System Changes

If a Market Participant wishes to request ERCOT to change its computer systems, and this change does not require a revision to the Protocols, the Market Participant may submit a System Change Request (SCR).

Each SCR is considered by the Protocol Revision Subcommittee (PRS), Technical Advisory Committee (TAC) and the ERCOT Board.  If so recommended by TAC, the system change will be considered for project prioritization by TAC and ERCOT.

SCRs, both pending and completed (approved, rejected and withdrawn) are available for viewing in this section.

Templates for SCRs and other related forms are listed below.  For guidelines on submitting revision requests or comments, please refer to the Revision Request and Comment Submission Guidelines.  Completed forms should be submitted to
