Discussed JGC idea of combining OC and MIC. Western Electricity Coordinating Council

Western Electricity Coordinating Council NERC OC Discussed gas-electric interdependency and the need for closer coordination. GridEx3 exercise continued to show the importance of communication and coordinated response. EPA Clean Power Plan is set for full compliance in 2030. The three basic tenets are: Heat rate improvement for coal fired plants Re-dispatch of natural gas combined cycle plants Increased use of renewable energy. NERC is reviewing the Functional Model Lessons Learned has led to a recommendation of additional lightning protection in areas prone to lightning. Western Electricity Coordinating Council

Western Electricity Coordinating Council WECC BAL-002-2 Field Trial Goal is to evaluate impact of retiring Requirement R2 (Spinning Reserve). BAL-003 FRR is performance based and a much better measure. Conditions to monitor are changes in DCS performance and system wide frequency response. The OC supported moving forward with a field trial. Western Electricity Coordinating Council

Interchange Scheduling & Accounting Subcommittee There are regional practices that are contributing to after-the-fact tags. A white paper will summarize the issues and propose policy changes. A WIT Users Group is being formed. Western Electricity Coordinating Council

Critical Infrastructure Information Management Subcommittee In 2016 to date, there were five significant EMS events, three caused by network infrastructure. Duration of EMS outages seems to be increasing and is greater than in the Eastern Interconnection. NERC EMSWG is planning the 2016 Monitoring and Situational Awareness Conference in Folsom on September 27-28. Western Electricity Coordinating Council

Unscheduled Flow Administrative Subcommittee Proposed that Monthly Qualified Device cost repayment in the Western Interconnection Unscheduled Flow Mitigation Plan (WIUFMP) will be allocated based on the proportion of a Balancing Authority’s NAI absolute values compared to the total for all Balancing Authorities’ NAI during hours of Qualified Device usage. Comments noted the plan potentially ignores significant internal flows and does not recognize the non-impact of HVDC schedules. Motion passed at MIC. OC Transmission Providers approved 10-9-2 but Transmission Customers rejected 4-5-2. Western Electricity Coordinating Council

Operations Training Subcommittee WECC CEH training will be retired at the end of 2016 Several initiatives are on holding pending outcome of OSRTF recommendations. Human Performance Conference will be held November 7-10. Western Electricity Coordinating Council
