NOTICE TYPE: M-B062326-01 General
SHORT DESCRIPTION: Implementation of the Batch Zero Process (PGRR145/NPRR1325)
INTENDED AUDIENCE: All Market Participants
DAYS AFFECTED: July 11, 2026
LONG DESCRIPTION: ERCOT is providing notice that the Public Utility Commission of Texas (PUCT) approved the revision requests necessary to implement the Batch Zero Process, PGRR145, Batch Zero Process for Large Load Interconnections and NPRR1325, Related to PGRR145, Batch Zero Process for Large Load Interconnections, with an effective date of July 11, 2026. The current Large Load Interconnection Study process in Planning Guide Section 9 is in effect through end of day on July 10, 2026.
The Batch Zero Process is a transitional interconnection study process ERCOT will use to evaluate, on a system-wide basis, the reliability impacts of Large Load interconnection requests that meet certain study maturity and commitment criteria. Batch Zero is necessary as ERCOT intends to transition the Large Load interconnection process from an individual study-based approach to a batch study-based approach that allocates available transmission capacity for studied and committed Large Loads and, to the extent feasible, results in an actionable transmission plan.
ERCOT posted on the Large Load Integration page forms the Interconnecting Large Load Entities and Interconnecting Distribution and Transmission Service Providers must use as part of the Batch Zero Process. ERCOT is posting additional materials to assist stakeholders in preparing for the Batch Zero Process.
ERCOT recommends that affected stakeholders attend the on-going Batch Zero Market Readiness Weekly WebEx meetings with the final three provided below:
ERCOT will provide the standard 10-day Market Rules notice prior to the July 11, 2026 effective date.
ACTION REQUIRED: None
ADDITIONAL INFORMATION: ERCOT has posted the necessary guides, forms, and attestations to the Large Load Integration page and stakeholder questions can be sent to LLWG_Feedback@ercot.com.
