Summary

This Change Proposal has been raised to deliver the requirements set out under IGT UNC Modification 159V – Amendments to the must read process.

This Modification was raised to update the IGT must read process to include timescales for a site to enter the process and to introduce timeframes for procuring and returning a read that align with read validation.

The Change Proposal will amend the IGT must read process in line with the Modification IGT159V requirements which includes the following:

• Placing a timeframe on the must read being provided by the IGT to ensure is aligns with the current validation window.

• Allowing Shippers a mechanism to exclude SMPs from the IGT must read process which have a known meter issue preventing reads being obtained.

• Excluding SMART, AMR and DCC Active SMPs from being included in the IGT must read process.

• Where there is a SoLR or Change of Shipper event, allow a 4 month pause in the relevant SMP(s) entering the IGT must read process.

• Ensuring PAC are provided the relevant information about the IGT must read process.

Please note, Ofgem approved the implementation of IGT159V on the 02 December 2022.
