Assessment of SOR Performance. In order to assess the quality of delivery of SOR when required by the Power System, the Providing Unit will be monitored and assessed during an Event by the Company. The assessment of SOR performance is carried out during the entire SOR time range of T+15 seconds to T+90 seconds (the “SOR Period”). The value of the SOR Performance Scalar will be determined based on whether the result of the Performance Assessment is a Pass or Fail.
Assessment of SOR Performance. In order to assess the quality of delivery of SOR when required by the power system, the Generating Unit will be monitored and assessed during a Frequency Event in accordance with this Section 4 and the provisions of OC11.5.5 of the Grid Code (Spinning Reserve Monitoring) shall not apply to this Agreement. The assessment of SOR performance is carried out during the entire SOR time range of T+15 seconds to T+90 seconds (the “SOR Period”). SOR Charges will be applied based on the extent of the difference between the Expected SOR and the Achieved SOR for the Generating Unit. The Expected SOR is determined for each sample point during the SOR Period and compared to the Achieved SOR. If the Achieved SOR is less than the Expected SOR, 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 SOR 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.
