Despite a boost from wind energy, which increased its share of large-scale renewables certificates by 8 per cent, to 64 per cent, since 2013, uncertainty over the RET and lower hydro output meant that overall certificate creation likely fell 3 per cent over all in 2014.

The Renewable Energy Target (RET) is the primary support mechanism for renewable power generation in Australia and supported more than 331 renewable power stations in 2014. Green Energy Markets has analysed the creation of Large-scale Generation Certificates (LGCs) under the RET based on data available from the REC-Registry as at 22 May 2015. Wind was the leading renewable fuel creating LGCs and accounted for 64 per cent of certificates. Wind LGCs increased by 8 per cent from 2013 levels.

The number of LGCs produced by hydro projects fell by 39 per cent as generation levels returned to more normal levels after a surge in generation in 2013. The Gordon and Poatina hydro power stations in Tasmania, which are baseline generators, still produced enough LGCs to be in the top 5 largest creators. Of the 23 power stations producing more than 200,000 LGCs, 16 were wind farms (Table 1).

The Poatina and Gordon hydro power stations are baseline generators that were in operation on 1 January 1997. Pre-existing power stations are able to produce LGCs to the extent that their power generation is above their 1997 baseline. Both Gordon and Poatina considerably exceeded their 1997 baselines and will produce significant quantities of LGCs for generation in 2014. Power stations have until 31 December 2015 to produce LGCs for 2014 generation and we expect that more LGCs are still be created for these power stations. Based on an assessment of their electricity generation for 2014 we have estimated the likely level of LGCs for 2014.

In total, 14.6 million LGCs were created for electricity generated in 2014 (as at 22 May 2015). We estimate that there are still 1.1 million LGCs yet to be created for 2014 generation, largely from wind and baseline hydro generators (refer to Table 2). We estimate that a total of 15.7 million LGCs will eventually be created by power stations for 2014 generation, a 3 per cent decrease on 2013 levels.

A total of 46 new renewable power stations were accredited in 2014 and 30 of these produced LGCs for the first time in 2014.

    Interesting. I see that the total for Snowtown (which is effectively one wind farm – I would challenge an outsider to point out where one part finishes and another part starts) in 2014 is 1,027,000 LGCs – well ahead of Macarthur, which is slightly larger in terms of installed capacity.

    Also, there are four sections to the Hallett wind farm. The three listed: North Brown Hill, Hallett [#1 = Brown Hill Range WF] and Hallett Hill [Hallett #2] add up to 908,000 LGCs. The forth stage, Bluff Range is smaller than these, so that would be why it is not listed on this page, I figure would have generated around 158,000 LGCs. So the total for the Hallett group is around 1,066,000, even more than Snowtown.

    So, as a resident of Mid North SA, I claim that we have the two most productive wind farms in Australia.
