The document discusses recent changes to the competitive metering framework in Australia's National Electricity Market. It provides an overview of the market governance arrangements and the rationale for introducing a retailer-led competitive metering model. Key issues that will need to be considered in implementing the new framework include roles and responsibilities of retailers, distributors and other parties; consumer protection measures; transition issues; and specification of advanced metering functionality. The document also notes how the competitive metering reforms relate to the broader Power of Choice agenda and changes to distribution network pricing. Implementation of the new competitive metering framework will follow a timeline of submissions, draft and final determinations by the Australian Energy Market Commission over 2015.
