What is ERCOT?

The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to 24 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 43,000 miles of transmission lines and 550 generation units.

ERCOT is a membership-based 501(c)(4) nonprofit corporation, governed by a board of directors and subject to oversight by the Public Utility Commission of Texas and the Texas Legislature. ERCOT's members include consumers, cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities (transmission and distribution providers) and municipal-owned electric utilities.

What is the PUCT?

The Public Utility Commission of Texas (PUCT) regulates and oversees the delivery of electricity to ensure the safety and reliability of your electric service. The PUCT’s mission is to protect customers, foster competition and promote high-quality infrastructure.

Why do we need new transmission lines?

New transmission lines are necessary to allow for a substantial increase in renewable energy supply in Texas as well as to strengthen the existing transmission system to serve Texas’ growing electric needs.

How will these new lines benefit me or areas outside of major cities that use more electricity?

New lines increase reliability, relieve congestion and benefit landowners outside of major cities by reducing the possibility of outages, improving emergency power response capability by transporting power to other areas, delivering emergency power and supporting the expansion of economic growth for businesses.

What are transmission facilities?

Transmission facilities consist of transmission lines, substations and other related equipment. As power plants generate energy, transmission lines transport that high-voltage electricity (345,000 volts for our system) from the generation facilities to the local distribution systems, which then disperse lower-voltage quantities to homes and businesses. Substations are intersections of transmission lines where electricity can be added and/or removed from the transmission system.

Is Cross Texas Transmission my retail electric provider?

No. Cross Texas Transmission is an electric transmission company, which means we operate and maintain some of the transmission lines that deliver bulk power to the retail electric providers, who then distribute it to consumers and businesses.
