Agency: 2017 saw longer power interruptions due to hurricanes, winter storms

The average U.S. electricity customer had interruptions in power totaling nearly eight hours in 2017, the U.S. Energy Information Administration said on Friday.

The number of hours without power was nearly double the average total duration in 2016, which the EIA attributed to more hurricanes and winter storms in 2017 and longer interruptions caused by major events.

Excluding major events, the average duration of interruptions customers experienced was almost identical in 2016 and 2017 — about two hours in both years. In 2017, the average customer experienced 1.4 interruptions counting major events and 1.0 interruption excluding major events, the EIA said.

Washington, D.C., New Jersey, North Dakota, Arizona and South Dakota had the shortest total time interrupted in 2017, with average interruptions ranging from 58 minutes (District of Columbia) to 95 minutes (South Dakota).

Maine, Florida, New Hampshire, Georgia and Vermont on average had the longest total time interrupted in 2017. In each of those states, the large interruption durations were caused by major events such as winter storms (in the case of Maine, New Hampshire and Vermont) or hurricanes (in the case of Florida and Georgia). The average customer interruption time in the latter five states ranged from 15 hours in Vermont to 42 hours in Maine.

Puerto Rico experienced the longest U.S. blackout in history as a result of Hurricane Maria; however, the data in this analysis does not include Puerto Rico.

TribLIVE commenting policy

You are solely responsible for your comments and by using you agree to our Terms of Service.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
