Electricity transmission to the Rio Grande Valley could be significantly improved as part of a major upgrade project that’s been ordered to move forward by the Texas Public Utilities Commission.
The Lower Rio Grande Valley System Enhancement Project would add a 345-kilovolt transmission line and three substations, with the goal of improving the reliability of electricity service and to meet future demand.
The new transmission line would run within existing easements along the Rio Grande. The estimated $1.25 billion project was put together by the ERCOT regional planning group, and it involves AEP Texas, South Texas Electric Cooperative, and Sharyland Utilities. The long-term project wouldn’t be completed until 2027.
