What mid-pack Duke Energy Florida, LLC filings show
Duke Energy Florida, LLC is an investor-owned utility operating in Florida under EIA identifier 6455. It reports service to approximately 1,968,212 customer accounts and generated about $6.44 billion in annual electric revenue, with a service footprint spanning 415 ZIP codes. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.
In 2023, the average Duke Energy Florida, LLC customer experienced 179.7 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. SAIFI, the average number of outage events per customer, was 1.08 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 83.6 minutes; the difference from the headline 179.7 shows how much of the outage total came from weather rather than everyday grid issues.
Duke Energy Florida, LLC has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. Over that span, SAIDI rose from 126.0 to 179.7 minutes, possibly reflecting tougher weather years or grid upgrades that have not caught up yet.
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.
