The objective of Gas Industry Co's pipeline balancing work is to identify where transmission balancing arrangements fail to support the safe, efficient and reliable delivery of gas. Pipeline balancing arrangements have been evolving since the inception of the Maui Pipeline Operating Code (MPOC) in 2005. The current arrangement, known as Market-Based Balancing (MBB), was introduced on 1 October 2015. We expect it to be replaced by a new balancing arrangement, integral to the new Gas Transmission Access Code (GTAC) arrangments that First Gas aims to introduce on 1 October 2020.
Information about MBB is found under Current Arrangements, including Gas Industry Co's 2016 review of MBB, stakeholder submissions on that review and a subsequent follow-up paper on the costs on implementing MBB.
Under Developing there is no current activity to report on. We expect the next activity on this work programme will occur after First Gas introduces its new transmission access regime which it aims to do on 1 October 2020. Once there is sufficient experience of those new arrangements it may be necessary to re-assess the effectiveness of the balancing arrangements.
Under Background we describe the history of how the balancing arrangements have evolved, including a link to our August 2014 report ‘Transmission Pipeline “Balancing 2006-2014’.
