Cutting edge: Modelling dependence of price spikes in Australian electricity markets

The deregulation of Australian electricity markets has brought several challenges, including the possibility of price spikes, which expose market participants to significant risks. As Adebayo Aderounmu and Rodney Wolff outline, these spikes are hard to predict, and cannot be ignored

Price spikes are of particular importance due to their severe impacts on consumers, businesses and industry. They constitute a major source of risk to market participants – for example, electricity retailers with commitments to meet customers' daily electricity demands.
