Do generators earn adequate revenue?

Electricity markets are always evolving to address new and emerging issues. The Wholesale Electricity Market (WEM) has seen its share of reforms and changes. Together they can have a substantial impact on generators, so to better understand the implications the Australian Energy Council (AEC) engaged Marsden Jacobs Associates (MJA). MJA’s review is pertinent across Australia and here we look at the key findings and consider whether generators in the WEM receive adequate revenue to support the dramatic transition underway.
