The report is intended to meet the needs of a wide audience, including government, industry and the broader community. It supplements the AER’s extensive technical and compliance reporting on the energy sector. The 2011 report consists of a market overview, supported by chapters on the electricity, gas and energy retail sectors. The report focuses on activity over the past 12 – 18 months in those jurisdictions and areas in which the AER has regulatory responsibilities. TheState of the energy market is an evolving project, and the AER will continue to review its approach. In the meantime, I hope this edition will provide a valuable resource for market participants, policy makers and the wider community. Andrew Reeves Chairman 1 market oVerVIeW Paul Rovere (Fairfax) For many years Australia enjoyed relatively stable the rate of return on network investment, to provide electricity prices. But this situation has changed certainty for investors and allow the regulatory approach markedly, with substantial price increases since 2007. to keep pace with changing financing practices. The increases are mostly attributable to rising charges The Australian Energy Market Commission (AEMC) for energy networks — the poles and wires, and gas is consulting on the Rule change proposals, and will pipelines that transport energy.

While this Rising network charges are being driven by a mix was a positive development, average spot prices are of factors that have increased the costs of building only a partial indicator of the energy costs that retailers and running electricity networks and gas pipelines. pay. Retailers and generators manage the risk of spot These factors include continued growth in peak energy price volatility by entering hedge contracts with each demand, stricter reliability and safety standards imposed other and through futures markets such as the Sydney by jurisdictional agencies, growth in customer numbers, Futures Exchange. the need to replace ageing equipment, and higher debt costs.

Strategic While this approach has successfully increased network bidding — rather than changes in the underlying investment, it restricts the regulator from making costs of meeting demand — is sometimes driving very holistic assessments of how much of that investment high or very negative prices. When spot prices do is efficient or necessary. This restriction has led to not reflect underlying costs, market participants rely consumers paying more than necessary for a safe and on futures markets more heavily to manage risk and reliable energy supply. secure future earnings.
