2 Industry Desire to Retire R2 May 6, 2015 – Request to retire Requirement R2 of BAL-002-WECC- • 2 submitted to WECC Standards Committee. August 12, 2015 – Drafting Team selected • James Wells (LDWP), Ken Otto (WAPA), Rick Lowther (SRP), Robert – Johnson (PSC), David Kirsch (BPAT), Ali Miremadi (CAISO), David Frederick (SRP), John Tolo (TEPC) and Don Badley (NWPP). October 22 to December 8, 2015 – The proposal to retire R2 was • posted for comment. 3 comments received, all positive. – December 17, 2016 – DT decided to request a Field Test and waiver. • January 17, 2016 – Request for Field Test and compliance waiver • given to Steve Rueckert, WECC Standards Director, for processing. Now – seeking WECC Operating Committee Approval. • W E C C E S T E R N L E C T R I C I T Y O O R D I N A T I N G O U N C I L
3 Proposed Field Trial • Compare Disturbance Control Standard (DCS) metric performance during Field Test to prior performance. – Question 1: is DCS performance affected by removing Requirement R2? – Question 2: if DCS performance is affected, is it due to removal of Requirement R2?

4 BAL-002-WECC-2, R2 R2. Each Balancing Authority and each Reserve Sharing Group shall maintain at least half of its minimum amount of Contingency Reserve identified in Requirement R1, as Operating Reserve – Spinning that meets both of the following reserve characteristics. [Violation Risk Factor: High] [Time Horizon: Real-time operations] 2.1 Reserve that is immediately and automatically responsive to frequency deviations through the action of a governor or other control system; 2.2 Reserve that is capable of fully responding within ten minutes.

5 BAL-002-WECC-2, M2 M2. Each Balancing Authority and each Reserve Sharing Group will have dated documentation that demonstrates it maintained at least half of the Contingency Reserve identified in Requirement R1 as Operating Reserve – Spinning, averaged over each Clock Hour, that met both of the reserve characteristics identified in Requirement R2, Part 2.1 and Requirement R2, Part 2.2.

6 Foundational Concept and Facts • Purpose – R2 was designed to assure that a declining frequency resulting from a generation loss is arrested. • FERC refers to BAL-002-WECC-2 R2 as a “fill-in-the-blank” metric because it is not results-based (i.e., there is no performance measure). • Purpose – BAL-003-1 Requirement R1 is designed to assure that a declining frequency resulting from a severe generation loss is arrested before the first step of UFLS is reached. • BAL-003-1 is a results-based performance standard. • BAL-003-1 R1 will be implemented on December 1, 2016 • BAL-003-1 R2, R3 and R4 were implemented on April 1, 2016 W E C C E S T E R N L E C T R I C I T Y O O R D I N A T I N G O U N C I L
7 The Next Step • Next Step, pending WECC OC approval – Send request for Field Test and compliance waiver to WECC Standards Committee. Request implementation by August 1, 2016. • Send approved request to WECC Compliance. • WECC Compliance will send request to NERC Compliance. – Compliance waiver for Requirement R2 granted/not granted. – W E C C E S T E R N L E C T R I C I T Y O O R D I N A T I N G O U N C I L
