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. 

Under Current Arrangements you will find information about MBB, including Gas Industry Co's 2016 review of MBB, stakeholder submission 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 a year or so after First Gas introduces its new transmission access regime. We will then assess how effective the new balancing arrangements have been. 

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’.
