Sharyland Utilities believes energy infrastructure is critical to ensuring the continued economic development and prosperity that Texas currently enjoys. We also believe that creativity and innovation will be required to meet Texas' electric needs in the 21st century. Sharyland will continue to be on the cutting edge of efficiently moving transmission projects from the conceptual phase to operational assets that provide necessary infrastructure for our thriving Texas economy.

    Lower Rio Grande Valley Upgrade Projects

    On September 23, 2021, the Public Utility Commission of Texas (PUCT) ordered work to begin immediately on two new transmission projects in the Lower Rio Grande Valley (LRGV), both interconnecting with Sharyland's existing assets, that will provide additional load serving capability and resiliency to the region's transmission grid.

    These two projects will provide critical and timely upgrades that will ease constraints and improve the resiliency of ERCOT transmission system in South Texas.

    Proposed 345-kV La Palma to Kingfisher Transmission Line Project

    This proposed project will close a critical loop in the regional transmission system by having Sharyland build the new Kingfisher substation along its existing 345 kilovolt (kV) transmission line located near San Benito, Texas, and also building a portion of a new 345-kV transmission line to connect its new substation to the existing La Palma substation owned and operated by AEP Texas. This project will be completed by mid-2026.

    Sharyland and AEP Texas are working in close cooperation to keep the public informed on the progress of this project and to gather input from key stakeholders, such as potentially affected landowners and public officials.

    Second Circuit Upgrade of Existing 345-kV Transmission Facilities

    This project will add a second circuit to an existing 345 kilovolt (kV) transmission line that runs from San Antonio down to Laredo, and then down to McAllen and Brownsville. The southeasternmost segment of this project includes Sharyland's portion of the Cross Valley Transmission Project located entirely within Cameron County, which Sharyland completed and placed into service in 2016. Sharyland's portion of the new second circuit will be completed by mid-2024.
