It's often said that a week is a long time in politics. The almost 100 weeks since the 'black system' in South Australia and the resulting political response can be considered an eternity. During this period, we have seen some of the most significant developments and interventions in the National Electricity Market (NEM),  since it's inception almost 20 years ago. This includes (but is not limited to) Government led interventions, such as the South Australian Energy Plan, Snowy 2.0 and the now mortally wounded National Energy Guarantee (NEG). Additionally, the Australian Energy Market Operator has also taken on a more proactive role with respect to planning and has shown a greater willingness to intervene in the operation of the market. This seminar will explore these interventions, the evolving political economy of the power system, a post-mortem of the NEG and the potential implications for the future and long-term sustainability of the National Electricity Market.
