Electric Reliability Council of Texas (ERCOT)
Electric Reliability Council of Texas (ERCOT; Austin TX; non-profit ISO; not FERC-regulated; manages ~90% of Texas electric load) is the operator of the Texas Interconnection — a deliberately isolated power grid that operates independently of the Eastern and Western US grids to avoid federal FERC regulation. ERCOT manages ~85 GW of generation serving ~26 million customers in Texas. The isolation from neighboring grids is the defining structural feature: Texas cannot import or export electricity during grid emergencies because the DC tie lines to Eastern and Western interconnections have negligible capacity relative to Texas load. Industrial electricity consumers in Texas include refineries and petrochemical plants along the Gulf Coast (Houston Ship Channel), aluminum smelters, steel mills, and the fastest-growing data center and cryptocurrency mining sectors in the US. Texas has historically offered among the lowest industrial electricity prices in the US (~$40-60/MWh) due to abundant wind generation and deregulated market structure — until Winter Storm Uri proved the isolation premium can be catastrophic.

ERCOT control area: ~85 GW managed generation capacity; ~90% of Texas electric load; DC-isolated from Eastern/Western interconnections. Deliberately isolated from FERC jurisdiction since 1935 Federal Power Act. Isolation means no import capacity during emergencies. Source: https://www.ercot.com/gridinfo/resource
ERCOT — Texas Interconnection Grid (Houston Hub) →
USTexas
The ERCOT grid (Houston pricing hub) is the primary electricity market for Texas Gulf Coast industrial consumers — including Olin Corporation chlor-alkali plants (Freeport TX; ~900,000 t/yr chlorine capacity), Occidental Chemical (OxyChem) plants, and chemical complexes on the Houston Ship Channel. ERCOT's physical isolation from Eastern/Western Interconnections means Texas industrial consumers have no import alternative during grid emergencies. During Winter Storm Uri (February 2021), ERCOT prices reached the $9,000/MWh market cap for ~90 hours; many industrial consumers (including chemical plants) had to shut down completely. Chlor-alkali electrolysis cannot be ramped quickly — unplanned shutdowns damage electrolyzer cells and can take weeks to restart.

Did you know2021
ERCOT is tracked as a power grid operator (energy supply chain), but Texas's electrical grid uniquely hosts the largest concentration of US oil and gas production infrastructure — the same wells, pipelines, compressors, and refineries that supply the rest of the country with fossil fuels depend on ERCOT electricity to operate. During February 2021's Winter Storm Uri, ERCOT's grid failure cascaded into natural gas well and pipeline failures as wellhead equipment froze and electric-powered compressors failed — cutting gas supply to over 50% of the country's gas generation capacity simultaneously. The Texas power grid failure became a national natural gas supply chain failure: the electricity grid operator inadvertently controls the US fossil fuel supply chain's most critical production region.
FERC/NERC ↗Chokepoint2022
ERCOT's energy-only market design (no capacity market requirement, unlike PJM/MISO) was the proximate cause of the Winter Storm Uri generation collapse. Without a capacity market, generators have no financial incentive to invest in weatherization — the cost of weatherizing turbines, natural gas pipes, and instrument sensors against sub-zero temperatures is not recovered through the energy-only pricing mechanism. Texas regulators and PUCT (Public Utility Commission of Texas) were aware of the winterization deficiencies: the same failure mode — cold weather-induced generation outages — occurred during Winter Storm Elliott (December 1989), Winter Storm Lee (February 2011), and a 2011 FERC/NERC report explicitly warned Texas that its generators were not winter-ready. ERCOT's isolated grid structure precluded the standard reliability fix (interconnection with neighbors) and the market design precluded the standard capacity fix (mandatory winterization with cost recovery). Texas chose market design over reliability — twice — and suffered the largest winter power crisis in US history on the third occurrence. Post-Uri, Texas Senate Bill 3 (June 2021) mandated weatherization of generation and fuel supply infrastructure with PUCT enforcement, but implementation has been contested.

R Street Institute ↗Concentration2021
ERCOT is the single electricity source for approximately 30% of US refinery capacity, 25-30% of US petrochemical production, and a significant share of US LNG export capacity — the most energy-intensive production cluster in North America. The Gulf Coast petrochemical complex stretching from Corpus Christi to Port Arthur is powered entirely by ERCOT. There is no alternative electricity path: ERCOT's grid interconnects to the Eastern Interconnection only through ~900 MW of HVDC ties at Oklahoma and Louisiana borders — roughly enough to power a single large suburb, not the region's industrial base. Unlike California, which can import 20-25 GW of power from the Pacific Northwest during supply emergencies, or New York, which can receive power from New England, Quebec, or PJM — Texas's industrial production is electrically isolated. An extreme weather event, cyberattack, or catastrophic generation failure on ERCOT would be unmitigable by imports, affecting US gasoline and jet fuel production, ethylene and plastic production, fertilizer production, and LNG export capacity simultaneously.
Federal Energy Regulatory Commission ↗Origin2023
ERCOT (Electric Reliability Council of Texas) was established in 1970 following the 1965 Northeast blackout that affected 30 million people across the US and Canada. Texas politicians, already inclined toward regulatory independence, used the blackout as justification for creating an isolated Texas grid not subject to federal FERC jurisdiction — a deliberate policy choice to remain sovereign over Texas energy policy. ERCOT operates the only major US grid not interconnected with the Eastern or Western Interconnections, making it uniquely exposed to within-state failures with no external backstop, as demonstrated catastrophically during the February 2021 winter storm that killed 250+ people.
Electric Reliability Council of Texas ↗Incident
During Winter Storm Uri (Feb 2021), the ERCOT grid nearly collapsed and forced rolling blackouts that shut down a large share of Gulf Coast refining capacity — an estimated ~4 million barrels/day of U.S. refining went offline. Because ERCOT is islanded with little ability to import power from neighboring grids, a single weather event simultaneously knocked out electricity AND the refineries that depend on it, cascading into gasoline price spikes nationwide. The same isolated-grid design that the input depends on is its single greatest historical failure mode.
