This change will introduce a process to enable GDNs to review, authorise and approve the application for the creation of MPRNs on IGT CSEP sites where the CSEP will exceed the agreed demands aligned to obligations set out in IGTAD B 2.2.1 (c).

Upon submission of the request by the IGT to amend or add Supply Meter Points to the existing IGT network that exceeds the original agreed demands, the DN will be notified and have 10 Business Days to confirm the creation of the Supply Meter Point. If after 10 Business Days, the DN does not respond to the request then the MPRNs are automatically created using existing processes. This process seeks to confirm the release of the maximum number of MPRNs provided on the CCN and CUN files.

The GDN may reject any Supply Meter Point creation request if it is unable to provide the capacity required and, in this case, it will provide a reason to the IGT. Subject to system constraints, the DN can provide partial capacity, and this will be communicated through the review process.

At ChMC on the 10/4/2024 the committee prioritised Part B to go into design and removed Part A from the Scope of this Change Proposal.
