Grid reliability · 2024 · 20 reporting utilities
Power outages in Florida
The utilities that reported here serve 9,909,434 customers between them, not the whole state. Weighted by customer count, they averaged 67 min without power in an ordinary year and 25 hr once major events are counted. Each figure comes only from the filers that published it, and the counts are below.
What it means
Why there are two numbers
Across the utilities that filed both figures, major events account for 96% of the outage time Florida recorded once they are counted: 25 hr against 67 min without them, a factor of 22.5×. Solar panels alone do not help during an outage, because a grid-tied array shuts down when the grid does, so riding through one is a battery question. This figure will not answer it: it is an annual average across a utility’s customers, not the length or the load of any single outage. What it does say is how much of the outage time here arrives with major events rather than on ordinary days.
The comparison is drawn from the 18 utilities that filed both figures of the 20 reporting here, so both sides of the ratio describe the same set of customers. The two headline figures above are averaged over everyone who filed each one, so dividing them would not give this number.
The utilities behind the average
Each of Florida’s figures is a customer-weighted average of the filings that carried that metric, not of the table as a whole: the ordinary-year average is built from 18 filings and the storm-inclusive average from 20 filings, out of 20 filings that published an outage figure at all. Those two sets are not the same utilities, so the two columns cannot be compared filer by filer. A utility that filed without publishing a metric, or whose two major-event variants contradicted each other, is absent from that metric rather than counted as zero.

What this page is not
It is a state average of utility filings, not a measurement at any address. Each filing is itself an average over a whole service territory, so a rural feeder and a downtown network arrive here as one number, and nothing in this dataset says how far an individual address sits from it. Nothing here predicts a future year either, and a single severe storm can move a utility’s figure by an order of magnitude.
