Grid reliability · 2024 · 1 reporting utility

Power outages in Rhode Island

The utilities that reported here serve 509,231 customers between them, not the whole state. Weighted by customer count, they averaged 61 min without power in an ordinary year and 104 min once major events are counted. Each figure comes only from the filers that published it, and the counts are below.

Read this as one filing, not a survey

Only 1 utility in Rhode Island published interruption metrics for 2024, and the thinnest figure on this page rests on 1 filing. The figures describe that utility and should not be treated as a state-wide measurement.

What it means

Why there are two numbers

Across the utilities that filed both figures, major events account for 42% of the outage time Rhode Island recorded once they are counted: 104 min against 61 min without them, a factor of 1.7×. 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 1 utility that filed both figures, which is all of them, 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 Rhode Island’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 1 filing and the storm-inclusive average from 1 filing, out of 1 filing that published an outage figure at all. Those are the same utilities on both sides. 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.
