Elon Musk's renewable energy charge isn't letting up anytime soon.

Not content with planning to foster the mainstream take-up of electric cars, Elon Musk has announced Tesla will build the world's biggest battery in South Australia to store renewable energy.

After a competitive bidding process, Tesla was chosen to lead the charge and will provide a 100 MW/129 MWh powerpack system which is paired with a wind farm, working alongside renewable energy provider Neoen and the South Australian government.

The firm expects the project to be completed by December 2017, and when finished, will be the largest lithium-ion battery storage project in the world, providing "enough power for more than 30,000 homes", according to Tesla. It is expected that the battery will improve the security of electricity supplies across Australia, and is a key aspect of the government's energy plan drawn up after last year's mass blackout.

Back in March, the Tesla boss had pledged to deliver a battery system within 100 days of signing the contract, and if unsuccessful would deliver the system for free.

South Australia's Premier Jay Weatherill said on Twitter: "South Australia is already leading the nation. Today, we lead the world."

Earlier this week, Musk announced that Tesla's Model 3, billed as the firm's first mass market car, will start to be delivered at the end of the month. The company is hoping the vehicle will accelerate mass take-up of electric vehicles.
