Modification 0665 has been raised and seeks to amend the current Class 2 Ratchet Charging Arrangement and it allows Transporters designate Supply Points (Network Designated) that should, in addition to mandatory Class 1 Supply Points, be subject to the existing Class 1 Ratchet Charging Arrangement. It is expected to be voted on by UNC Panel in March with final approval by Ofgem in April 2019.

This Change Proposal has been raised to deliver the system requirements set out within this modification. Due to the proposed timescales and the requirement to implement the changes by 01 October 2019, the Change Proposal has been raised ahead of the modification being officially approved.

Part A will be implemented as a part of Minor Release Drop 5 on the 7th September 2019 

Part B has a proposed implementation of November 2020 Release, information about this Release can be found here.
