NOTICE DATE: May 3, 2021


SHORT DESCRIPTION: Implementation Details of NPRR902

INTENDED AUDIENCE: All Market Participants

DAYS AFFECTED: June 1, 2021

LONG DESCRIPTION:  On June 1, 2021, Protocol language associated with Nodal Protocol Revision Request (NPRR) 902, ERCOT Critical Energy Infrastructure Information, will be implemented.

NPRR902 clarifies parties’ responsibilities regarding ERCOT Critical Energy Infrastructure Information (ECEII). More specifically, NPRR902 defines ECEII; adds lists of items that are considered ECEII; specifies the restrictions imposed upon parties that receive or create ECEII; allows Market Participants to restrict individual access to ECEII within their organizations through the use of ECEII-eligible Digital Certificates; and provides a framework for the submission of ECEII to ERCOT.  A process has been created for contesting ERCOT determinations regarding confidentiality status.

ACTION REQUIRED:  Following implementation, Certificate Holders will no longer have access to ECEII posted to the Market Information System (MIS) Secure or Certified Area without a Digital Certificate with the new ECEII role. For impacted Market Participants, in order to ensure continued access to ECEII for Certificate Holders that need this information, User Security Administrators (USAs) should assign the ICE_M_VIEW_ECEII role to their Digital Certificates prior to June 1, 2021.  Additional MPIM role installation details can be found in the document attached to Market Notice M-A021021-01 (February 10, 2021). A preliminary list of MIS Certified and Secure Area postings that have been classified as ECEII is attached to this Market Notice.

ADDITIONAL INFORMATION:  Pursuant to Nodal Protocol Section 21.6, Nodal Protocol Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.

NPRR902 and associated documents can be found on the ERCOT website.
