As of February 4, 2025, CenterPoint Energy filed a $5.75 billion system resiliency plan with the Public Utility Commission of Texas that calls for installing automation devices on power lines serving large numbers of customers, undergrounding more than 50% of its electric system, strengthening 130,000 power poles, raising substations above flood plains, and expanding vegetation management. [1] CenterPoint stated that the proposal is the largest single grid resiliency investment in the company’s history. CenterPoint said the plan builds on its Greater Houston Resiliency Initiative that launched after Hurricane Beryl left almost 2.3 million customers in Houston without power in August 2024. In its application, the company noted that it serves a quarter of the load on the Electric Reliability Council of Texas system, and its critical customers include the Port of Houston, Texas Medical Center, two airports, and several chemical refineries. CenterPoint’s resiliency plan calls for rebuilding or upgrading more than 2,200 transmission structures, utilizing a three-year vegetation management cycle for transmission and distribution lines, and modernizing 34,500 spans of underground cables. The utility will also improve its existing technology systems and move customer-facing websites from on-premise to cloud-based hosting for better communications.
