The objective of the GTIP is to:
- ensure that existing and future gas transmission assets are used efficiently;
- establish the need for gas transmission investment; and
- develop an effective pathway for efficient gas transmission investment to take place.
Structure and Governance
The GTIP is structured as a package of interconnected projects:
- Information Projects:  to minimise information asymmetries;
- Market Projects : to provide efficient market design; and
- Regulatory Projects : to define appropriate regulatory arrangements.
Two advisory panels provide advice to Gas Industry Co in relation to the Programme. The panels are two key ways the industry can be substantively involved in the GTIP, although care will be taken to keep all stakeholders informed of progress, and consulted on critical issues.
The diagram below illustrates the GTIP structure and governance.
GTIP Structure and Scope paper and review
Gas Industry Co has prepared the paper: Gas Transmission Investment Programme - Structure and Scope . The aim of the paper is to provide:
- a clear objective and scope for the Programme;
- further detail on the GTIP governance arrangements and component projects; and
- a detailed work plan.
The scope of projects identified in the paper will be reviewed by the Panel of Expert Advisers (PEA). Any advice the panel has on revising the scope will be considered by Gas Industry Co before the scope of the GTIP is finalised.
Background to this work
Gas Industry Co has been working on transmission pipeline capacity issues for several years. Our work in this area has sought to address both short and long-term issues that have arisen from the North Pipeline constraint. In relation to the short-term, large end users on the North Pipeline have experienced a reduction in the number of credible bids they receive when seeking a new gas supplier. Gas Industry Co's investigation of this situation prompted key industry members to put in place a set of commitments known as the, 'Bridge Commitments' . Gas Industry Co is monitoring the market to assess the effectiveness of these commitments.
More information on this work can be found in the Short-term Capacity Workstream 
In relation to the long-term, Gas Industry Co has investigated Vector's access regime and developed various options for improving the performance of the regime. Stakeholders have participated in this work through various workshops and consultation papers. At an April 2011 workshop, attendees strongly endorsed the need for a more holistic approach to finding solutions to the longer-term transmission capacity issues. It was proposed that Gas Industry Co lead a structured programme of work, and subsequent industry submissions endorsed an outline for the GTIP prepared by Gas Industry Co.
