ERCOT
The Electric Reliability Council of Texas, an independent system operator managing approximately 90% of Texas's electric load and serving around 26 million customers. It operates outside direct Federal Energy Regulatory Commission jurisdiction and runs a fully competitive real-time wholesale electricity pricing mechanism.
Core Facts
Timeline (last 90 days)
ERCOT covers about 90% of Texas's electricity load and has almost no large-scale synchronous interconnection with the two major grids, the Eastern and Western Interconnections, so it is often called an "island grid."
ERCOT is largely exempt from federal jurisdiction over interstate transmission under the Federal Power Act, allowing it to design its own market rules, and it is one of the grids in the United States with the highest proportion of renewable energy integration.
ERCOT is an independent system operator managing approximately 90% of Texas's electrical load, covering roughly 26 million customers.
The Texas power grid does not interconnect across state lines, and therefore is not subject to direct jurisdiction by the Federal Energy Regulatory Commission (FERC).
During Winter Storm Uri in 2021, ERCOT narrowly avoided a complete collapse, leaving approximately 4.5 million households without power for several days.
Winter Storm Uri in February 2021 caused power outages for more than 4.5 million households in Texas, resulting in over 200 deaths and estimated economic losses of $195 billion.
Regional electricity markets in the United States such as PJM and ERCOT use a Locational Marginal Pricing (LMP) mechanism, where prices can fluctuate from a few cents to hundreds of dollars or even turn negative.
ERCOT wholesale electricity prices frequently go negative during periods of abundant wind power, indirectly reflecting the ample supply of low-carbon electricity.

Approximately 70% of the transmission lines and transformers in the U.S. power grid have been in service for more than 25 years, and the grid consists of three major interconnections: the Eastern Interconnection, the Western Interconnection, and the Texas Interconnection (ERCOT).
