Power System 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. These reforms will require substantial changes to power system operations. The design of these reforms will also need to consider other issues, current and emerging, in regard to the management of power system security and reliability, and have sufficient longevity to accommodate the operation of the power system in the longer term.

On 16 July 2018 the Market Advisory Committee (MAC) agreed to establish a the Power System Operation Working Group (PSOWG) to assist the MAC in providing advice to AEMO, the Public Utilities Office and the Rule Change Panel on these reforms. The PSOWG's scope of work includes consideration, assessment and development of changes to the Market Rules and Market Procedures, in respect to the operation of the power system to support the reform program.

AEMO provides the secretariat for the PSOWG. The only standing member of the PSOWG is the Chair appointed by AEMO.

The Terms of Reference for the PSOWG is available below.
