In a speech in Adelaide, Frydenberg said renewables would play an increasing role in power generation over the next few years.

He said consumers would push changes in the electricity market through rooftop solar, batteries and electric vehicles as coal fired power continued to wind down.

“Already eight of our 12 most emissions intensive power stations have been retired,” he said.

“Indeed, around 20% of Australia’s coal fired power stations are scheduled to close by 2022.”

The Turnbull government has pledged to reduce emissions by 26-28% on 2005 levels by 2030.

Renewables will play an increasing role in meeting that target but Frydenberg said the transition needed to be planned to ensure reliability in the electricity grid.

The CSIRO roadmap will highlight areas of potential growth in the local clean energy sector and will map the development of new emissions reduction technologies.

It will also identify opportunities to be part of future global energy supply chains.

The roadmap will likely hold few surprises for coal miners, with most setting their sights on customers outside Australia.

For the wider industry, it could outline a path to bringing renewable energy onto more remote sites.

There are already 482 large-scale renewable power stations accredited under the Renewable Energy Target and that figure will need to double between now and 2020 to meet the government’s target.

Frydenberg also said gas would play an important role in the future energy market.
