NOTICE TYPE:  M-D111308-02 Legal Notification
SHORT DESCRIPTION:  Withdrawal of November 13, 2008 Protocol Clarification/Interpretation on Reactive Power Capability Requirements Due to Procedural Deficiency
INTENDED AUDIENCE:  ERCOT Market Participants
DAY AFFECTED:  Not Applicable
LONG DESCRIPTION: On November 13, 2008, ERCOT issued a Protocol Clarification/Interpretation (attached) regarding subsection (2) in Protocol Section 6.5.7.1, Generation Resources Required to Provide VSS Installed Reactive Capability, and subsection (5) in Protocol Section 6.7.6, Deployment of Voltage Support Service, surrounding Reactive Power capability requirements.

Since that time, ERCOT has discovered that it failed to follow the full procedural requirements in P.U.C. Substantive Rule 25.503(i), Official Interpretation and Clarification Regarding the Protocols, before issuing its November 13, 2008 Protocol Clarification/Interpretation on Reactive Power capability requirements.  Specifically, P.U.C. Substantive Rule 25.503(i)(3) requires that ERCOT consult with Public Utility Commission of Texas (PUCT) Staff before issuing an official Protocol Clarification/Interpretation.  ERCOT Staff neglected to consult with PUCT Staff prior to the issuance of the Protocol Clarification/Interpretation.  As such, ERCOT  withdraws the November 13, 2008 Protocol Clarification/Interpretation on this limited procedural issue.  ERCOT's opinion of the ERCOT Protocol Reactive Power capability requirements is unchanged.
ERCOT has informed the submitter of the Protocol Clarification/Interpretation Request (PIR) of the procedural deficiency in the November 13, 2008 Protocol Clarification/Interpretation.  If the submitter continues to request an official Protocol Clarification/Interpretation, then ERCOT will follow the full procedural requirements in P.U.C. Substantive Rule 25.503(i) before issuing any further Protocol Clarification/Interpretation on this issue.
