Judgment handed down on regulated electricity prices in Queensland

Origin Energy Limited (Origin) today noted the outcome of the judicial review by Queensland's Supreme Court in respect of the Queensland Competition Authority's (QCA) regulated retail electricity prices for the 2012-13 financial year.

The Supreme Court upheld the QCA's process for setting prices so no change to the 2012-13 prices will follow. As this was not a merits review, the judgment did not address whether the method used by the QCA to set prices was correct or appropriate.

Origin initiated a judicial review of the QCA's administrative decision as it believed that the QCA failed to take into account the actual costs of producing and supplying electricity, limiting Origin's ability to recover its wholesale costs.

Origin's profit guidance issued to the market on 8 November 2012 had assumed that there would be no change to the QCA's 2012-13 regulated prices.

Origin Managing Director Grant King said, "Origin is determined to seek a transparent framework for setting electricity tariffs with the goal of promoting efficient and competitive energy markets in all states, including Queensland. Those prices should reflect the actual cost of producing and supplying electricity to customers.

"Origin believes that the existing regulatory framework risks the long-term viability and competitiveness of Queensland's electricity sector and will ultimately lessen competition for consumers and stifle future investment in electricity generation.

"Today's outcome brings into greater focus the importance of progress by the Council Of Australian Governments (COAG) on energy market reform.

"We look forward to working with the QCA and the Australian Energy Market Commission which has been tasked by COAG to develop a consistent methodology for regulated retail prices, in particular the wholesale cost of energy. This should be an interim step towards COAG's stated aim of deregulated energy pricing.

"Origin will work with all levels of government to support a sustainable energy market - one which is structured to support investment and ensure a secure, reliable and affordable energy supply well into the future," Mr King said.

Origin will not be appealing today's Supreme Court judgment.
