The NTS Throughput value for Gas Day 5th November (published on D+1) was incorrect. This was due to erroneous demand data that was identified and corrected on D+1. Unfortunately however, the file used to generate the SISR04 report had already been sent to the IE3 Website. Therefore, the revised (corrected) value did not automatically feed into the SISR04 report until the report was published on D+2.

We are investigating possibilities of improving the above process, but in the meantime it is recommended that users compare the NTS Throughput in SISR04 with the Actual EOD System Demand published within the NORD01 Report (Daily Operation Information section).
