Aggregate large-load requests in North Texas exceed announced capacity additions

The gap between requested and deliverable load is the cleanest available proxy for siting difficulty in the market.

• Oncor is the operative counterparty; ERCOT governs the deliverability question.
• Signal class: Large Energy Users. Severity assessed HIGH on the internal impact scale.
• Geography: Texas. Adjacent positions in the same corridor inherit the same constraint profile.
• Source of record: ERCOT large load interconnection · public.

• Deliverability assumptions built before this development should be re-run; corridor economics move faster than published study timelines.
• Cost exposure concentrates on positions that remain in the process — withdrawal and restudy activity reallocates rather than removes obligation.
• Contract structure (term, minimum take, collateral) is now a larger determinant of total cost of power than the headline tariff rate.
• Timing optionality has value: the interval between filing and order is where outcomes are actually influenced.

• Re-baseline the affected site or portfolio against current upgrade scope and schedule, not the last study cycle.
• Establish a monitoring position on the governing docket or queue cluster with explicit decision triggers.
• Model total cost of power on the rider and escalation trajectory across the full contract term.
• Confirm the injection point versus point of delivery before relying on any adjacency or matched-supply narrative.
