ERCOT Revision Requests for Improved Market Information Accessibility
In response to assessments identifying the absence of Critical Energy Infrastructure Information (ECEII), ERCOT has initiated a series of Revision Requests to relocate reports from the MIS Secure Area to the ERCOT website. These requests aim to enhance public access to market information and remove non-ECEII from restricted areas, aligning with a policy of transparency and security. The timeline illustrates the progression of these efforts, culminating in the proposed revisions detailed in the tables appended to the ERCOT Public documents.

Revision Requests Overview Following SME assessments that reports do not contain ERCOT Critical Energy Infrastructure Information (ECEII), batch of 5 Revision Requests to revise market rules that require reports to be posted in the Market Information System Secure Area (MIS Secure) to instead require publishing the reports on the ERCOT website: Improve public access to market information As a matter of policy, non-ECEII should be in the public domain 2 ERCOT Public
Revision Requests Timeline 12/21/16 6/1/21 10/23/23 2024 PUCT approved NPRR 1183 NPRR 1183 to move from the MIS Secure Area to the ERCOT website information assessed to not contain ECEII, including projected Ancillary Service Requirements and Resource forecast criteria Nodal Protocol Revision Request 902 (NPRR 902) defines ECEII and ECEII responsibilities; ERCOT communicated a next phase to further assess reports in the MIS Secure Area Planning Guide Revision Request 036 (PGRR 036) moves Critical Energy Infrastructure Information (CEII) to the MIS Secure Area ERCOT submits 5 Revision Requests to move remaining reports without ECEII from the MIS Secure Area to the ERCOT website NPRR 902 PGRR 036 ERCOT Public
Publishing Information Prepared for a Market-Audience Reports to move from MIS Secure to ERCOT website were assessed to not contain Protected Information: Assessed to not contain Confidential ECEII foreseeably useful to planning an attack on ERCOT System Infrastructure Do not contain Confidential information for an individual Market Participant ERCOT Public
