This report reveals that the Australian renewable energy industry commenced construction on over 5000 MW of large-scale wind and solar farms in 2022 – the highest year for new renewable construction commitments on record.

Investors are also responding to the need for more energy storage, with 19 large-scale battery projects under construction, with combined capacity of those projects (1380 MW/2004 MWh) significantly higher than the previous year (921 MW/1169 MWh).

Renewable energy accounted for 35.9 per cent of Australia’s total electricity generation in 2022, up from 32.5 per cent in 2021. Australia has more than doubled the amount of renewable energy since 2017 when renewable energy accounted for just 16.9 per cent of generation.

Key findings:

• 2257 MW of new large-scale renewable generation capacity completed construction and was added to the grid across 20 projects.
• The rooftop solar sector added 2.7 GW of new capacity from 310,352 households and small businesses.
• 4.6 GW of onshore wind projects either commenced construction or were financially committed.
• 1380 MW/2004 MWh of large-scale batteries were under construction at the end of 2022, a significant increase in capacity compared to 2021: 921 MW/1169 MWh.
• Year-to-year investment in the clean energy industry for large-scale projects rose 17 per cent from 2021, at $6.2 billion in 2022.
• 28 renewable power purchase agreements (PPAs) were finalised in 2022, directly contracting around 1600 MW – the largest volume since the emergence of corporate PPAs in 2016.
