What short-outage Tampa Electric Co filings show
Tampa Electric Co is an investor-owned utility operating in Florida under EIA identifier 18454. It reports service to approximately 834,144 customer accounts and generated about $2.96 billion in annual electric revenue, with a service footprint spanning 136 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.
In 2023, the average Tampa Electric Co customer experienced 82.6 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That keeps this utility below the typical 120–180 minute national benchmark, consistent with a well-hardened distribution system and fast restoration crews. Over the same period, SAIFI (outage events per customer) was 1.42, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 60.7 minutes, the gap between that figure and the headline 82.6 reveals how much weather, not day-to-day infrastructure, drove outages.
Tampa Electric Co 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 79.5 to 82.6 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
Based on this utility's own EIA Form 861 reliability record -- baseline (major-event- excluded) outage duration, total outage duration, and outage frequency -- each benchmarked against every reporting utility nationwide. Not a measure of electricity rates or customer service, which this portal does not track.

Revenue per customer and outage minutes are independent figures: paying more does not guarantee fewer outages.
