1. iGT Agency Services Background
A number of responses to the Nexus consultation in 2008 supported a single agency service for both GT and iGT services
In August 2011 E.On raised iGT UNC modification 039 “Use of a Single Gas Transporter Agency for the common services and systems and processes required by the iGT UNC”
Xoserve was invited to join the 039 work group in December
Working with iGTs, Shippers and GTs it has been concluded that iGT Ageny Services would best be progressed as an eighth business requirements document under Project Nexus
The associated funding and governance topics will be discussed under the 039 workgroup
