The Victorian government will test market interest in new solar, wind and similar projects to supply enough renewable energy to power schools and hospitals.
In 2017, Victoria sought 650 megawatts of renewable energy through the state's renewable energy target auction.
The target was exceeded, delivering 928 MW of renewable energy-boosting supply.
The new market sounding process announced on Wednesday will test the capacity of industry to deliver at least a further 600 MW of renewable energy.
This would be enough to power every hospital and school in Victoria, Melbourne's train network and a range of other government infrastructure and services, the government said.
"Renewable energy is supporting thousands of jobs and local businesses across Victoria - and it will help drive our economic recovery from coronavirus," Energy Minister Lily D'Ambrosio said.
"It will deliver more reliable, affordable energy to households across Victoria."
The market sounding process will also explore the potential for electricity-reliant industries and businesses to buy renewable energy.
