As hurricane season descends upon the region, CenterPoint Energy has shared the latest update on its Greater Houston Resiliency Initiative (GHRI) that’s been working to make grid upgrades and introduce weather-related tech since 2024.

As of April 2026, CenterPoint had:

  • Replaced more than 65,000 poles with stronger storm-resistant infrastructure
  • Trimmed or cleared more than 10,000 miles of vegetation
  • Undergrounded more than 500 miles of power lines
  • Installed more than 600 automation devices
  • Installed more than 150 weather stations

In May, CenterPoint announced its new Community Progress Tracker, which helps residents track electronic infrastructure improvements. In terms of other technology, CenterPoint has announced its partnership with weather, wildfire and flood modeling software Technosylva. The software is expected to help CenterPoint track weather conditions in advance to better prepare crews.

CenterPoint has also added 150 weather stations to improve weather monitoring, conducted a full-scale hurricane response exercise involving more than 400 employees and completed more than 25,000 hours of FEMA training across more than 800 employees. The company opened a new year-round Emergency Operations Center to help coordinate with emergency response partners, local and state officials, and media during major weather events.

“We are proud of the progress made in 2025, which helped deliver more than 100 million fewer outage minutes when compared to 2024, and we are determined to make even more progress in 2026 as we work toward our defining goal: building the nation's most resilient coastal grid,” Nathan Brownell, CenterPoint's vice president of resilience and capital delivery, previously said in a news release.

According to the company, the GHRI aims to improve overall grid resiliency and reliability and to reduce outages for customers. CenterPoint projects its efforts can reduce customer outages by 150 million by the end of 2026.
