The ERA conducts periodic reviews to ensure aspects of the WEM are functioning as intended.
Every two years, we review the operation of the regulatory scheme designed to manage the merger of the former State-owned generator Verve Energy with retailer Synergy. We prepare a report for the Minister for Energy that assesses the effectiveness of the scheme and make any recommendations for improvement.
We also review, every three years, the so-called "constraint equations" developed by the Australian Energy Market Operator (AEMO). Constraint equations are mathematical representations of any network limits in place that may effect the dispatch of electricity. As part of this review, we also consider the "limit advice" provided by Western Power to AEMO.
