M-A072325-01 Change to Available December Production Load Date for Energy Storage Resources in the Generation Interconnection and Modification (GIM) Process


NOTICE DATE: July 23, 2025 

NOTICE TYPE:  M-A072325-01 Operations

SHORT DESCRIPTION: Change to Available December Production Load Date for Energy Storage Resources in the Generation Interconnection and Modification (GIM) Process

INTENDED AUDIENCE: Interconnecting Entities (IEs), Resource Entities (REs), Qualified Scheduling Entities (QSEs), and Transmission Service Providers (TSPs)

DAYS AFFECTED: July 23, 2025 through December 10, 2025 

LONG DESCRIPTION: The Real-Time Co-optimization Plus Batteries (RTC+B) program is anticipated to go-live on December 5, 2025. In addition to making significant Market design changes, this project also transitions to a new representation of Energy Storage Resources (ESRs) in the ERCOT Network Operations Model and other real-time applications. In order to facilitate this transition and avoid conflicts in the Network Operations Model, ERCOT is making the following adjustments to the available Production Load Dates (PLDs) for new generation projects:

  • New ESRs that meet the deadlines and criteria for an initial PLD in December 2025 will receive a PLD of December 10, 2025.
  • All other types of new Resources that meet the deadlines and criteria for an initial PLD in December 2025 will receive a PLD of December 3, 2025.

ACTION REQUIRED: IEs and REs with a new GIM project seeking an initial PLD in December 2025 should continue to adhere to the deadlines and requirements defined in paragraph (4) of Section 3.10.1 of the Nodal Protocols.
