The Greens have proposed to re-regulate the energy sector in a bid to reduce electricity bills for South Australians.
The proposal also aims to boost investment in renewables and establish a public energy provider.
SA Greens Senator Sarah Hanson-Young said the Greens have a plan to make renewable power affordable for everyone.
"The big energy companies have gotten away with price gouging for too long," Ms Hanson-Young said.
"Deregulation has been a failure, leading to power price rises that have done nothing but boost retailer profits."

Re-regulating the energy market would ensure a set price, matching the country's lowest cost.
The proposal suggests households would save $200 per year.
Under the plan, a $1.2 billion solar fund will provide grants to landlords to install solar panels on their properties.
Renters could save up to $890 per year on energy costs.
"People on low incomes and renters will benefit from lower power prices, including from the return on selling excess solar power to the grid," Ms Hanson-Young said.
The plan also looks to offer storage incentives for families to add battery storage to solar panels, under a $2.2 billion scheme.
"We want to turbocharge our renewable energy production with storage options for families and small businesses."
