Future Of OASIS Conference March 29, 2005 WEQ EC created the ESS & ITS August 5, 2003 Meeting Minutes, Philadelphia, PA Ms. McQuade clarified the Executive Committee has established two subcommittees, the Technical Subcommittee and the ESC Subcommittee, to serve as a home for any ESC/OSC deliverables found to be within NAESBs business standards development scope, and also to address requests that would have been made to the ESC/OSC regarding business standards issues. The establishment of these subcommittees creates an opportunity for ESC/OSC participants to continue their work within the NAESB framework, where appropriate. Additionally, she noted a goal would be to maintain existing ESC/OSC leadership and participation. Ms. McQuade stated this information will be presented at the ESC/OSC meeting on August 25 in Vancouver.

Future Of OASIS Conference March 29, 2005 OASIS II Where to begin….. Started with the ESCs Use Cases. Recognition that multiple markets exist and will continue to exist for some time Dont make it market specific But ensure communication between entities Provide for the acquisition of rights Provide for that elusive concept electronic scheduling Use the latest and greatest technology Make it transparent where necessary

Future Of OASIS Conference March 29, 2005 OASIS II ESC Use Case Specification (280 pages) These Use Cases, along with the OASIS Phase II System Requirements, are envisioned to be used by the Industry as a foundation for specifying the data communications protocols and standards to be adhered to in developing the specific information systems required by OASIS Phase II (OASIS II). Unlike the situation with OASIS Phase I where the term OASIS has been synonymous both with a standardized programmatic interface (i.e., templates) and the computer system implementing that standard interface, this document makes no assumption that OASIS II will be one or multiple computer systems or databases. In the context of this document, the term OASIS is meant only to refer to a single, common, standardized Market Participant interface for the exchange of information with the market.

Future Of OASIS Conference March 29, 2005 OASIS II ESC Use Case Example

Future Of OASIS Conference March 29, 2005 OASIS II OASIS II Vision Statement (circa July 2004) OASIS II will facilitate the timely scheduling of physical energy transfers, and the tracking of both energy and transmission rights usage with regard to those transfers. Given the range of market structures and regional practices among potential users, OASIS II will provide flexibility for the scheduling and tracking of transmission, energy and ancillary service transactions to meet both NERC reliability standards and NAESB business practice standards. All OASIS II systems will support real-time status updates for current schedules/transactions, permit audits and analysis of historical transactions and comply with FERC requirements for information postings as well.

Future Of OASIS Conference March 29, 2005 OASIS II OASIS II Vision document, ver. 1, published July 13, 2004 OASIS II will: Facilitate Procurement of Energy and Ancillary Services Facilitate Procurement of both Physical and Financial Transmission Rights Facilitate Electronic Scheduling of Physical Transactions Accommodate Financial Only Contracts Accommodate Regional Diversity Support Reliable System Operations Accommodate Market Operations for Centralized Markets Accommodate Data Publishing to Industry Support Market Monitoring Provide Standards for Electronic Data Communication and User Interfaces Function Consistently and Reliably Implement in a Cost-Effective Manner

Future Of OASIS Conference March 29, 2005 OASIS II OASIS II Scope document, ver. 1, published July 13, 2004 The interaction between market participants and various power markets, including both existing 888-style Transmission and Ancillary Service markets as well as more centralized transmission and energy markets. The submission of Market data to the Interchange Authority (IA) as described within the NERC functional model; in other words, the manner in which the IA receives transactions. The exchange of Operational data as described within the NERC Reliability Functional Model; in other words, communications involving the Balancing Authority (BA), Reliability Authority (RA), Transmission Service Providers (TSP), Interchange Authority (IA) or other Functional Model entities. The scope of OASIS II would not include the development of any reliability policies or standards directly, but would include supporting the reliability goals established by NERC (or other reliability organizations).

Future Of OASIS Conference March 29, 2005 OASIS II OASIS II Scope document, ver. 1(continued) The data exchanged between marketers when writing a transaction; in other words, the process through which marketers build source to sink transactions and request their implementation (i.e. scheduling). This means defining standards that could be used to exchange information between the parties involved in the transaction. The process through which both market and operation entities exchange reliability information, such as outages, system topology, and other significant data. The coordination of the implementation of Industry cyber-security standards with regard to securing these systems. The provision of a mechanism through which the confidentiality of any data is preserved. The exchange of settlements and billing data. This is not considered a high priority, but rather a strategic direction and goal for later development.

Future Of OASIS Conference March 29, 2005 OASIS II Joint OASIS II Implementation Task Force (circa July 2004) Develop the following documents: OASIS II Use Cases, which will describe all in-scope business processes, business objects, and their associated logic; OASIS II Requirements, which will support the Use Cases by detailing specific requirements and metrics; OASIS II Structural Design, which will describe the technical architecture and how functionality will be staged for deployment; and OASIS II Implementation Plan, which will indicate the order and timeline of how the stages will be specified, developed, and deployed.

Future Of OASIS Conference March 29, 2005 OASIS II This past January the Joint OASIS II Implementation Task Force formed a Publish/Subscribe Group to continue development of the Publish/Subscribe Use Case. The new groups vision statement: The Publish and Subscribe initiative will provide a flexible infrastructure through which electric utility industry participants can request and receive information on an event-driven or scheduled basis. It will utilize the OASIS II "Foundation Technologies," i.e., HTTP, XML, SOAP, PKI etc... and will be an upgrade that can apply to both future and current uses of the system. Although it is being developed as a part of OASIS II, it is intended to structure this initiative such that it can be implemented as a part of OASIS I or even as an independent standalone system
