Summary
This change has been raised to deliver the requirements set out under UNC Modification 0854 – Revision of Virtual Last Resort User and Contingent Procurement of Supplier Demand Event Triggers.
This Modification has been raised to allow the utilisation of Revision of Virtual Last Resort User (‘VLRU’) and Contingent Procurement of Supplier Demand (‘CPSD’) mechanisms where a User is subject to UK Government sanctions.
The Change Proposal will implement a process to deliver the Modification 0854 requirements which involve the following:
- National Gas Transmission can issue a User Premises Termination Notice (UPTN) when a User is sanctioned by the UK Government..
- Once National Gas Transmission have issued the UPTN, the CDSP will issue a notice to the industry (on NG NTS’s behalf) stating that the relevant User has become a Premises Termination User (PTU).
- The existing User Termination process will be mirrored for a Premises Termination User with the exception that the User MUST be suspended and not terminated (i.e. it will remain party to the UNC).
- In respect of the relevant Supply Points, the VLRU and CPSD processes will be available to Supplier (acting under a DoU) and National Gas Transmission respectively.
- All CDSP systems and services will be suspended for the Premises Termination User from the UPTN effective date which is anticipated to fall in line with the start of the next applicable Gas Day.
- RECCo and the Central Switching Service will be responsible for determining next steps re. their own systems and services for the Premises Termination User.
- For NTS Supply Meter Points the NTS Exit Capacity should not allow the Premises Termination User to offtake gas.
Please note, Modification 0854 is subject to Authority Decision which means the decision on approval or rejection is with Ofgem. The timescale for a final decision on Modification 0854 is currently unknown.
