1 State Estimator Redaction Task Force Progress Report to WMS/ROS 5/11/2011

2 Draft NPRR on Revised State Estimator Reports on Individual Transmission Load on Electrical Buses When NPRR 329, Security Classification Changes for Extracts/Reports was approved by the ERCOT Board, it suspended the posting of State Estimator Load Reports that revealed individual Load data. WMS believes there is value of Load data being available for Market Participants without releasing protected information. The NPRR requires ERCOT to redact station codes with less than ten Electric Service Identifiers (ESI IDs) to protect confidential information and publish the report every 5 minute on MIS.

3 WMS Decision in June Static rule set will develop a disclosure list New elements that are added to system will be redacted initially until State Estimator Task Force’s quarterly meeting Circuit breaker will be developed so MP can report concerns and ERCOT will analyze the element and determine if they need to remove it from disclosure list Decision point- timing of when the report is published (real-time, 24 hr delay, 48 hr delay) Next meeting on May 24
