Just a week after completing construction of the world's largest lithium ion battery in Australia, Tesla has switched on its enormous device.
The 129-megawatt battery will be used to feed Australia's shaky power grid for the first day of summer, meeting a promise by Elon Musk, CEO of Tesla, to build it in 100 days or give it free.
Tesla hopes the battery will be the first step to Australia becoming a renewable energy powerhouse.

Just a week after completing construction of the world's largest lithium ion battery in Australia, Tesla has switched on its enormous device
Tesla has turned on the 100 megawatt lithium ion battery, which is more than three times larger than any existing power storage facility.
The battery was built at a wind farm operated by France's Neoen that is located about 225 km (141 miles) from the South Australian capital of Adelaide and will supply power to the lithium-ion storage cells.
Last year's state-wide blackout was blamed by opponents of renewable energy on the state's rush to embrace wind and solar, and fuelled a backlash that has split Australia's conservative federal government and led to renewed calls to support coal-fired power.
Speaking at the official launch at the Hornsdale wind farm, Premier Jay Weatherill said: 'South Australia is now leading the world in dispatchable renewable energy, delivered to homes and businesses 24/7.'
He added: 'This is history in the making.'
Tesla won a bid in July to build the battery for South Australia, the country's most wind power-dependent state.
Musk vowed to install it within 100 days of signing a grid connection agreement or give it to the state for free.
When the grid connection deal was signed on Sept 29, Tesla was already half way through installing the battery packs.
Finishing last week meant that the firm took just 55 days to complete the batteries.
The Tesla Powerpacks have been installed at a wind farm run by France's Neoen.
