NOTICE DATE: February 10, 2021
NOTICE TYPE: M-A021021-01 General
SHORT DESCRIPTION: Informational details related to NPRR 902 - ERCOT Critical Energy Infrastructure Information
INTENDED AUDIENCE: User Security Administrators (USAs) and Digital Certificate Holders
DAYS AFFECTED: April 1, 2021
LONG DESCRIPTION: As part of 2021 Release 1, on February 2-4, 2021, ERCOT partially implemented Nodal Protocol Revision Request (NPRR) 902, ERCOT Critical Energy Infrastructure Information. This partial implementation created a new role required for holders of Digital Certificates (Certificate Holders) to access ERCOT Critical Energy Infrastructure Information (ECEII) posted to the Market Information System (MIS) Secure or Certified Area. It is anticipated that the remaining aspects of NPRR902 will be implemented and the associated Protocol language will become effective during 2021 Release 2 (March 30 - April 1, 2021). Following this next phase of implementation, Certificate Holders will no longer have access to ECEII posted to the MIS Secure or Certified Area without Digital Certificates with the new ECEII role.
In order to ensure continued access to ECEII for Certificate Holders that need this information, USAs should assign the ICE_M_VIEW_ECEII role to their Digital Certificates prior to April 1, 2021. MPIM role installation details can be found in the attached document.
ERCOT continues to evaluate information currently posted on the MIS Secure and Certified Areas, and has identified the following categories of information as ECEII (preliminary list subject to change):
Network Operations Model and other data sets
Black Start documents
Geomagnetic Disturbance (GMD) documents
Generic Transmission Limits (GTLs)/Generic Transmission Constraints (GTCs)
Real-Time Congestion Reports (Chronic or Severe Constraints)
Generation Interconnection or Change Request (GINR)-related Information
Dynamic Data information
ERCOT System Stability Screening Studies
Remedial Action Scheme (RAS) information
Resource Asset Registration Form (RARF) Generator Data
Detailed Transmission System maps
As a reminder, upon implementation of NPRR902, Protocol Section 1.3.2 will require that a Receiving Party or Creating Party of ECEII adopt procedures to ensure that their organization’s internal distribution of ECEII is reasonably restricted to appropriate individuals.
ADDITIONAL INFORMATION: ERCOT will host a workshop on February 25, 2021 from 1:00 PM - 3:00 PM CST to discuss the implementation of NPRR902, including USAs’ assignment of the ECEII role to Digital Certificates. The workshop will be held as a WebEx and is listed on the ERCOT 2021 Meeting Calendar.
