Annual Wholesale Electricity Market Effectiveness Reports

Each year, the ERA provides a report of how the Wholesale Electricity Market performed to the Minister for Energy. The report is designed to highlight important events and trends during the year to assist in monitoring and facilitating market performance.

Part of our review is to seek feedback from stakeholders. Each year we release a discussion paper for the public to provide feedback. The feedback we receive is considered as we formulate our report which is provided to the Minister for Energy and made available on our website.

In addition to our annual reviews we undertake a triennial review to assess the extent to which the Wholesale Electricity Market objectives of the WEM are being achieved. Our last review was undertaken in 2014. These reports are combined with our annual review report. These reports are delivered to the Minister for Energy for tabling in Parliament. Once that occurs we make the report available on our website removing any commercially sensitive information.

The ERA has completed its review of the Wholesale Electricity Market for 2016/17.

We published the report on our website on 15 January 2018.
