NOTICE DATE: July 24, 2024

NOTICE TYPE: M-B072424-01 Operations

SHORT DESCRIPTION: Testing phase of submitting unit test request via NDCRC

INTENDED AUDIENCE: Qualifies Scheduling Entities (QSE), Resource Entities (RE)

DAYS AFFECTED: August 1, 2024 thru September 30, 2024

LONG DESCRIPTION: ERCOT operations requested a way to streamline the current email process when having to respond to numerous unit test requests from QSE's and RE's. A solution has been developed to use Net Dependable Capability and Reactive Capability (NDCRC). Moving to an electronic version of unit test requests will be a benefit to achieving a more efficient process by adding guard rails to the current process and establish a more efficient response. ERCOT operations plans to allow QSEs to test the NDCRC enhancements during the month of August and allow parallel operations during the month of September with the cutover to the electronic version for October 1, 2024.  Below are the QSEs testing, parallel operations, and cutover plan timelines.

• 07/25/2024 - NDCRC changes will be deployed into Production. This is a soft launch to help QSEs get familiarized with NDCRC display changes and start planning for testing.
• 08/01/2024 - 08/31/2024 - QSEs Testing window. QSEs can submit test requests into NDCRC. At the end of the testing phase, test data requests will be deleted from NDCRC system.
• 09/01/2024 - 09/30/2024 - Window of parallel Operation of current email process and new NDCRC process. QSEs are requested to submit unit test requests using either current email process or NDCRC UI. Control Room will be approving Unit test requests during this window based on whichever process is used by QSEs for parallel operation. This will alleviate the burden on QSEs having to submit requests through both current and new process.
• 10/01/2024 - Cutover to use NDCRC exclusively.

NDCRC user interface (UI) issues identified in testing and parallel operations phases will be addressed based on priority before cutover.

During testing phase, QSEs are expected to utilize respective RE digital certificates to submit the unit test.

ACTION REQUIRED: QSEs are required to participate in NDCRC testing and parallel operation during the months of August and September and be ready for cutover to NDCRC on 10/01/2024.
