Future of OASIS II Conference Presented by Karl Tammar – NYISO For the ISO/RTO Council March 29, 2005 ISO/RTO Activities and Initiatives
OASIS II Issues and Goals: Many Transactions Crossing RTO Boundaries Numerous Customers doing business with multiple RTOs Remove barriers to the ability to trade Standardizing Electronic Communication in Electric Industry Develop effective processes and tools
Periodic Model Updates Load Forecasts Real-Time Values Constraints Approval Requests Operating Information Economic Unit Set Points NetIntertieSchedule Generation Supply Curves Request Approvals Operating information Market Information Settlement Reports Offers & Bids Bilateral TA Meter Data PlanningScheduling and Dispatch RegulationTransaction Management SettlementsMarket Monitoring Regional Market Participants Local Control Center Functions Periodic Model Updates Load Forecasts Real-Time Values Constraints Approval Requests Operating Information Economic Unit Set Points NetIntertieSchedule Generation Supply Curves Request Approvals Operating information Market Information Settlement Reports Offers & Bids Bilateral TA Meter Data PlanningScheduling and Dispatch RegulationTransaction Management Settlements and Billing Market Monitoring Regional Functions Market Participants ISO/RTO Basic Functions: Demand Response and Retail Access Local Security Automatic Generation Control Data Acquisition Dispatch Gateway Functions
Seams Issues barriers and inefficiencies equipment limitations differences in market rules and designs operating and scheduling protocols, other control area practices inhibit or preclude the ability to transact capacity and energy across control area boundaries.
Regional Seams Initiatives Related to Transaction Scheduling Northeast – IESO, ISO-NE, NYISO, & PJM Removal of Export Charges between control areas (Rate Pan-caking Elimination) E-Tagging Integration- automated response on incoming E-Tag requests and automated updates for bid /schedule changes to the E-tag system resulting from the hour-ahead evaluation. Facilitated Checkout Midwest – MISO & PJM Rate Pan-caking Elimination Congestion Management (improve real-time use of transmission interfaces – Regional Dispatch Coordination) West – SSG-WI: AESO, CAISO, RTO West participants & West Connect participants SSG-WI evaluating proposals and previously submitted white papers Single Market Interface (SMI) work is ongoing
Adopted and De Facto Standards ICCP – Real Time Reliability E-Tag – Blends Reliability & Business OASIS 1A – Physical Transmission Business CIM – Quasi Static Reliability CME – Market Extensions to CIM FCO – Application implementation RTO OASIS/MIS – Market Participant Interface

ISO/RTO Activity: Facilitated Transaction Checkout Tool for data exchange to support real-time transaction checkout Each Area provides a service that enables neighboring CAs to view their current transaction stack Areas can integrate this data into existing displays to meet the unique needs of their own Operators Changes made on FTC screen seamlessly carry into current scheduling software Supplemental data (e.g. Ramp info) may be added for one Control Area and available for all without it being required for all. Application Implementation Open Architecture (free code sharing) No monthly fee or upgrade costs to third party Total Project cost is limited to internal development time and server costs (45 to 60K US dollars) Project Costs are quickly recovered with reductions in additional staff required for checkout
Goals of CIM for Market Extensions (CME) Project Extend the CIM architecture to support SMD and facilitate markets Focus on the Day-Ahead and Real-Time Market Processes to define extensions needed for the CIM data model to support these processes Standardize information format and application interfaces to make the North American wholesale electricity market run efficiently, reduce seams issues and save substantial costs in the development of applications for each RTO Will allow RTOs to buy best-of-breed applications and communicate with Transmission operating Organizations and/or other ISOs/RTOs in a standard information format Will allow marketers, Load Serving Entities (LSE), and Generator Serving Entities (GSE) to access information and bid in the RTOs preferred format
Scope of CME Project RTO A ISO DRTO C ISO B Generators Loads Marketers CIM extensions in scope for CME XML information exchange model and terms database – message standards to be developed as part of RTO/ISO Data Initiative Market, Load, Generation Participants CIM extension and information exchange model – Other Initiatives and/or Future Phase(s) Inter-ISO/RTO Messaging MIS SCUCSCED Settlement Intra-ISO/RTO Messaging RTO A
