The Rio Hondo - Wren Transmission Line Project involves building approximately 6 miles of two new single-circuit 345 kilovolt transmission lines, constructing a new Substation and upgrading the existing Rio Hondo Substation.
The project provides additional electrical capacity to support the area's future growth and development.
