Gas Day Harmonisation

In this sectionGas
In early 2017 the AEMC published a rule determination to harmonise the start time of the gas day used in the short-term trading market hubs and the gas supply hub trading locations with the gas day start time used in the Victorian declared wholesale gas market. Under the rule, the gas day in each market at each location will commence at 6.00 am Australian Eastern Standard Time (AEST). This change will also result in standardising the next gas day nomination cut-over time which will be 3pm AEST.
In late 2017 the COAG Energy Council considered a range of reform recommendations put forward by Gas Market Reform Group’s (GMRG) which include harmonising the start time of the gas day. At the November 2017 COAG Energy Council meeting, Ministers agreed with the full package of reforms put forward by GMRG which included a recommendation that harmonising the start time of the gas day changes take effect by 1 October 2019. The relevant National Gas Law (NGL) and National Gas Rule (NGR) changes were made by the SA Minister for Energy on 22 November 2018.
In September of 2018, AEMO kicked-off a program of work to update relevant market procedures and market systems to reflect the new standard gas timetable.
As required by the NGR, AEMO is also consulting on the Transition Plan for gas markets affected by the changes. The transition plan includes general principles for transition that AEMO has used to develop the transition plan.
The NGR also requires affected natural gas facilities to prepare transition plans for their facilities by no later than 30 June 2019. AEMO suggests that affected facility operators follow the general principles for transition included in the gas market transition plans.
