Houston residents have raised concerns about power reliability for years — and new data shows outage activity climbed sharply in several Houston-area communities this summer.
ENOUGH tracks power outage frequency month by month, so you can see what is happening in your ZIP code and how the numbers have changed over time.

CHECK YOUR ZIP CODE: ENOUGH Houston Power Outage Tracker
August brought another jump in outage activity
Here’s just a portion of what the latest data shows:
- In the Tomball area, ZIP code 77375, outage activity jumped from 4.846 in July to 5.714 in August.
- In the Cypress area, ZIP code 77433, it increased from 2.600 to 3.800.
- In north Houston, ZIP code 77086, outage activity jumped from 1.000 to 4.143.
- In the Fort Bend County area, ZIP code 77476, the reading decreased from a July peak of 7.111 to 5.056 in August — but remained elevated.
The August reading for 77375 was the highest in that ZIP code during the 13 months ENOUGH is tracking. The same is true for 77433.

The ENOUGH tracker uses outage-frequency data from Ting, a third-party company that monitors power interruptions through a network of sensors.
The numbers are not a percentage of customers who lost power. Instead, they are outage-frequency readings that allow communities to be compared over time.
Higher numbers indicate more frequent outage activity in the data.
Tomball area — ZIP code 77375
The 77375 ZIP code in the Tomball area saw outage activity remain relatively low through much of the spring before a sharp summer increase.
The reading was just 0.071 in March and 0.143 in April.
It then climbed to 1.077 in May, 1.000 in June, 4.846 in July and 5.714 in August.
August was the highest reading recorded for 77375 in the data ENOUGH is tracking.
Cypress area — ZIP code 77433
The 77433 ZIP code in the Cypress area also saw a sharp summer increase.
The reading was 0 in April, then climbed to 0.889 in May, 1.200 in June, 2.600 in July and 3.800 in August.
August was the highest reading for 77433 during the 13-month period.
North Houston — ZIP code 77086
In north Houston’s 77086 ZIP code, outage activity jumped dramatically in August.
The reading went from 1.000 in July to 4.143 in August.
The area also saw elevated readings earlier in the year, including 3.000 in April and 2.833 in May.
Fort Bend County area — ZIP code 77476
The 77476 ZIP code in the Fort Bend County area is showing a different pattern.
Outage activity reached 7.111 in July, the highest monthly reading among these four ZIP codes.
It fell to 5.056 in August, but that was still higher than most of the readings recorded during the previous year.
The ZIP code also recorded elevated readings in May at 5.421 and June at 2.778.
This isn’t the first time Houston has seen outage hot spots
ENOUGH’s tracking began after residents repeatedly raised concerns about frequent power interruptions.
In August 2025, Ting data identified several Houston-area outage hot spots.
Among them were parts of Pecan Grove and Harvest Green in Fort Bend County’s 77406 ZIP code, the Walters and Spears Road area in north Harris County’s 77014 ZIP code, the JFK and Aldine Bender area in 77032, Eagle Heights in Chambers County’s 77523 and the Klein-area Cutten Green neighborhood in 77066.
At the time, Ting reported some neighborhoods experiencing outage frequencies many times higher than the national average.
CenterPoint disputed how those numbers represented system performance, saying its data measures interruptions on the utility’s side of the meter, while Ting can detect events behind the meter as well.
That distinction is important when looking at the ENOUGH tracker.
Outages improved — then the numbers climbed again.
The latest numbers come after a period when Houston-area outage activity improved.
CenterPoint reported that its own outage numbers fell in 2025, and KPRC previously reported on that improvement as the utility entered 2026.
But by spring and summer 2026, the Ting data showed significant increases in some communities.
May was a particularly notable month. Ting data showed Houston had the highest outage frequency among U.S. cities that month, according to KPRC’s previous reporting.
Then came the summer increases now visible in the ENOUGH tracker.
CenterPoint says it is investing heavily in the grid
CenterPoint says it has been making major investments to improve reliability through its Greater Houston Resiliency Initiative.
As of July 2026, CenterPoint said it had installed more than 75,500 stronger poles, cleared more than 13,000 miles of higher-risk vegetation, undergrounded more than 850 miles of power lines and installed more than 750 automation and intelligent grid-switching devices.
The company says those improvements are intended to reduce the frequency and duration of outages and help the system withstand severe weather.
CenterPoint’s own community progress tracker was updated with data through Aug. 31, 2026.
CenterPoint has also said it evaluates reliability over longer periods rather than judging its system based on one month of outage data.
Why can the numbers look different?
Two key data sources explain the difference.
Ting uses a network of sensors to detect power interruptions, including events that can happen inside a customer’s home or business.
CenterPoint measures interruptions on the utility’s system — what the company describes as the equipment on its side of the meter.
CenterPoint has previously said this difference can result in Ting reporting more interruptions than CenterPoint’s own system data in some ZIP codes.
That doesn’t make either number a substitute for the other. They measure different things.
The ENOUGH tracker is designed to show the pattern in outage activity over time, while also giving residents a way to see how their community compares with others.
What should you do if your neighborhood keeps losing power?
Start by checking the pattern.
Check your ZIP code in the ENOUGH tracker and look back month by month.
If you see repeated spikes, keep track of your own outages, including:
- The date and time your power went out
- How long the outage lasted
- Whether the outage was momentary or extended
- Whether your neighbors experienced the same problem
- Any flickering, surges or other electrical issues
CenterPoint’s official outage tracker can provide current outage information, estimated restoration information and a way to report an outage.
ENOUGH is keeping watch
Power reliability isn’t just about whether the lights are on right now.
It’s about whether residents can count on the grid day after day — especially after CenterPoint has made major investments aimed at improving reliability.
That’s why ENOUGH will continue tracking the data.

Outage data is sourced from Ting Labs. The data measures power interruption activity detected through its network and is different from CenterPoint Energy’s utility-reported outage data.
