CDWR asks the CAISO to clarify the need for the four new telemetry points.  CDWR believes this information may not be necessary to comply with the new NERC frequency response standard.  Also, these telemetry points would most likely provide static information that only changes when governors are tested and recertified.  Furthermore, some of CDWR’s governors are fifty plus year old and would need to be retrofitted to provide this telemetry information.  Providing these new telemetry points would be a considerable undertaking.

Please see attached document for other CDWR comments.
