South Australia is poised to reap huge benefits in investment and jobs by increasing its renewable energy target to 50 per cent by 2025, the clean energy industry says.

"By boosting the target, South Australia is demonstrating commitment to attracting investment and jobs to its rural and regional communities," Clean Energy Council Policy Director Russell Marsh said.

"The state is showing that it's keen to win the race to attract the biggest slice of the national Renewable Energy Target's (RET's) benefits.

"With its plentiful renewable resources including sun, wind and geothermal, South Australia is well-placed to attract a range of large-scale projects - along with billions of dollars of investment and thousands of jobs - as a result of lifting its renewable energy target.

"However, none of this will be possible if the national RET is slashed as recommended by the Federal Government's Warburton Review of the policy.

"Nevertheless, it is heartening to see the South Australian Government taking the initiative to provide policy settings to encourage renewable energy investors to back projects in the state."

Mr Marsh said modelling on the national RET had shown that, if retained in its current form, the average household power bill could be more than $50 lower in 2020 than if the RET was reduced.

"More renewables means less reliance on gas-fired power, which is becoming increasingly expensive," Mr Marsh said.
