This document serves as a request for guidance from the WECC Member Advisory Committee regarding the Standard Authorization Request (SAR) for Governor Droop, submitted by Governor Droop on October 16, 2013. It evaluates the appropriateness and authority of WECC in developing the standard, focusing on the existing regulatory framework and the implications of adopting a new standard for frequency response obligations.

  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”?
