Market Design and Operation Working Group

The Public Utilities Office is progressing reforms to improve access to Western Power's electricity Network in the South West interconnected system (SWIS). These reforms are supported by complementary and consequential reforms to the Wholesale Electricity Market, in particular implementation of security-constrained economic dispatch and market arrangements, co-optimisation of energy and ancillary services, and facility bidding for all Market Participants. There are also a number of supporting market design changes that will need to be assessed and developed, including but not limited to reducing gate closure, moving to five-minute dispatch intervals, changes to the participation and registration framework, and consequential changes to the Short Term Energy Market.

On 16 July 2018 the Market Advisory Committee (MAC) agreed to establish a the Market Design and Operation Working Group (MDOWG) to assist the MAC in providing advice to the Public Utilities Office and the Rule Change Panel on these reforms. The MDOWG's scope of work includes consideration, assessment and development of changes to the Market Rules and Market Procedures, in respect to the design and operation of the security-constrained market and dispatch system.

The Public Utilities Office provides the secretariat for the MDOWG. The only standing member of the MDOWG is the Chair, appointed by the Public Utilities Office.

The Terms of Reference for the MDOWG is available below.
