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 system, but 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.
