A Confirmation Statement shall be sent to the Service Provider no later than the third Business Day after the Trading Day to which it relates.
1.2 The Company hereby confirms that, before including any Charge in respect of Reserve in a Confirmation Statement, the Company will have considered and taken into account relevant issues including the following:
1.2.1 whether there were any Transmission System disturbances immediately prior to the start of the Frequency Event;
1.2.2 in circumstances where there have been 2 frequency drops within the one Frequency Event, which frequency drop should be considered to be the start point of the Frequency Event;
1.2.3 whether any Dispatch Instructions issued just prior to or during a Frequency Event might have interfered with the free governor action or Unit Load Controller action of the Generating Unit during the Frequency Event;
1.2.4 whether the appropriate Conversion Factors have been used to convert generated output into sent out values (or vice versa);
1.2.5 whether the Event Recorder data requires smoothing by the application of a moving point average to reduce the effect of Transmission System oscillations on the Generating Unit output being considered;
1.2.6 whether the Generating Unit was operating in accordance with a Dispatch Instruction to increase Load during the Frequency Event; and
1.2.7 whether the pre-transient load and frequency calculated from the averaged -60s to -30s period differs from the values at minus 5 seconds prior to the start of the Frequency Event the more representative figures shall be used.
