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

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?

• 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.

• 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.

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

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.
