Assignment of NTS Entry Capacity – Questions relating to High level Business Rules Assignment Workstream, 7th April 2009

2 Questions to consider re High Level Business Rules National Grid NTS has a number of questions that it believes the Industry will need to consider to move Assignment forward, primarily :  whether applies only to QSEC only or is to also include AMSEC?  whether NTS Entry Capacity can assigned to multiple parties?  whether the duration of the NTS Entry Capacity assigned is on an enduring basis or is to be driven by the assigning User?  at what level should the notice period be set at i.e. 10 business days, 1 month etc

3 Issues to be considered There are also a number of issues that National Grid NTS believes should be considered by the Industry:  how will NTS Entry Capacity Trades, Options, Forwards etc be managed i.e. will they be included as part of an assignment?  what will be the implications for Credit Management?  how frequently will an NTS entry Capacity Assignment process be used?  what are the priorities i.e. complexity, frequency of use, cost etc
