Texas Pauses Data Center Interconnection Amid 474 GW Queue at ERCOT

Texas Governor Greg Abbott ordered an audit on August 3 of all data centers in ERCOT's interconnection queue, which totals approximately 474 GW in requests, more than five times Texas's peak demand record. ERCOT responded by delaying its "Batch Zero" transmission study.

In his letter to the grid operator and state regulators, Abbott noted that approximately 90% of new energy requests come from data centers and described that scale as a risk to grid reliability and stability, according to Utility Dive. The audit will examine whether projects generate their own electricity, recycle water, and finance their own infrastructure. ERCOT published a preliminary forecast in May projecting peak demand more than four times higher by 2032, driven by data centers and large consumers. For the region, the decision signals how ERCOT, the reference grid for the energy bridge between the Gulf Basin and Latin America, will ration its transmission capacity in the face of artificial intelligence demand.

ERCOT has delayed the "Batch Zero" process, which covers the first batch of projects under the new large-load interconnection process, and plans to request a good-cause exemption from the Public Utility Commission of Texas (PUCT) at its open meeting on August 20. The large-load queue reached approximately 226 GW in November, nearly four times the 63 GW recorded at end-2024, and 77% of that demand comes from data centers seeking to connect by 2030, according to Latitude Media. The 474 GW figure represents requests, not built capacity: between 2024 and 2025 ERCOT added approximately 23 GW of new generation. Abbott signed legislation in July directing the PUCT to establish transparency rules for large consumers, with a deadline of December 2026.

On August 20, the PUCT will assess ERCOT's request for an exemption from the "Batch Zero" process timeline, the first concrete signal of the suspension's scope. Law firms advising developers, including Troutman Pepper Locke, have noted that projects will need to reassess timelines and financing terms in light of the suspension.
