Texas law now requires loads of 75 MW or more, mostly data centers, to pay their own interconnection costs, post financial security, and accept curtailment in grid emergencies, instead of spreading those costs across everyone's delivery rates. The commission's implementing rulebook is due by the end of 2026; the ERCOT large load queue behind it grew to roughly 400 GW, mostly AI data centers.
What it means for your bill: This applies statewide in the ERCOT region, not just Oncor territory. It does not change a bill directly; it decides whether data center grid costs land on developers or on the delivery rates everyone pays.
