What will the transmission line structures look like?
LCRA TSC is considering double-circuit-capable steel lattice structures as the typical transmission structures for the 345-kV projects described above. Other structures could include lattice poles or tubular poles. Right of way, schedule, and cost considerations will be used to decide the preferred transmission structure type. Typical transmission structures supporting 345-kV lines will be about 120 feet to 180 feet above the ground. Typical span lengths for projects like this range from 700 feet to 1,500 feet (about four to six structures per mile). The PUC will ultimately approve the structure type(s) for the project.
