Transmission lines carry high voltage electricity from generation facilities to your local substation. They’re different from the distribution lines (on wooden or metal poles) that carry power from your local substation to your home.
Most of the transmission lines in and around our service area are operated by the Lower Colorado River Authority (LCRA). PEC owns and maintains only 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.
