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.
