  1. Gary NolanInterchange Scheduling and Accounting Subcommittee Chair Enhanced Curtailment Calculator Joint Taskforce

  2. Background • Efficient Dispatch Toolkit has two distinct parts: • Enhanced Curtailment Calculator • Energy Imbalance Market • The ECC can exist on its own. The EIM requires the ECC to function. • Is there benefit in proceeding with the ECC regardless of the outcome of the EIM?

  3. Purpose of proceeding now • New ECC tool would provide compliance with pro forma tariff provisions surrounding transmission service curtailment priority. • It would be more broadly applied to grid elements nominated by providers and Reliability Coordinators. • Allocate curtailment responsibility to native, network, and untagged loads.

  4. Next Steps • “To provide clarity to the ECC project, its scope, and potential member benefits; the development of tool specifications, discussion, and coordination are needed by subject matter experts.”

  5. Next Steps • Operations Committee and the Market Interface Committee establish a joint task force to further explore and develop the ECC proposal.

  6. Taskforce members selected • Operating Committee wanted participation from key subcommittees: • Unscheduled Flow Accounting Subcommittee • David Lunsford / CAISO • Operating Practices Subcommittee • Carl Dobbs / WAPA - Sacramento • Interchange Scheduling and Accounting Subcommittee • Brenda Ambrosi, In-coming Chair / BCHA

  7. Taskforce members selected • Those representing the MIC are: • Raj Hundal / Powerex • David Lemmons / Xcel Energy • Doug Reese / TSGT • WECC Reliability Coordination will have a representative • WECC Staff Liaison is Craig Williams.

  8. End State • The goal of the task force will be increased system consistency and reliability as the primary objective. If the ECC project is implemented the task force may become a Work Group and roles would need to be re-evaluated.”
