Australia: Large scale solar generation trebled in 2018 as renewables passed 20% share of national electricity output


From pv magazine Australia.

Green Energy Markets (GEM) has charted the growing contribution of solar to Australian electricity generation in 2018, “with a far bigger impact to be seen this year”, according to the research company’s director of analysis and advisory, Tristan Edis. The figures were released today as part of GEM’s Renewable Energy Index report for December.

The share of renewables also had a banner year in 2018, contributing 21.3% of Australia’s electricity – the first time the 20% mark had been reached in four decades. In December, renewables’ share came in slightly higher, at 23.2%.

“For wind, the 26% jump in generation this year came after almost no growth in 2017,” wrote Edis. “Rooftop solar has had more steady additions of generation but 2018 was exceptional, with the incremental new generation 86% greater than the average annual additions of 2015-2017. Yet it was large scale solar farms that really jumped out of the blocks in 2018, with generation leaping up by almost 300% on the prior year.”

Alongside PV and wind, hydro also had an “up year” noted Edis, although its contribution is likely to fall this year as more solar and wind comes online.

The GEM analysis noted, however, while renewable generation gains were made at the expense of brown coal and gas, “the large gains in black coal generation since the carbon price was abolished still remain”.

Gas generation on the National Electricity Market fell 26% in 2018 as solar and wind grew 35% and 26%, respectively.

While the growth in renewable generation was charted by GEM on a national basis, the increase was limited to the east coast, with Western Australia continuing to miss out on the renewables boom.

In December, the Renewable Energy Index found, more than 3.2 GW of large scale solar projects were under construction – for a total of close to 7.15 GW of such projects when wind is included. Utility-scale solar project construction is employing close to 7,700 people.

Turning to rooftops, GEM found 22,010 PV systems were installed in December. Combined figures for New South Wales and the Australian Capital Territory made that the leading region, with almost 5,700 systems; followed by Victoria, with 5,400; Queensland (5,300); Western Australia (3,150); South Australia (1,900); the Northern Territory (269); and Tasmania (262).
