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 States.[6] ERCOT works with the Texas Reliability Entity (TRE),[7] one of six regional entities within the North American Electric Reliability Corporation (NERC) that coordinate to improve reliability of the bulk power grid.[8]
As the ISO for the region, ERCOT dispatches power on an electric grid that connects more than 46,500 miles of transmission lines and more than 610 generation units.[9] ERCOT also performs financial settlements for the competitive wholesale bulk-power market and administers retail switching for 7 million premises in competitive choice areas.[9]
According to an ERCOT report, the major sources of generating capacity in Texas are natural gas (51%), wind (24.8%), coal (13.4%), nuclear (4.9%), solar (3.8%), and hydroelectric or biomass-fired units (1.9%).[10]
ERCOT is a membership-based 501(c)(4) nonprofit corporation,[11][12] and its members include consumers, electric cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities (transmission and distribution providers), and municipally owned electric utilities.[13]
Power demand in the ERCOT region is typically highest in summer, primarily due to air conditioning use in homes and businesses. The ERCOT region's all-time record peak hour occurred on August 20, 2024, when consumer demand hit 85,931 MW.[14] A megawatt of electricity can power about 200 Texas homes during periods of peak demand.[15] By 2022, ERCOT had 2 GW of grid batteries, with another 6 GW underway.[16]
