NOGRR064  QSE Acknowledgement of VSS Dispatch Instructions

Approved sponsor Luminant Energy posted 2011-03-08 ercot.com
ReasonTo remove inconsistency between two sections of the Nodal Operating Guides related to the appropriate time period of response by a QSE to a VSS Dispatch Instruction. Furthermore, two minutes is not enough time for a QSE to receive a VSS Dispatch Instruction from ERCOT, then contact the appropriate Generation Resource who then must physically change the voltage at the Generation Resource using whatever means appropriate. This change does not reduce system reliability since existing Nodal Operating Guide language in paragraph (3) of Section 2.2.10, already allows a QSE up to five minutes to respond to a VSS Dispatch Instruction.
