The Public Utility Commission of Texas approved the approximate 156 mile 345-kV transmission lines that connect ETT's Lobo Substation near Laredo, Texas with the North Edinburg Substation in the Rio Grande Valley. The completion of the project is anticipated in the Summer of 2016.
The need for transmission improvements was reinforced during the February rolling outages throughout the state. On the morning of Feb. 2, ERCOT called for firm load to be shed across the grid. The AEP Texas share of the load shed was 380 MW. After the resumption of normal activities, the Valley continued to face the possibility of outages due to severe weather. On the evening of Feb. 3, AEP Texas shed 300 MW of load in the Valley as a result of the loss of a generator and transmission import limitations.
Construction of the line also should further improve transmission reliability in the Laredo area.
ETT acquires, constructs, owns and operates transmission facilities within the ERCOT, primarily in and around the AEP Texas Central Company and AEP Texas North Company service territories.
