The SA museum, a government site that could soon be supplied with clean energy.

The South Australian government is asking the energy industry to submit proposals to supply up to 100 per cent of government electricity requirements with low-carbon power.

The Low Carbon Electricity Supply and Services Expression of Interest seeks to procure up to 481 gigawatt hours of electricity a year to service government sites, and could include wind, solar PV, solar thermal, batteries, “efficient gas”, hydrostorage or hybrid proposals.

Premier Jay Weatherill said the tender was part of a commitment to make Adelaide the world’s first carbon neutral city.

“We are determined to make Adelaide a showcase city for low-carbon and clean technologies, to attract investment, drive innovation and create new jobs,” he said.

Indeed, South Australia has put itself at the forefront of clean tech innovation, with generous incentives for solar and battery storage, the prioritising of active transport and engaging in driverless car testing.

“We have created thousands of jobs and already generated $6.6 billion of investment in renewable energy, of which 40 per cent is located in regional South Australia,” Mr Weatherill said.

The EOI process marks a new approach for the government, which has until now purchased standard grid electricity from a retailer. The current agreements expire in late 2016 for the small government sites and 2017 for large government sites.

“This EOI process is an example of how the state government is helping facilitate a responsible, efficient and cost-effective transition towards to a lower emission future,” Treasurer Tom Koutsantonis said.

He said the proposals would be required not to negatively affect energy security, reliability or wholesale prices in the national electricity market.

“We will also encourage partnerships with South Australian companies.”
