Houston Power Outages After Hurricane Beryl: Reading the Restoration Timeline

Establish the storm and the geographic scope

The National Hurricane Center’s Beryl record identifies the 2024 cyclone and its Texas landfall. DOE’s July 9 situation report places landfall near Matagorda on July 8 as a Category 1 hurricane. A storm category describes wind intensity; it is not itself an index of electric-system damage or restoration duration. The outage analysis needs its own operational evidence. [1] [2]

DOE reported roughly 2.8 million customer outages at the Texas peak and about 2.108 million in Texas at 2:30 p.m. EDT on July 9. These are statewide observations. They should not be relabeled as CenterPoint-only totals, Houston city totals, or numbers of individual people without power. [2]

Read restoration milestones as dated observations

CenterPoint’s archived releases record more than 1.6 million impacted customers restored by its July 13 afternoon update, 92% restoration in its July 15 evening update, and more than 98% by its July 17 late-morning update. These dated utility statements document progress within that provider’s scope, rather than establish one universal restoration time for the region. [3]

Our interpretation is that a recovery curve needs both its numerator and denominator. A cumulative number restored cannot be subtracted from a statewide peak if the two cover different providers. Likewise, a percentage of impacted customers restored is not the percentage of every customer in a city who experienced an interruption.

Why the final connections need separate treatment

CenterPoint’s Beryl archive distinguishes customers able to receive power from isolated cases involving severe property or customer-owned equipment damage. That distinction matters at the end of a restoration timeline: completion of utility work and readiness of every individual connection are not always the same event. A regional milestone should therefore retain the utility’s qualification. [3]

For an illustrative system with 10,000 affected accounts, restoring 98% would still leave 200 unresolved. That arithmetic does not estimate the Beryl remainder, because the actual impacted population and status definitions must come from the source. It shows why a headline percentage can coexist with substantial individual disruption.

What a complete Houston study would add

A more complete study would align provider-specific outage observations with actual restoration timestamps, track changes in estimated restoration times, and identify which connections remained unable to receive service. It would also distinguish the storm’s immediate footprint from later failures uncovered during restoration. The sources reviewed here do not provide all of those address-level observations.

The defensible finding is that Beryl produced a prolonged, uneven recovery whose meaning cannot be captured by a single peak. Comparing neighborhoods or judging improvements after the storm would require consistent local coverage and a defined observation window. Historical restoration milestones explain the 2024 event; they are not restoration estimates for a present-day Houston outage.

Peak impact and total burden can also move independently. In two hypothetical events with the same 1,000-account peak, immediate restoration for most customers produces less accumulated interruption time than a long plateau near the peak. Comparing the entire recovery curve is therefore more informative than comparing the highest point alone. To calculate that burden responsibly, the researcher must specify sampling intervals, treatment of missing observations, and whether new interruptions appeared during recovery.
