In Gas Industry Co's 2006 Transmission Access Issues Review paper we identified access to short-term capacity on the Vector pipeline as an issue. In 2009, a capacity constraint on the Vector pipeline to Auckland and Northland caught some pipeline users by surprise and prompted further Gas Industry Co work as part of the Gas Transmission Investment Programme (GTIP).
While a few improvements have been made, some fundamental problems remain, and the objectives set out in our May 2010 paper: Options for Vector Transmission Capacity remain valid. These are to: ensure efficient pricing of capacity; ensure efficient allocation of capacity; promote efficient investment in capacity; facilitate competition in related markets; favour simple and transparent design and operation; allow price stability; provide the level of service firmness that users require and are willing to pay for; and minimise costs of transition from current arrangements.
As of June 2016, the Maui and Vector pipelines came under the ownership of First Gas Limited, who wish to converge the two access arrangements into a single access regime. We expect that the above objectives will be addressed as part of that redesign.
The Current Arrangements section contains information on the Options for Vector Transmission Capacity paper that considers Vector's options for changing its commercial arrangements for transporting gas on its transmission pipelines and sets out the still valid capacity objectives.
The Developing section contains information regarding the work being undertaken by First Gas and Gas Industry Co to converge the two access arrangements into a single access regime. Here you will find all the recent consultations to do with this single code work. We are currently consulting on the Single Code Options Paper (SCOP2). A First Gas paper Gas Transmission Access Code Development: Proposed Decisions and Next Steps will be discussed at the 28 February Workshop. Details of the Workshop can be found here.
The Background section contains previous work relating to Transmission Access and Capacity including the Bridge Commitments and the original proposal for the GTIP work programme.
