An Expanded Renewable Energy Target was passed by the Australian Parliament on 20 August 2009, to ensure that renewable energy obtains a 20% share of electricity supply in Australia by 2020.
In 2011 the 'expanded MRET' was split into two schemes: a 41,000 GWh Large-scale Renewable Energy Target (LRET) for utility-scale renewable generators, and an uncapped Small-scale Renewable Energy Scheme for small household and commercial-scale generators.
