SYDNEY, Australia—Tesla announced Jul 7 it will build the world’s largest lithium-ion battery in southern Australia, part of a bid to solve an energy crisis that has led to ongoing blackouts across the region.
Tesla will partner with French renewable energy company Neoen to build the 100-megawatt battery farm in South Australia state, with Tesla CEO Elon Musk promising to deliver the system within 100 days of signing the contract or it will be free. The billionaire entrepreneur originally made the 100-day pledge via Twitter in March, and he and South Australia’s government confirmed on Friday that the deadline was part of their official agreement.
“The system will be three times more powerful than any system on earth,” Musk told reporters in the state capital, Adelaide. “This is not like a minor foray into the frontier—this is like going three times further than anyone’s gone before.”
The battery farm is part of a AU$550 million ($420 million) plan announced in March by South Australia Premier Jay Weatherill to make the state independent of the nation’s power grid. The Australian Energy Market Operator, which manages the national grid, has warned of potential shortages of gas-fired electricity across southeast Australia by late next year. The shortage is looming as Australia is expected to soon overtake Qatar as the world’s biggest exporter of liquid natural gas. Australia is also a major exporter of coal, which fires much of its electricity generation.
The South Australia battery will store energy from Neoen’s Hornsdale Wind Farm near Jamestown, about 200 kilometres (120 miles) north of Adelaide. It will deliver energy during peak usage hours to help maintain the state’s supply, and could power 30,000 homes, Tesla said.
“You can essentially charge up the battery packs when you have excess power and where the cost is very low, and it discharges when the cost of production is high—this lowers the average cost per hour to the customer,” Musk said. “It’s a fundamental efficiency improvement.”
The installation of the battery is expected to be complete by December. The cost of the project has not been released.
The energy industry order comes as Tesla’s share price has floundered—largely as a result of bad news from its automotive segment.
Though it said it is ready to start production of its new Model 3 this week, it lowered year-end production expectations. Meanwhile, along with news of increased competition in the electric vehicle market, Tesla’s first-half deliveries of its Model S sedan and Model X SUVs also fell on the low end of its projections.
The company’s shares have plunged almost 15 per cent this week, translating to lost market value of US$8.7 billion.
