In South Australia, California-based SolarReserve is building what will be the world’s largest thermal solar plant. The $650 million, 150 megawatt solar plant has received state development approval and construction on the project will begin in 2018. “It’s fantastic that SolarReserve has received development approval to move forward with this world-leading project that will deliver clean, dispatchable renewable energy to supply our electrified rail, hospitals and schools,” South Australia’s acting energy minister Chris Picton told the Sydney Morning Herald. When fully operational, the plant will provide electricity for 90,000 homes and generate 500 gigawatts of energy each year.

The South Australia solar thermal plant will feature a single tower that stands at the center of a vast field of solar mirrors, also known as heliostats. These mirrors reflect the sun’s rays onto the tower, which incorporates molten salt batteries to store the energy. This power can then be released as steam, which powers an electricity-generating turbine. When completed, the plant will mitigate the equivalent of 200,000 tons of carbon dioxide emissions annually.

The plant will be located roughly 30 kilometers (18 miles) north of Port Augusta in South Australia, a region which has generated international headlines for its energy developments. In collaboration with Tesla, South Australia now hosts the world’s largest single-unit battery, which is capable of providing power to 30,000 homes. “The state has taken a series of positive steps towards greater energy independence which are really starting to pay off. And it has already met its target of 50 per cent renewable energy almost a decade early,” said Natalie Collard, Clean Energy Council executive general manager, according to the Sydney Morning Herald. “South Australia is providing the rest of the country a glimpse of a renewable energy future. Our electricity system is rapidly moving towards one which will be smarter and cleaner, with a range of technologies providing high-tech, reliable, lower-cost power.”
