Howard - SolsticeTransmission Line Project

The Howard-Solstice Transmission Line Project involves building approximately 370 miles of 765-kilovolt (kV) power line between AEP Texas’ Solstice Substation near Fort Stockton and CPS Energy’s Howard Substation southwest of San Antonio.

The transmission line will introduce a more efficient and reliable delivery system, creating additional opportunities for future growth in communities throughout West Texas.

Both events offer the same information. You can view detailed maps and talk with team members about the potential route links. There will be no formal presentation, so you can arrive at any time.

CPS Energy representatives will host open houses on Monday, Aug. 4, at the Silverado Event Center, 16490 I-35 South, Atascosa, from 5:30 to 7:30 p.m., and on Tuesday, Aug. 5, at the Uvalde County Fairplex Commissioners Auditorium, 215 Veterans Parkway, Uvalde, from 5:30 to 7:30 p.m.

Interested stakeholders are invited to attend the open house that is most convenient for them.

Feedback will be accepted at open houses, through the website feedback form, email, phone and mail through Sept. 3, 2025.

The Public Utility Commission of Texas (PUCT) requires AEP Texas officials to file a Certificate of Convenience and Necessity (CCN) application for review and approval of the project. Following the review of the CCN application, the PUCT determines the final line route. AEP Texas representatives plan to file a CCN application for the project in early February 2026 and expect to receive a response from the PUCT in summer 2026.

Texas House Bill 5066, passed by the Texas Legislature in 2023 and signed into law by Governor Greg Abbott, required the PUCT to direct the Electric Reliability Council of Texas (ERCOT) to develop an electric reliability plan for the Permian Basin region, which is an important energy location for the state and national economies.
