The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power on the Texas Interconnection that supplies power to 26 million Texas customers – representing 90 percent of the state's electric load. [3] ERCOT is the first independent system operator (ISO) in the United States [4] and one of nine ISOs in North America. [5]
The Texas Interconnection covers most of the state of Texas. Interconnections can be tied to each other via high-voltage direct current power transmission lines ( DC ties ), or with variable-frequency transformers (VFTs), which permit a controlled flow of energy while also functionally isolating the independent AC frequencies of each side.
The Electric Reliability Council of Texas, Inc. (ERCOT) is an American organization that operates Texas's electrical grid, the Texas Interconnection, [3] [4] which supplies power to more than 25 million Texas customers and represents 90 percent of the state's electric load. [5] ERCOT is the first independent system operator (ISO) in the United ...
The Texas Interconnection covers most of the state of Texas. It is tied to the Eastern Interconnection at two points, and also has ties to non-NERC systems in Mexico. The Quebec Interconnection covers the province of Quebec and is tied to the Eastern Interconnection. About one third of Canada's installed power (42 GW out of 130) and about one ...
Across large regions, they schedule the use of transmission lines; manage the interconnection of new generation and monitor the markets to ensure fairness and neutrality for all participants. Providing these services regionally is more efficient than providing them on a smaller-scale, utility by utility.
Nationwide data from the U.S. Energy Information Administration [7] shows that Texas's electric prices did rise above the national average immediately after deregulation from 2003 to 2009, but from 2010 to 2015, prices dropped significantly below the national average price, with a total cost of $0.0863 per kWh in Texas in 2015 vs. $0.1042 ...
The Tres Amigas SuperStation (lit. ' Three Friends SuperStation ') was a project proposed in 2009 to unite North America’s two major power grids (the Eastern Interconnection and the Western Interconnection) and one of its three minor grids (the Texas Interconnection), with the goals of enabling faster adoption of renewable energy and increasing the reliability of the U.S. grid.

For example, compare the wide area synchronous grid map of Europe (in the introduction) with the map of HVDC lines (here to the right). Solid state transformers have larger losses than conventional transformers, but DC lines lack reactive impedance and overall HVDC lines have lower losses sending power over long distances within a synchronous ...
