ERCOT’s Proposed Large Load Batch Study Process in Progress — Key for Data Centers

ERCOT is in the middle of a major redesign of how large load interconnections are studied in Texas. At a February 3, 2026 workshop, ERCOT presented a draft framework for a new Large Load “Batch Study” process, developed in connection with PUC Project No. 59142, Review of ERCOT’s Interconnection Processes for Large Loads.

This proposal, while still preliminary, signals a significant shift that will directly affect data centers, industrial customers, transmission service providers, and developers planning large load projects in ERCOT.

Why ERCOT Is Proposing a Batch Study Process

Today, large loads are generally studied one-by-one, often leading to:

• Repeated restudies as assumptions change

• Uncertainty around timing and feasibility

• A growing backlog of interconnection requests

ERCOT’s proposal would move to an ERCOT-led batch study model, grouping qualifying large loads together to improve:

• Efficiency

• Consistency of assumptions

• Transparency

• Certainty around load allocation — while maintaining system reliability

Key Elements of the Proposed Framework

Based on the workshop presentation, the proposal includes:

• Semiannual batch studies for qualifying large loads

• Screening and commitment requirements intended to filter speculative projects

• Load allocation by year, with ramping schedules tied to system constraints

• A defined Batch Zero transition process for projects already in the queue

• Use of stability screening during batch studies, with full stability analysis later to meet NERC requirements

• Clearer alignment between Batch Studies, Regional Planning Group (RPG) review, and the Regional Transmission Plan (RTP)

Importantly, the Batch Study outcome would be reserved capacity and allocated load, not a guarantee of real-time service — an important distinction for project planning and financing.

Practical Takeaway

If you have existing large load requests, are planning future ERCOT projects, or rely on interconnection timing certainty, this process will matter to you. If we can assist you, or provide assistance in considering how these changes affect a project, please get in touch.

ERCOT has described this framework as conceptual and subject to change. This article reflects the process as of February 2026.
