1. Assignment of NTS Entry Capacity – Background and UNC Obligations
Assignment Workstream, 7th April 2009

2. Background
National Grid NTS has been asked by the Industry to consider the concept of NTS Entry Capacity Assignment:
“the transfer of financial liability in addition to the entry capacity entitlement”
The concept of NTS Entry Capacity Assignment has been discussed at the following forums:
Transmission Workstream
Review Group 221
Though there has been some discussion of Industry requirements no consensus has been reached
Whilst there are some Assignment provisions within the UNC National Grid NTS has consistently stated that an Assignment process of the complexity indicated by the Industry would be subject to the User Pays process.

3. UNC Obligations…

Where the assigning party is a Shipper they may only assign to another Shipper
The Assigning party may not assign their credit limits such limits must be determined separately for the assignee
The assigning User is liable for all obligations that have accrued up to the date of which the assignment takes place;
