ion battery Tesla heading down under to build world's largest lithium-ion battery

Sydney, Australia-
Tesla announced on Friday that it will produce the world's largest lithium.
Ion batteries in southern Australia are part of an energy crisis that has caused continued power outages throughout the region.
Tesla will work with the French renewable energy company Neoen to build 100-
At megawatt battery farm in South Australia, Tesla CEO Elon Musk promised to deliver the system within 100 days of signing the contract, otherwise it would be free.
The billionaire entrepreneur was 100 at first.
He and the South Australian government confirmed on Friday that the deadline was part of their official agreement.
"This system will be three times more powerful than any system on Earth," Musk told reporters in Adelaide . ".
"This is not a small attempt at the border --
It's like three times further than anyone before.
South Australia, which relies heavily on solar and wind energy-
Since the state suffered a power outage in a storm last year, power generation has been scrambling to find a way to support its fragile grid.
Further power outages have plagued the state in the coming months.
The battery farm is part of a plan announced by South Australian Prime Minister Jay wesleer for a $0. 55 billion ($0. 42 billion) plan designed to make the state independent of the national grid.
Australian Energy Market operators managing the State Grid warned of a possible shortage of natural gas
By late next year, electricity will be available in southeast Australia.
As Australia is expected to soon replace Qatar as the world's largest exporter of liquefied natural gas, the shortage is imminent.
Australia is also a major exporter of coal, with most of the electricity generated in Australia.
South Australian batteries will store energy from the Hornsdale wind farm near Jamestown, located about 200 kilometers (120 miles) north of Adelaide.
Tesla says it will provide energy during peak hours to help maintain supplies in the state and power 30,000 households.
"When you have excess power and the cost is low, you can basically charge the battery pack and it will discharge when the production cost is high --
This reduces the average cost per hour for customers, "Musk said.
"This is a fundamental improvement in efficiency.
"The installation of the battery is expected to be completed by December.
The cost of the project has not yet been announced.
