NOTICE DATE:  March 2, 2020


SHORT DESCRIPTION: Implementation details of NPRR928


DAYS AFFECTED:  March 13, 2020 and April 3, 2020

LONG DESCRIPTION:  On March 13, 2020, Protocol language related to Nodal Protocol Revision Request (NPRR) 928, Cybersecurity Incident Notification, will be partially implemented.  NPRR928 establishes Market Participant notification responsibilities with respect to Cybersecurity Incidents. ERCOT is proposing a two-phase implementation process for NPRR928 to provide Market Participants time to submit Cybersecurity Contact information prior to the implementation of language under NPRR928 requiring Market Participants to notify ERCOT of a Cybersecurity Incident.

Phase 1 ImplementationMarch 13, 2020

On March 13, 2020, the Protocol sections listed below will be implemented to allow current Market Participants to submit Cybersecurity Contact information to ERCOT through the Notice of Change of Information (NCI) form (Protocol Section 23 Form E), and prospective Market Participants to designate a Cybersecurity Contact in the application process (Protocol Section 23 Forms A, B, G, I, J & M). In Phase 1, ERCOT will also be unboxing the Notice of Cybersecurity Incident form (Protocol Section 23 Form O) to allow Market Participants to voluntarily utilize the form, if necessary, prior to implementation of the remainder of NPRR928 in Phase 2.

  • Paragraph (1) of Section 16.19, Cybersecurity Incident Notification

Phase 2 Implementation: April 3, 2020

On April 3, 2020, the remaining Protocol language related to NPRR928 will be implemented.

ACTION REQUIRED:  Prior to April 3, 2020, Market Participants should designate a Cybersecurity Contact for communications with ERCOT with respect to Cybersecurity Incidents, using the Notice of Change of Information (NCI) form in Protocol Section 23 Form E.

ADDITIONAL INFORMATION:  Implementation details of NPRR928 will be further discussed at the 3/25/20 TAC meeting.
