GEM: Large scale solar generation grows 300% in 2018, renewables pass 20% share
The contribution of solar PV to Australia’s electricity generation mix hit record new highs in 2018, in new figures published today by Green Energy Markets. Last year rooftop PV generation from new arrays was 86% higher than in the previous three years and utility scale solar increased 300% – passing the 1,000 GWh milestone for the first time.
Green Energy Markets (GEM) has charted the growing contribution of solar to Australia’s fleet of electricity generators in 2018, “with a far bigger impact to be seen this year,” says GEM’s Director of Analysis and Advisory Tristan Edis. The analysis was released today in GEM’s Renewable Energy Index report for December 2018.
The share of all renewables also had a banner year in 2018, contributing 21.3% of Australia’s electricity – the first time the 20% milestone had been reached in four decades. For the month of December, renewable share came in slightly higher at 23.2%.
“For wind the 26% jump in generation this year came after almost no growth in 2017,” writes Edis in the latest Renewable Energy Index report. “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 solar PV and wind, hydro also had an “up year” notes Edis, although its contribution is likely to fall in 2019 as more solar and wind comes online.
On the flipside, the GEM analysis notes that while the renewable generation gains were made at the expense on 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 (NEM) fell 26% in 2018, solar and wind grew by 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 current renewables boom in 2018.
In December, the Renewable Energy Index finds, over 3.2 GW of large scale solar projects are currently under construction – of a total of close to 7.15 GW. Big solar project construction is employing close to 7,700 people.
Turning to the rooftop, GEM finds that 22,010 PV systems were installed in December 2018. New South Wales and the Australian Capital Territory (combined) was 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).
