Harlandale to Sommers Transmission Line Rebuild



As part of our commitment to deliver reliable service, we routinely evaluate our system and perform needed maintenance or updates.

This project involves rebuilding a segment of an existing double circuit 138 kV transmission (power) line between our Harlandale and Sommers Substations. All structures along this route, including towers, electric cables and foundations will replaced.

Maintaining our customers’ need for reliable electric power is of utmost importance. Once complete, this work will improve the quality and safety of an aging transmission line and help ensure electric reliability between the two substations.
