  1. WECC Member Advisory Committee WECC Standards Committee Request for Guidance Governor Droop October 16, 2013

  2. WSC - Request for GuidanceSAR Disposition • WSC Charter • Determining whether a Standard Authorization Request (SAR): is within WECC’s authority to develop (scope); is appropriate for development by WECC; and provide a drafting team with a description of the document to be drafted and an explanation as to why the document is needed.

  3. WECC-0098 Governor DroopBackground • WECC-0098 SAR Filed • In response to RCWG/RPIC recommendation • Review the existing Governor Droop “RBP” • Recommend whether it should become a “Standard” • Specifically – address “Droop” • DT convened • Drafted “Version 1”

  4. WECC-0098 Governor DroopVersion 1 – Out of Scope • WECC-0098 Version 1 • Looked at BAL-003 and ERCOT’s “Droop” Standard • Opted for a different remedy • Use Frequency Response Obligation as opposed to a specified mechanical setting • WSC ruled the Version 1 approach “Out of Scope”

  5. WECC-0098 Governor DroopVersion 1 Valued Approach • Is the WECC-0098 Governor Droop SAR overly discriminatory? If yes, should it be retired in favor of a less discriminatory approach? • Doesn’t address units without governors • Doesn’t address “non-traditional” generators • Doesn’t include “other resources” that may be able to respond in support of frequency

  6. WECC-0098 Governor DroopVersion 1 Valued Approach • If the SAR is not retired, should the SAR be developed at NERC or at WECC? • Is the “Droop” remedy better addressed at NERC or WECC? • NERC is engaged in collection of “frequency-related” data in the East / Invites WECC • NERC’s target • Create a Guideline • See if it works • Consider drafting a Standard

  7. WECC-0098 Governor DroopVersion 1 Valued Approach • If developed at WECC, should the WECC-0098 SAR move forward as drafted or should it be retired in favor of pursuing the Frequency Response Obligation (FRO) approach suggested in Version 1? • FRO or a “Droop”?
