The restructuring of many national and state electricity industries over the last two decades has created new sets of laws and regulations, market design and participants. Along with those changes, industry risks have also been transformed significantly. Prior to restructuring, government-owned or carefully regulated monopoly private utilities would manage most of these industry risks. With restructuring, however, both the government, through their market regulators, and industry participants need to manage a range of previous,, yet also now new, risks. While the government???s risk management strategy is focused on the industry as a whole, participants are naturally more concerned with their individual risks. The Australian National Electricity Market (NEM) is one of the many electricity markets that were formed through the restructuring process underway worldwide. It created a number of new types of market participants facing different sets of risks. The main objective of this thesis is to examine the management of market risk by these different NEM participants. The methodology used in the thesis involves developing a fundamental understanding of electricity restructuring, the NEM and the various risks faced by the different NEM participants. Data on NEM spot prices, ancillary costs and forward prices are analysed to gain a better understanding of its relationship with market activities. Different risk management strategies, both proactive and reactive, that can be taken by the participants are discussed This thesis has highlighted some of the complexities involved in managing risks in a restructured electricity industry. Risks are never static and changes in market conditions alter the risk exposure of the participants. Therefore, participants will need to constantly monitor their risk exposure and update their risk management strategies. The Cash-Flow-at-Risk methodology is introduced as a possible tool to measure risk and analyse risk management options for different NEM participants.
