A 150-megawatt solar thermal power plant has been
secured for Port Augusta in South Australia, State Premier Jay
Weatherill has announced.
Construction of the $650 million plant will start in 2018.Aurora facts:
- 150-megawatt solar thermal power with eight hours of storage
- Plant will deliver 495 gigawatt hours of power annually, or 5 per cent of SA's energy needs
- Equivalent to powering more than 90,000 homes
- Located 30 kilometres north of Port Augusta
- Company says it is "completely emission free"
Mr Weatherill said the Aurora Solar Energy Project would be ready to go in 2020 and would supply 100 per cent of the State Government's needs.
The Government will pay a maximum of $78 per megawatt hour.
Mr Weatherill said the solar thermal plant was "the biggest of its kind in the world".
"Importantly, this project will deliver more than 700 jobs, with requirements for local workers," he said.
A shiver has
just gone up the coal generation industry's spine. Solar thermal just
won a competitive tender for base load generation in SA.
The Government contract with United States operator Solar Reserve will last for 20 years, and was the "lowest cost option" of shortlisted bids for the project.
The maximum Government load is 125MW, meaning the plant will be able to supply other customers.
"This, in addition to our state-owned gas plant, and the world's largest lithium ion battery, will help to make our energy grid more secure," Mr Weatherill said.

Project built on $110 million federal loan
Solar Reserve chief executive officer Kevin Smith toured the region in September last year, and said at the time it would need at least $100 million in federal grants or loans to proceed.

Senator Xenophon said the project would transform the energy market in SA and be a "flagship project for the entire nation".
"This will make a difference in the South Australia energy market. It will secure the grid and mean more baseload power than intermittent power," he said.
He said it would lead to more stable energy in the market, which would lead to lower power prices.
Port Augusta City Council Mayor Sam Johnson said the announcement left him with "a little tear in the eye".
"It's just an outstanding result and the amount of people that should be thanked, I mean, I could be here for hours thanking them all," he said.

The heat created is then used to generate steam.
Solar Reserve said the plant will be able to provide between eight and 10 hours of storage and had no requirement for gas or oil generated electricity as a backup.
It is expected to employ 50 full-time workers on an ongoing basis once it is operational.
The company said the power station will operate in a similar fashion to a coal or gas station, meaning many of the jobs would "require the same skill sets".
Mr Smith said he looked forward to supporting "federal and state renewable energy targets".
