©2004 PJM 3 Joint and Common Market Four Phases Phase 1: Coordination of operations to ensure proper congestion management (Market-to-Non-Market) Phase 2: Coordination of Day-Ahead and Real-Time Constraint management (Market-to-Market) Phase 3: Common Market Portal Phase 4: Congestion Management through Integrated Dispatch* * Based on cost/benefits analysis underway

©2004 PJM 4 Joint and Common Market Benefits Addresses FERC Vision: seams elimination, market design standardization, technology standardization Builds on the recommendations from the Aug. 14 Task Force, then goes beyond Significant enhancement to reliability at lower cost Mitigates market power and promotes price transparency

©2004 PJM 9 Technology Standardization Infrastructure Key Components –Data –Architecture Characteristics –High costs, low added value –Considerable overlap –Needs the highest level of protection (Cyber security) Opportunity –Common Design (ITC’s “Reference Architecture”, Data Initiatives) –Build in protection –Collaborative development with system vendors

©2004 PJM 10 Technology Standardization Common Applications Key Components –Business Applications –EMS Characteristics –High costs –Considerable overlap, excessive customization –The differentiation is in the model and the rules, not in the code (i.e. Settlement Application) Opportunity –Converge to the “Reference Architecture” –Collaborative development with system vendors –Platform for next generation EMS?

©2004 PJM 11 Technology Standardization Advanced Technology Key Components –Reliability applications (i.e. Dynamic Security, Super Regional Network Models) –Decision support (i.e. Intelligent Alarming, Visualization) Characteristics –High added value –Insufficient investment Opportunity –Collaborative R&D and shared investments

©2004 PJM 12 Conclusions The industry has responded to FERC’s challenge and is making good progress (ITC, Vendors Consortia) The key challenge is to lower the IT costs in the absence of critical mass, while investing in advanced reliability applications and cyber security The opportunity exists for further software standardization, productization and cost sharing An even bigger opportunity exists in the convergence of platforms, applications and network models
