The transformation of Australia’s electricity grid is accelerating. Australia is installing solar and
wind so fast that it is now leading the world in the per capita deployment rate for renewables, overtaking
Germany and the United Kingdom (see Figure 2).10
2018 was another record-breaking year for new Large-scale renewable energy power stations and
Small-scale solar PV installations for households and businesses. Total renewable capacity installed under
the Renewable Energy Target more than doubled from 2.2 gigawatts in 2017 to 5 gigawatts in 2018.
The year was characterised by a fundamental shift to solar for households, businesses and large
utility-scale power stations, with a notable increase in the mid-scale solar range of 15 kilowatts to 5
megawatts11 (see more about the shift to solar in Chapter 2 from page
Construction of new renewable capacity under the Large-scale Renewable Energy Target continued to
increase during the year, ahead of the trajectory required to meet the 2020 target. We expect current
levels of investment to remain in the near-term, as costs of renewables continue to fall and appetite for
power purchase agreements grow, with sufficient new generating capacity by the second half of 2019 to meet
the 2020 target.
Some 11.6 gigawatts of capacity has been firmly announced since 1 January 2016. Of this, more than 4.5
gigawatts are already accredited and generating, 5.4 gigawatts are under construction and 1.7 gigawatts are
subject to power purchase agreements with construction to begin in 2019. The split between Large-scale wind
and solar projects remained similar in 2018, with solar accounting for 50 per cent of the firmly announced
The firmly announced capacity in the pipeline of projects significantly exceeds the 6.4 gigawatts
required to meet the 2020 Large-scale Renewable Energy Target. This capacity will generate approximately
32,400 gigawatt hours of renewable energy electricity when commissioned.
2018 saw several record-breaking outcomes, including:
The generation capacity of the accredited and firmly announced projects will create enough Large-scale
generation certificates to exceed the target.
Generation from power stations increased in 2018 due to the large increase in the generation capacity of
power stations accredited throughout 2017 and 2018.
Investment by Australian households and businesses in Small-scale renewable energy systems continued to
grow in 2018, largely due to reduced technology costs, a competitive market and electricity costs.
The ongoing momentum in 2018 was characterised by the following outcomes:
The average size of Small-scale solar PV systems continued to increase in 2018, up by 11 per cent from
6.4 kilowatts in 2017 to 7.1 kilowatts in 2018.
Traditionally, most Small-scale solar PV systems have been installed in the residential sector. As
technology costs have fallen, uptake by businesses has increased and there is an increased focus on
residential rental markets and government housing.
The renewables roll out across the nation is delivering economic growth, especially in regional areas,
creating stronger local economies and localised job growth.
In 2018 a record $26 billion was invested in Large-scale renewables projects.13 This led to new employment opportunities with the creation of 13,000 jobs, a
large proportion in regional areas.14
2018 investment highlights include:
The strong growth in renewables in Australia is attracting international investors, further evidence
that the market is maturing. Of the current pipeline of projects, at least 5400 megawatts have secured
international equity or financing.
In addition to the support provided by the Renewable Energy Target, a range of other factors have driven
the uptake of renewables, including:
Innovation is also contributing to the sustainability and growth in renewables. New and emerging
technologies are offering potential to improve efficiencies, reduce costs and increase generation, while
pairing with energy storage can help to balance variable generation and deliver power when demand for
electricity is high.
Innovative use of technology also extends to reducing the impact of renewable energy power stations on
wildlife. For example, a novel aerial monitoring and detection technology is being trialled to prevent harm
The deployment of renewables is pivotal to Australia’s transition to a low carbon economy. The scale of
transition is unprecedented and the pace of change accelerating.
As the Australian Energy Market Operator’s Chief Executive Officer, Audrey Zibelman, stated, ‘There are
6.5 solar panels being installed on rooftops every minute in Australia. We are leading the world in terms
of implementation. We have to look at the future, we have no choice but to look at the transition that is
To accommodate the rapid penetration of variable renewables generation that is geographically dispersed,
parts of Australia’s grids need to be strengthened. New responses that offer flexibility to balance changes
in generation, demand and time of use are also needed (see Chapter 4 from page 34 for more on the
opportunities and challenges associated with the integration of more renewables).
Increased volumes of Large-scale renewable energy power stations and Small-scale solar PV also pose
challenges to our administration of the Renewable Energy Target. We are actively seeking ways to improve
efficiencies and effectively manage compliance risks that come with more renewables (see Chapter 5 for
information on major initiatives to strengthen the integrity of our schemes).
The Renewable Energy Target reduces Australia’s emissions by displacing coal and gas used for
electricity generation and heating with renewable sources such as solar, wind and hydro.
Australia has two targets to reduce greenhouse emissions under international agreements:
Data from the Australian Energy Market Operator’s final quarterly energy dynamics report for 2018
indicated that National Energy Market emissions were the ‘lowest on record’ and down 9 per cent on the same
quarter in 2017.17 Over the
decade 2008 to 2018, annual National Electricity Market emissions have reduced by 38 million metric tonnes
of carbon dioxide equivalent (Mt CO2-e), caused by lower emissions intensity (approximately
three-quarters of the reduction) and reduced consumption of grid electricity (the remaining
National Energy Market emissions intensity is now 15 per cent below the 2008 level, with wind and solar
continuing to displace gas and brown coal generation, and now starting to displace black coal
increase in renewables is a direct result of the Renewable Energy Target.
Reduced consumption of grid electricity is driven by energy efficiency and rooftop solar PV—as
households and businesses generate their own solar electricity they reduce the amount of electricity they
draw from the grid. In this way, the Small-scale Renewable Energy Scheme also contributes to the reduction
