2014 Review Material
Material from the 2014 reviews of the 'interconnection' of the gas trading markets and physical interconnections is presented below:
In relation to the gas market interconnections we note that the introduction of a gas trading market is a significant step towards achieving the Government’s policy objective of efficient arrangements for short-term trading of gas. We find no issues requiring intervention, but note that the Maui pipeline owner is concerned that market trading may cause pipeline balancing issues. While acknowledging these concerns, we consider that the risks arising from the introduction of the market are manageable. We will keep track of balancing metrics in the immediate future to identify any emerging problems.
In relation to the physical interconnections we find that the owners of the Maui and Vector transmission pipelines now each have very comprehensive interconnection policies, procedures and documentation in place, closely aligned with the Interconnection Guidelines Gas Industry Co published in 2009. The recent interconnections have all been effective, with pipeline owners and interconnecting parties working collaboratively. We will be discussing the few issues that did emerged with the pipeline owners, and propose to continue monitoring new connections.
In 2013 we updated the Minister on interconnection activity, noting that two interconnections to the Vector pipeline had occurred, but that significant interconnections to the Maui pipeline were not expected to occur until early in 2014, and that Gas Industry Co will provide the Minister with an update at that time. We also noted that we would report on the ‘interconnection’ of the gas trading markets.
2011 Request for further review
Gas Industry Co advised the Minister of the efforts made by pipeline owners to improve their interconnection processes to align with the Guidelines and objectives of the Gas Act and GPS, the Associate Minister of Energy and Resources requested that we '…undertake a formal review of the current interconnection arrangements after the next two interconnections to each of the transmission pipelines, or by the end of 2013, whichever is sooner'.
