Average customer outage minutes decreased every month in first half of 2025 compared to last year; outage minutes year-to-date are also significantly below the five-year average

Number of outages related to trees, branches and other vegetation contacting lines down about 33% compared with the same time period in 2024

Actions taken to strengthen system and improve reliability included historic investment in more storm-resistant poles, automation devices, undergrounding power lines and clearing of hazardous vegetation across service area

HOUSTON, July 23, 2025 /PRNewswire/ -- CenterPoint Energy today announced significant improvements in reliability for its Houston-area customers, with the total electric service outage minutes reduced by approximately 45% through June 30, 2025, compared to the same period in 2024. The reduction in outages or service interruptions follows the unprecedented series of resiliency actions taken by CenterPoint to strengthen the electric system, improve reliability and reduce the impact and duration of outages, as part of its Greater Houston Resiliency Initiative (GHRI).

Additionally, CenterPoint customers across Greater Houston have experienced about 33% fewer outages related to trees, branches, and other vegetation coming in contact with electrical equipment than it did in 2024 over the same time.

"Showing up for our customers is what drives our work every day. This is a significant improvement by any standard. The 45% decrease in outage minutes reflects the significant and real progress being felt by our communities across Greater Houston. Looking ahead, we remain laser-focused on building on the positive impact of our GHRI actions and achieving further resiliency and reliability improvements as we prepare for the reality of more extreme weather and more powerful storms," said Darin Carroll, Senior Vice President of CenterPoint's Electric Business.

Significant improvements in reliability across Greater Houston area
From January 1 through June 30, 2025, CenterPoint customers experienced shorter outages, including more than 20 million less outage minutes per month, and a 45% reduction in the duration of outages for individual customers. In addition, outages year-to-date have decreased by 41 million minutes compared to the five-year average since 2020.

Since launching the GHRI in July 2024 with a goal of improving the reliability and resiliency of the electric system, CenterPoint has completed a series of critical actions and improvements, including:

• Installing 32,000+ stronger, storm-resilient poles built to withstand extreme winds;
• Clearing higher-risk vegetation near 7,000+ miles of power lines;
• Installing 5,150+ automation devices capable of self-healing; and
• Undergrounding 400+ miles of power lines.

Working towards our goal: Building the most resilient coastal grid in the country
In the coming months and years, CenterPoint will continue working to strengthen the system and further improve reliability through a series of long-term investments, including the company's $3.2 billion Systemwide Resiliency Plan (SRP). The SRP is designed to dramatically improve resiliency against more extreme weather of the future; increase reliability for Houston customers, with a goal of reducing outages by nearly 1 billion minutes into 2029; and achieve our public goal of becoming the most resilient coastal grid in the country.
