The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to more than 25 million Texas customers -- representing about 90 percent of the state’s electric load. As the independent system operator for the region, ERCOT schedules power on an electric grid that connects more than 46,500 miles of transmission lines and 600+ generation units.

Since its inception in 2009, Lone Star has focused on delivering industry leading transmission services in ERCOT to both Texans and organizations connected to the Lone Star system.

Lone Star is a Transmission Service Provider (TSP), which means we operate and maintain transmission lines that deliver bulk power to other utilities that in turn distribute the power directly to consumers and businesses through the lower voltage distribution system. Transmission / Distribution Service Provider (TDSPs) own / operate, for compensation, the equipment / facilities to transmit and/or distribute electricity in Texas. TDSPs are regulated by the Public Utility Commission of Texas (PUCT) and are required to provide non-discriminatory access to the grid for generation and/or load requests.
