Step 6: Protect the power grid from extreme weather
In recent years, Texas has seen an increase in severe weather events, making the need for a more resilient electrical grid critical. The National Centers for Environmental Information reports that Texas has experienced 179 extreme weather events between 1980 and June 2024, including hurricanes and winter storms. These events, along with a growing reliance on electricity for homes, businesses and essential services, highlight the importance of strengthening our energy infrastructure. Entergy Texas is responding to these challenges with its Texas Future Ready Resiliency Plan, a comprehensive initiative designed to protect the power grid in Southeast Texas and ensure reliable service for our customers.
In June of 2024, Entergy Texas recently filed an application with the Public Utility Commission of Texas to approve Phase I of the Resiliency Plan. Once approved, these targeted investments are expected to save approximately $129 million in storm restoration costs and reduce power outage durations by 4.5 billion minutes over the next 50 years. By accelerating key grid hardening measures, the plan aims to minimize the impact of severe weather while managing the financial impact on our customers.
Phase I of the Resiliency Plan is a multiyear proposal that focuses on six key measures to improve the durability of our power grid.
- Distribution feeder hardening: Rebuilding main feeder lines to a storm-resilient overhead design standard.
- Lateral hardening: Rebuilding neighborhood distribution lines to a storm-resilient overhead design.
- Transmission rebuild: Replacing poles with higher wind-rated structures and equipment on high-voltage lines.
- Lateral undergrounding: Undergrounding select overhead neighborhood lines.
- Substation control house remediation: Hardening substations by upgrading roofs to meet wind standards.
- Targeted vegetation management: Proactive inspections and trimming to mitigate vegetation-related outages and wildfire risks.
The accelerated hardening projects included in Phase I total a $335 million investment in the Southeast Texas power grid. To minimize the impact on customer bills, Entergy Texas plans to secure $198 million in state grants from the Texas Energy Fund. We are also seeking federal funding through the Department of Energy’s Grid Innovation and Resilience Partnerships program, which will support $107 million in projects, including hardening the grid in Port Arthur. Entergy Texas remains committed to finding innovative solutions to reduce storm-related risks and costs for our coastal communities, including exploring alternative financing options like storm securitization to save customers money over time.
For more than two decades, Entergy Texas has made strategic investments to enhance the resilience of our power grid. Between 2013 and 2023, we replaced 271 wood poles across 71 transmission lines in the Entergy Texas service area, improving the structural integrity of our network. Additionally, we undertook significant upgrades to enhance the reliability of transmission substations along the Bolivar Peninsula. One aspect of the $110 million Bolivar Peninsula Reliability Project has already proven to be a tremendous success: composite poles. An alternative to wooden poles, composite poles are highly resilient when faced with adverse conditions, including severe storms, ice and wildfires. When Hurricane Beryl impacted the Bolivar Peninsula in July 2024, 16 wooden poles were taken out of service. Despite approximately 90 mph winds in the area, several miles of composite poles stood tall, further proving the importance of grid-hardening investments.
As the need for resiliency grows, our comprehensive Resiliency Plan will ensure that the Southeast Texas power grid remains strong and prepared for the challenges ahead.
Entergy Texas’ Palms substation on the Bolivar Peninsula is specifically designed to the latest storm resiliency standards and raised on platforms to better withstand potential storm surge.
