IRCR Monthly 4 Peak Trading Intervals for New Meters

When determining the Individual Reserve Capacity Requirements for Trading Month n, in accordance with Step 5 of Appendix 5 of the Market Rules, the 4 Peak Trading Intervals from Trading Month n-3 are used in the calculation for new meters. A new meter is idenitified as a meter that was not registered with the IMO during one or more of the Hot Season 12 peak Trading Intervals. The intervals are the start of the interval (eg Interval 15:00:00 is the interval from 15:00:00 to 15:29:59). For each new meter, that measures Temperature Dependent Load, a Market Customer can find the contribution towards their IRCR by calculating the median of each new meter's readings, corresponding to the 4 peak Trading Intervals, then convert this into a MW value and multiply this by 1.3 and then multiply by the Total_Ratio.
