Operational Requirements Unit Telemetry Visibility Each resource participating in the CAISO’s Ancillary Services markets or any Eligible Intermittent Resource or any resource providing Energy with a capacity of 10 MW or greater that is not exempt pursuant to the CAISO Tariff must provide telemetry data according to the point matrix specified in Section 7. This BPM will be revised should additional data points be required, pursuant to CAISO Tariff Section 7.6.1(d). Performance Monitoring Direct Telemetry Timing Requirements The timing diagram (Figure 1) the performance and timing requirements a Generating Unit connected to the CAISO EMS must meet. A Generating Unit must be able to accept and processing direct digital control (DDC) signals (Set Point) within the CAISO time standard (two-second maximum from CAISO’s EMS to output of RIG). The two-second maximum includes any Generator or party” owned communication equipment located between the “third CAISO ECN and Generating Unit. A Generating Unit must be able to send SCADA data to the CAISO within the CAISO time standard (two seconds from the input of the RIG to the CAISO EMS). The governor or controller must receive the signal from the RIG within the CAISO time standard (another two seconds from output of RIG to governor controller). The time standards also apply in the return direction resulting in a total maximum of eight seconds round trip for the signal to travel from the CAISO EMS to the Generating Unit governor controller and back. The timing requirements from the CAISO EMS to the plant control system (e.g. DCS, RTU) through the use of non-CAISO communication equipment must meet the CAISO two second time standard in one direction. The timing requirements from the plant control system back to the CAISO EMS through the use of non-CAISO communication equipment must meet the CAISO two second time standard in the return direction. PDR Timing Requirements The provisions of Section 6.2.1 shall apply to PDR telemetry, except that all references to timing in Section 6.2.1 are increased to one minute.
