The reference point for the AGC will be the net plant <br /> revenue meter(s) on the generator step-up transformer(s). <br /> Plant data will be communicated to Pacific Gas & Electric (PG&E) and CAISO. The inputs <br /> required must be provided by PG&E/CAISO and an example is indicated in the table <br /> below: <br /> INPUTS REQUIRED <br /> ITEM STATUS/UNITS MW MVAR MW MVAR COMMENTS <br /> HR HR <br /> T-Line Revenue Ok/trouble X X X X <br /> Metering Point each <br /> GSUT High Side kV <br /> voltage <br /> GSUT High Side Hz <br /> Frequency <br /> High Voltage Circuit Open/close/trip <br /> Breaker(s) <br /> AGC Set Point MW Feed back <br /> AGC High and Low MW <br /> Limits <br /> Generator Circuit Open/Close/Trip <br /> Breaker CTG <br /> Generating Unit On/Off, AGC X X X X <br /> each enabled <br /> High Temperature Deg F <br /> Control Limit <br /> Gas Turbine Inlet Air Deg F <br /> Temperature <br /> Ambient Air Deg F <br /> Temperature <br /> Net Plant Fuel Flow MMBTU/Hr and <br /> Standard Cu- <br /> Ft/HR <br /> Auxiliary Power X X X X <br /> Lodi Energy Center 3.5 - 1 LEC AFC <br /> 071608 Rev.A <br />
