State Estimator Redaction Task Force

This report summarizes the progress of the State Estimator Redaction Task Force as it prepares comments for NPRR 327. The group met twice since the last WMS meeting to finalize its comments and develop a methodology for redacting confidential data from generation resources and load stations. The proposed protocol aligns with PUCT rules, allowing access to real-time data while ensuring confidentiality. Key decisions include posting a redacted version of State Estimator data at intervals, and the withdrawal of NPRR 373 in favor of the comments submitted for NPRR 327.
