Transmission Projects
Transmission lines carry high voltage electricity from generation facilities to your local substation. From there, smaller distribution lines carry power to your home.
PEC owns and maintains about 304 miles of transmission line. As our Hill Country community continues to grow, our system grows, too.
Maintaining and improving our transmission equipment is a mainstay of our commitment to delivering low-cost, reliable, and safe energy solutions.
Current transmission projects:
PEC is upgrading approximately 4 miles of the existing transmission line between the Cedar Valley substation and Friendship substation in Travis and Hays County. This project will help meet the area’s growing demand for electric power, improve system reliability and reduce ongoing maintenance costs.
Construction is in progress and scheduled to complete in December 2025.
PEC will be upgrading the Nameless substation. As a part of this project, PEC will install temporary structures and install a new structure outside of the Nameless substation.
Construction of the temporary structures is scheduled to begin in August 2025 and be completed in December 2025. Construction of the final configuration is scheduled to begin in March 2026 and be completed in May 2026.
PEC is upgrading approximately 11 miles of the existing transmission line between the Blanco substation and Devils Hill substation in Blanco and Comal counties. The purpose of this project is to improve the reliability and capacity of the line.
Construction is scheduled to begin in January 2026 and be completed in September 2026.
PEC will construct the transmission line cut-in for the Old 81 substation. The purpose of this project is to connect the existing transmission line to PEC’s new substation.
Construction is scheduled to begin in April 2026 and continue through May 2026.
PEC is upgrading approximately 4.5 miles of the existing transmission line between the Friendship substation and Rutherford substation in Hays County. This project will help meet the area’s growing demand for electrical power, improve system reliability, and reduce current ongoing maintenance costs.
Transmission line upgrade construction is estimated to begin in July 2026 and is expected to be completed by March 2027. Construction activities will include preparing the site for heavy equipment such as bucket trucks and cranes, as well as digging holes, setting and removing poles, and installing new wire. Upgrades will take place within existing PEC easement areas. Due to our updated design, the new poles/structures will be placed in adjusted locations within the easement.
