1. Enoch DaviesStaff Engineer, WECC BCCS Data Collection Process Proposal Technical Studies Subcommittee May 16, 2013

2. Assumptions • The current data collection process outlined in the Data Preparation Manual will not work with the Base Case Coordination System (BCCS) • The new data collection process should mirror the old process as closely as possible while still utilizing the technological benefits of the BCCS • The new process should clearly define roles and responsibilities of each functional entity

3. Objective • Propose a data collection process to be used in conjunction with the BCCS • Discuss action plan and assignments for updating the Data Preparation Manual • Discuss outreach activities related to the new data collection process

4. Current Data Collection Process • System Review Work Group develops case objectives • Data requests sent out periodically • Base case data requested 11 times per year • Generator test data on a 5 year cycle (no “official” data request) • Data sets e-mailed to WECC staff • Case compiled by WECC staff and prerun case posted for comment • Data changes incorporated into base case and “approved” case is posted on WECC website

5. Potential Problems Using Existing Process • Full loop cases no longer submitted • Current process includes review of submitted data—may not be necessary • BCCS provides accuracy and validation not previously available • Some discussion about long-term use of Area Coordinator role—may need to amend process

6. The New Process • What from the existing process should carry over to the new process? • SRWG develops case objectives • Solved cases must be used to develop profiles • Cases posted for comments (maybe) • Approved cases posted on WECC website • …

7. New Process Proposal • Should be two update processes • Normally static data* (e.g., impedances, dynamics data) • Operationally variant data (e.g., generator dispatch for a specific scenario) • Two processes have different update cycles *Note: This process will change after initial population of the BCCS

8. Normally Static Data Collection Process (Implementation Phase) Primarily: • “Project” Files • Ratings Files • Dynamics Data

9. Normally Static Data Collection Process (Ongoing Process) • Data provided “as needed” • No official data request – similar to current process for Generator Testing Program

10. Operationally Variant Data Collection Process • “Profile” information (loads, generation, reactive devices, interchange, etc.) • Data request for each base case data set • Similar to current base case development schedule • Data provided from a solved case • Includes initial submittal and data review periods

11. Operationally Variant Data Collection Process

12. Items for Consideration in Developing the New Process • What is the role of the Area Coordinator in the new process? Maybe only for specific areas? • How frequently should WECC issue a data request to develop base cases? • Should the base case development process be an ongoing activity or should it be a one-time-per-year process? • How will NERC Standards development (MOD B) affect the new process?

13. Action Plan and Assignment • Assurance Team review and comment • SRWG assignment • Due dates • Potential phased approach • Effect of training on proposed data collection process

14. Outreach • BCCS Training • Webinars • SRWG and MVWG Meeting • TSS Meeting
