Status
SAC directed Staff to advise the Requestor of this SAR to solicit support from IDCWG and/or the ORS for volunteers to this drafting team.  Initial drafting team solicitations were due June 1, but there were no volunteers.

Purpose/Industry Need
This SAR is required to revise IRO-004-0 Requirement 4 to require the submission of system operational data by noon the day prior as soon as it is known to be in effect for the next day.  The Interchange Distribution Calculator Working Group (IDCWG) and the Operating Reliability Subcommittee (ORS) reviewed Section A (System Data Exchange (SDX) — Eastern Interconnection) of the Reliability Coordinator Reference Document contained in the NERC Operating Manual, and concluded that the existing reliability standards do not adequately address the requirements placed on reporting entities within the reference document.  Therefore, the IDCWG and the ORS support a revision to IRO-004-0 to require the timely submission of system operation data used by reliability coordinators, transmission operators, and balancing authorities to perform next day operational analysis.  This SAR would also modify the Compliance Section of IRO-004.

Existing reliability standards do not adequately address the requirements for the submission of system operational data, used in Available Transfer Capability calculations, the Transmission Loading Relief application, and power system applications, from Balancing Authorities, Transmission Owners/Operators, Generation Owners/Operators, and Load Serving Entities to their Reliability Coordinator.  Section A, (System Data Exchange (SDX) — Eastern Interconnection), of the Reliability Coordinator Reference Document, addresses the submission of specific system operational data, including the timing associated with the submission of the data.  However, the data submission specifications outlined in the Reliability Coordinator Reference Document are not uniformly followed within the Eastern Interconnection.  Therefore, the IDCWG and the ORS support a revision to IRO-004 to require timely submission of system operational data.
