Western Electricity Coordinating Council Seams Issues Subcommittee Chair, Jerry Smith (AZPS) Report of Findings Seams Issues Evaluation California Independent System Operator Market Redesign and Technology Upgrade

Western Electricity Coordinating Council Why an Evaluation? SIS Mission is to Identify, Evaluate, and Propose Solutions to Seams Issues in the WECC Cal ISO MRTU Conditionally accepted by FERC Member concerns about potential seams issues FERC Technical Conference on Seams Issues held December 2006 in Phoenix – SIS Chair, Jerry Smith reported SIS evaluation already underway

Western Electricity Coordinating Council SIS Findings Congestion Management Real-time congestion management issues exist in the WECC today, are an interconnection-wide issue, and are not specifically related to MRTU. Resource Adequacy Resources The CISOs treatment of export schedules under MRTU is consistent with general operating practice in the WECC. Market Timing/E-Tagging/Scheduling MRTU does not create any new seams issues related either to e-tagging or market timelines.

Western Electricity Coordinating Council SIS Findings Congestion Revenue Rights The SIS does not find specific new seams issues related to CRRs. LMP impact on System Operations The current system monitoring processes in the WECC are sufficient to maintain the integrity of the interconnection. Parallel Operations during Cutover The SIS is satisfied the FERC required Readiness Certification, that will include a Cutover and Reversion Plan, should be sufficient to address concerns related to a failure of the MRTU software.

Western Electricity Coordinating Council SIS Overall Conclusion The SIS finds no specific seams issues, appropriate for regional solutions, that are either created by MRTU or existing seams issues that are substantially worsened by MRTU implementation.

Western Electricity Coordinating Council WHY DOES THE BOARD CARE?? California ISO – Market Redesign and Technology Upgrade –The SIS has done its homework on MRTU The implementation of MRTU will create no new regional seams issues which could affect reliability of the Interconnection FERC stated concerns with the implementation of MRTU –Concerns have been addressed
