Filings submitted to the Public Utility Commission of Texas
As part of Entergy Texas’ Southeast Texas Energy Plan, numerous filings will be submitted to the Public Utility Commission of Texas to support the everyday energy needs of our growing communities. Below is a list of the STEP Ahead filings:
| STEP Ahead component | Description of filing | Date filed | Expected PUCT decision date |
| Texas Future Ready Resiliency Plan | To better protect the Southeast Texas power grid from extreme weather and improve service reliability, Entergy Texas filed an application with the PUCT for approval of Phase I of its Texas Future Ready Resiliency Plan. These targeted investments are expected to save customers millions in storm restoration costs and reduce power outage durations by one billion minutes over the next 50 years. | June 2024 | Approved in January 2025 |
| Dispatchable Portfolio | Entergy Texas filed an application with the PUCT to seek approval of two state-of-the-art natural gas power plants to be named Legend and Lone Star. The proposed 24/7 dispatchable power generation resources will provide more than 1,200 megawatts of additional generation to the Entergy Texas service area and bring a total of $2.8 billion in economic benefits to the region. Together, these projects are known as the company’s Dispatchable Portfolio. | June 2024 | Approved in September 2025 |
| SETEX Area Reliability Project |
Entergy Texas filed an application with the PUCT to construct, own, and operate a new single-circuit 500-kilovolt transmission line, approximately 131 to 160 miles in length (depending on the route ultimately approved by the PUCT), in Jasper, Montgomery, Newton, Polk, San Jacinto, Trinity, Tyler and Walker counties. The new transmission line will connect the proposed Babel 500-kV Switching Station to the proposed Running Bear Substation. This project is required to meet federal reliability standards, and will increase operational flexibility, help meet the growing power demands of Southeast Texas, and increase reliability and resiliency during extreme events. | February 2025 | October 2025 |
| Legend to Sandling | Entergy Texas filed an application with the PUCT to construct, own, and operate a new single-circuit 230 kilovolt transmission line approximately 8.8 to 9.9 miles in length (depending on the route ultimately approved by the PUCT) in Jefferson County. The line will connect the existing Legend Substation to the currently under-construction Sandling Substation. This project will help meet the growing power demands of Southeast Texas and maintain compliance with federal reliability standards. | April 2025 | Approved in September 2025 |
| Cypress to Legend | Entergy Texas filed an application with the PUCT to construct, own, and operate a new single-circuit 500 kilovolt transmission line approximately 40 to 49 miles in length (depending on the route ultimately approved by the PUCT) in Hardin and Jefferson counties. The new transmission line will be routed from the existing Entergy Texas Cypress Substation in Hardin County and extend to the new Legend 500 kV Substation in Jefferson County. | May 2025 | December 2025 |
| Southline to Jacinto | Entergy Texas filed an application with the PUCT to construct, own, and operate a new 138-kilovolt transmission line approximately 6 to 10 miles (depending on the route ultimately approved by the PUCT) in Liberty and San Jacinto counties. If approved, the project will prevent contingent low-voltage and thermal overloads as well as benefit load-serving capability driven by commercial and residential growth in the area. The proposed transmission line would follow a yet-to-be- selected corridor from the existing Southline Substation to the existing Jacinto Substation. | September 2025 | March 2026 |
