0851R - Extending the Annually Read PC4 Supply Meter Point (SMP) read submission window

Under UNC TPD, M, 5.9.4, Shippers have 25 Supply Point Systems Business Days (SPSBD) after the read date to submit a read for settlement. Where there's an issue preventing the read from being validated, and that issue is not resolvable within the 25 SPSBD timeframe, the read becomes unusable. This is highly problematic for meter reads that are hard to retrieve. It needs addressing because enabling valid reads to be entered into settlement decreases settlement imbalance, unbilled, Unidentified Gas (No reads at Line in the Sand is a UIG contributor), manual AQ fixes, repeated costs for additional site visits, and time and money spent on must-reads.
