can be judged on trend rather than one isolated year. SAIDI has increased from 103.7 to 234.7 minutes, which may reflect either worsening weather exposure or delayed grid modernization.
