AEAS and RESS assessments for 2001–2010 compliance years were analysed by the former Office of Renewable Energy Regulator (ORER) and the 2011 compliance year by ORER and the current Clean Energy Regulator.

From 1 January 2011, the RET was split into the LRET and SRES. For liable entities this means that there are two targets to meet LRET and SRES. As a requirement of the split the:

• LRET annual interim targets were adjusted.¹ In 2011, the 2012 and 2013 targets were proportionately increased and 2016—2019 targets were proportionately decreased by the total increased am​ount. From 1 July 2012, the 2012—2020 targets were proportionately increased to support the introduction of waste coal mine gas as an eligible renewable energy source                    
• SRES annual interim targets are set and calculated on a yearly basis.²

2011 is the first assessed compliance year that represents the LRET and SRES. Graph 10 represents the number of STCs that have been accepted to discharge a mandatory liability for LRET under the Act for the given compliance year against the legislated target. Graph 11 represents the number of LGCs that have been accepted to discharge a mandatory liability for SRES under the Act for the given compliance year against the legislated target. For more information about the LRET and SRES targets see the RPP and STP pages.

AEAS and RESS liability and assessment

By 31 December 2012, a total of 56,950,592 LGCs were accepted for surrender against the 2001 to 2011 compliance periods and banked against future liabilities. LGCs which have been accepted for surrender against future liabilities are carried forward surplus LGCs. The carried forward surplus LGCs can be used by relevant liable entities to discharge their liability for future compliance periods.

For the 2011 compliance year, there were 86 liable entities that lodged an AEAS and RESS by 14 February 2012. This represents six liable entities with a total shortfall of 3,231 LGCs. One of which was required to pay the LGSC representing 2,537 LGCs.³

Overall, liable entities had a 99.97 per cent LGC compliance surrender rate.

For the 2011 compliance year, there was 214,208,303.1 MWh of relevant acquisitions of electricity and 27,187,757.4 MWh of partial exemptions had been reported resulting in a reduced relevant acquisition amount of 187,020,545.7 MWh. This resulted in a LGC liability of 10,510,555.⁴ For LGC surrender details see Table 9.
