Assessment of TOR1 Performance. In order to assess the quality of delivery of TOR1 when required by the Power System, the Providing Unit will be monitored and assessed during an Event by the Company. The assessment of TOR1 performance is carried out during the entire TOR1 time range of T+90 seconds to T+300 seconds (the “TOR1 Period”). The value of the TOR1 Performance Scalar will be determined based on whether the result of the Performance Assessment is a Pass or Fail.
Assessment of TOR1 Performance. In order to assess the quality of delivery of TOR1 when required by the power system, the Generating Unit will be monitored and assessed during a Frequency Event in accordance with this Section 5 and the provisions of OC11.5.5 of the Grid Code (Spinning Reserve Monitoring) shall not apply to this Agreement. The assessment of TOR1 performance is carried out during the entire TOR1 time range of T+90 seconds to T+300 seconds (the “TOR1 Period”). TOR Charges will be applied based on the extent of the difference between the Expected TOR1 and the Achieved TOR1 for the Generating Unit. The Expected TOR1 is determined for each sample point during the TOR1 Period and compared to the Achieved TOR1. If the Achieved TOR1 is less than the Expected TOR1, the deficit is summated for all the Event Recorder sample points and an average deficit produced. If a deficit remains after the application of the Applicable Tolerance a TOR1 failure is recorded. Where a Frequency Event has occurred while the Generating Unit was Synchronised to the power system, the Generating Unit response to any further Frequency Event occurring within 5 minutes after the end of the Frequency Event will not be taken into account for settlement purposes.
