The revised RIIO-2 Failure to Supply Gas (FSG) arrangements will reduce the timescale for the FSG process e.g. compensation payments from fortnightly to weekly.

Automate the FSR file (Mod0565) manual workaround, including the reporting (for output to DNs) for those MPRNs > 73,200 kWh i.e. on transfer from domestic to I&C FSG compensation payment threshold

Note: This change was originally in the scope of XRN5080 (within Option 2) however, due to delivery time constraints, ChMC agreed (11th Nov ’20) to descope this element and, that a new change proposal should be raised.
