TO/TOP Matrix Subcommittee The TO/TOP Matrix Subcommittee (TTMS) ensures the TO/TOP Matrix is up to date with the current NERC Reliability Standards applicable to PJM as the transmission operator. The matrix is intended to clarify the assignment of tasks based on the unique relationship between PJM and its member transmission owners as defined in the Transmission Owners Agreement, Operating Agreement and PJM manuals. The matrix is simply a cross-reference to indicate where the assignment of various reliability tasks is documented. The TTMS reports to the Transmission Owners Agreement – Administrative Committee (TOA-AC). Meeting Attendance Per the TTMS Charter, TTMS membership and meetings are limited to PJM Transmission Owners who are signatories to the Consolidated Transmission Owners Agreement (Member TOs).
