Hourly average LMPs are computed to be the time-weighted average of 5-minute interval Real- Time Ex-Post LMPs. Each interval is assigned a 5-minute weight. For instances where an interval is not available, the weight for the missing interval will be assigned to the last successful interval or the next successful Dispatch interval, as appropriate, within the same Hour. Where multiple intervals within the same hour, but not the entire hour, are missing, the weight for all missing intervals will be assigned to the last successful interval or next successful Dispatch Interval, as appropriate, within the same Hour. For instance, if interval 1225 is missing, intervals 1220 and 1230 will split the weight for the missing interval and each will be assigned 7.5 minutes for the hourly calculation. If intervals 1225 and 1230 are missing, then intervals 1220 and 1235 will be assigned 10 minutes for the hourly calculation. If interval 1205 is missing, interval 1210 will be weighted for ten minutes. If interval 1300 is missing, interval 1255 will be weighted for ten minutes during the hourly time weighted calculation.
