Wholesale Electricity Market Investment Certainty (WIC) Review Working Group

An active working group of the Market Advisory Committee

Last updated: 22 June 2026

Change of name from WEM Rules to ESM Rules

Since this web page was published, the Wholesale Electricity Market (WEM) Rules have been renamed the Electricity System and Market (ESM) Rules, and the Electricity Industry (Wholesale Electricity Market) Regulations 2004 (WEM Regulations) have been renamed the Electricity Industry (Electricity System and Market) Regulations 2004 (ESM Regulations). Changes have not been made to this web page to reflect this updated name.

In 2023, Energy Policy WA (EPWA), in consultation with the Market Advisory Committee (MAC), commenced the Wholesale Electricity Market (WEM) Investment Certainty (WIC) Review, under clause 2.2D.1 of the Electricity System and Market (ESM Rules).

The WIC Review includes a package of WEM reform initiatives announced by the former Minister for Energy on 9 May 2023 and aims to ensure that the WEM provides incentives for sufficient new renewable generation capacity, while maintaining system security and reliability, and without unduly increasing the cost to consumers.

The Market Advisory Committee established a MAC Working Group to support the review – the WIC Review Working Group.

The Chair of the WIC Review Working Group has the discretion to allow additional subject-matter experts or consultants to attend specific meetings or workshops, either generally or on a case-by-case basis.

EPWA will provide administrative support to the WIC Review Working Group.

Consultation has concluded on Initiatives 1 and 2 as outlined here.

Consultation on Initiatives 4 and 5 will re-commence in due course.

Relevant documents including documents relating to public consultation are published on the WIC Review page.

At the 24 July 2025 MAC meeting, the MAC supported engaging the WIC Review Working Group to assist with the Coordinator’s review of the Benchmark Technologies used to set the Benchmark Reserve Capacity Price in the Reserve Capacity Mechanism. The meeting papers and the minutes from the relevant discussions can be found here.
