1. Transmission Workstream 05 November 2009
Draft Modification Proposal – Enabling the Partial Assignment of Registered NTS Exit (Flat) Capacity
Transmission Workstream November 2009

2. Background
Mod Proposal 0263 raised by BGT to introduce partial assignment of exit capacity into the UNC
Discussed with industry at various workstream meetings and with ourselves independently
0263 discussed at October workstream which recommended that it was sufficiently developed to go back to panel. Workstream also requested that NTS raise a ROM in 4-6 weeks.
It was the intention of National Grid NTS to raise an alternate modification Proposal to 0263 to be considered at the same time

3. Similarities / Differences between Mod 263 and National Grid NTS’s Proposed Mod
NG’s Draft Proposal
Facilitate partial assignment in the Enduring regime
Only Enduring Annual NTS Exit (Flat) Capacity and Annual NTS Exit (Flat) Capacity can be assigned
Any associated User Commitment with the assigned capacity transferred from Assignor to Assignee
Assignment may be rejected if conflicts with any existing Exit Forward Agreement or Exit Option Agreement
Assignment not permitted where conflicts with any capacity transfer (trade)
Assignment not permitted where conflicts with any capacity transfer (trade)
National Grid to cover costs
User Pays
No reference to demonstration date
NTS Exit (Flat) Capacity subject to a demonstration date will be unable to be assigned

4. User Pays
National Grid NTS is of the view that the introduction of Partial Assignment would be a User Pays service because:
it was not funded as part of Exit Reform
it is a change to services provided by Xoserve
it provides a clear benefit for Shipper Users (as recognised by 0263)
It does not provide a benefit to Transporters

5. Users Pays National Grid NTS will be proposing:
that recovery of any implementation costs for partial Assignment will be:
100% Shipper Users 0% Transporters
met wholly by those Shipper Users that are registered as holding NTS Exit (Flat) Capacity
pro rated based on shipper User’s registered NTS Exit (Flat) Capacity holdings as a proportion of the total registered NTS Exit (Flat) Capacity holdings held by ALL Shippers as of the 1 October 2012 as registered by National Grid NTS on the implementation date of this proposal
one off charge invoiced in the month following introduction of the systems & processes enabling Partial Assignment

6. Next Steps
National Grid NTS will raise a Draft Proposal once indicative costs/timelines are received from xoserve
The Proposal will differ from BGT’s Proposal 0263 only in that:
It is User Pays
It excludes NTS Exit (Flat) Capacity that is subject to a Demonstration date
Assuming relevant costs have been received we propose to submit the Proposal to the November Mod Panel
