NOTICE DATE: June 30, 2026
NOTICE TYPE: M-B063026-01 PGRR
SHORT DESCRIPTION: Partial Implementation Details of PGRR145/NPRR1325, Batch Zero Process for Large Load Interconnections
INTENDED AUDIENCE: All Market Participants
DAYS AFFECTED: July 11, 2026
LONG DESCRIPTION: On July 11, 2026, Planning Guide language associated with Planning Guide Revision Request (PGRR) 145, Batch Zero Process for Large Load Interconnections, and Protocol language associated with Nodal Protocol Revision Request (NPRR) 1325, Related to PGRR145, Batch Zero Process for Large Load Interconnections, will be partially implemented.
PGRR145 and the related NPRR1325 implement the Batch Zero Process.
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 (ILLEs) and Interconnecting Distribution Service Providers (DSPs) and Transmission Service Providers (TSPs) must use as part of the Batch Zero Process. ERCOT is posting additional materials to assist stakeholders in preparing for the Batch Zero Process.
Specifically, all Protocol and Planning Guide language, with the exception of the following sections, will be implemented:
- Protocol Section 4.4.9.4, Mitigated Offer Cap, Mitigated Offer Floor, and Adjusted Bid Caps
- Protocol Section 4.4.9.4.4, Adjusted Bid Caps
- Paragraph (1) of Protocol Section 6.5.7.3, Security Constrained Economic Dispatch
- Paragraph (14)(b)(iv) of Protocol Section 6.5.7.3
- Protocol Section 6.5.7.11, Provisional Controllable Load Resource (PCLR) Ramp Rate Requirements
- Paragraphs (2) and (3) of Planning Guide Section 9.6.1, Additional Energization and Operation Requirements for Provisional Controllable Load Resources (PCLRs)
The remaining unimplemented portions of PGRR145 and NPRR1325 will be implemented at a later date.
ADDITIONAL INFORMATION: In accordance with Protocol Section 21.6, Nodal Protocol Revision Implementation, and Planning Guide Section 1.2.5, Planning Guide Revision Implementation, ERCOT provides notice as soon as practicable but no later than ten days prior to implementation.
PGRR145, NPRR1325, and associated documents can be found on the ERCOT website.
