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.
Cross Valley Project
Sharyland Utilities and Electric Transmission Texas (ETT) jointly developed a 345 kV transmission line in the Lower Rio Grande Valley of Texas as part of a larger effort known as the Cross Valley Project, which was needed in order to ensure reliable electric service for the Lower Rio Grande Valley, while also addressing continued growth in electrical load in the Brownsville area. The new transmission line crossed the southern portions of both Hidalgo and Cameron counties and was placed into service in June 2016.
DC Tie Between Texas and Mexico
Commissioned into service in October 2007 and expanded in 2014, the Sharyland DC Tie is a 300 MW High Voltage Direct Current Transmission Interconnection located along the Rio Grande border connecting at a point near the cities of Mission, Texas, and Reynosa, Tamaulipas. This DC Tie links the Electric Reliability Council of Texas (ERCOT) grid with the Mexican national grid, operated by the Centro Nacional de Control de EnergÍa (CENACE), allowing for cross-border open access to support commercial business activity and to provide emergency power with Texas and Mexico. Its technology allows for bi–directional flow of electricity between both grids, thereby allowing each grid to rely on the other in times of peak demand. Not only does this strengthen the stability of both grids, it also fosters the international wholesale market of electricity.
