Overview

Background

The Gas Transmission Investment Programme (GTIP) was developed by Gas Industry Co in late 2011, at the request of industry participants, to address issues relating to efficient access to, and investment in gas transmission. More detail on the background to the GTIP can be found here under the GTIP Background tab.

Work on the overall GTIP can be found here under the GTIP (All Projects) tab and the associated work of the Panel of Expert Advisers (PEA) can be found here.

The GTIP comprises Market, Information, and Regulatory Projects. Each of these Projects is also discussed in more detail under separate tabs. In particular the Information Projects include development of New Zealand's first gas supply/demand study and a gas demand management study which can be found here.

Latest

Late in 2013, the TSOs responded to Gas Industry Co confirming that they, with support from code signatories and other interested stakeholders, will progress the PEA's proposals for the industry to adopt and operationalise the guiding principles and recommendations.

Gas Industry Co has continued through its policy development and Gas Act processes, by publishing an Options Paper on 23 December 2013. A workshop presenting the Options Paper was held at Gas Industry Co on 12 February 2014. Further details can be found here.

In October 2013, Gas Industry Co released an Analysis of Submissions in relation to:

The Panel of Expert Advisors' (PEA) Second Advisory Report on Transmission Access and Pricing (July 2013)

Gas Industry Co's GTIP Status and Development Report (July 2013)

GTIP Background

Objective

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:

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.

Workshop on Demand Management and Transparency

On Tuesday 15th January 2013 a workshop was held relating to Demand Management and Transparency.

Here are two presentations from this workshop

These are issues that the PEA have provided advice on and their work can be found here

Transmission Update and Workshop on Gas Supply/Demand

Gas Industry Co held two transmission-related sessions on Friday, 18 May, 2012 for industry participants and interested stakeholders. They were held to ensure that stakeholders were up to date on the range of transmission-related workstreams that are progressing, particularly as we move towards the phase of considering options for transmission access arrangements.

Morning session: Transmission Update

The morning session provided an update on transmission capacity work, including a progress report on the Bridge Commitments, an overview of the operation of the Gas Transmission Capacity Trading bulletin board, and a summary of the work undertaken by the Panel of Expert Advisers on transmission capacity access and pricing.

Afternoon session: Gas supply/demand workshop

The afternoon session focussed on the gas supply/demand modelling that Concept Consulting is undertaking as a means of understanding future scenarios for gas demand and thus demand for transmission capacity. This session presented an overview of the modelling approach, describe modelled supply and demand scenarios, and present some preliminary results from the modelling.

The purpose of the supply/demand workshop was to present preliminary results and elicit feedback from stakeholders on the modelled assumptions and inputs. Although this is not a formal consultation, Gas Industry Co would welcome feedback from interested parties on the modelling, including the assumption and information that were used as inputs on the preliminary conclusions reached.
