ERCOT Load Growth, Data Centres and the Texas Reliability Problem Set

The Electric Reliability Council of Texas operates a grid that is largely separate from the Eastern and Western interconnections. That architecture concentrates both the costs and benefits of Texas choices inside Texas. Rapid large-load growth, especially from data centres and industrial projects, collides with interconnection timelines, gas deliverability in extreme weather, and the politics of retail prices. Adequacy in a heat wave or freeze depends on accredited resources, fuel, and transmission between zones. National reforms under Order No. 2023 address generator interconnection processes under FERC's jurisdiction; ERCOT's governance differs, but the physics of queues, transformers and line siting do not.

Large loads that expect energisation on software-industry timelines will meet steel-industry lead times. Nationally, EIA planned 12.3 gigawatts of 2025 retirements with major coal exits, while earlier 2024 plans had shown a temporary slowdown. Serious planning publishes large-load queues, aligns ancillary service needs with inverter-based penetration, stress-tests gas deliverability, and tells corporate customers truthful energisation dates.
