HORNSDALE: One year after the state of South Australia suffered a major blackout, the clock has started ticking for Tesla Inc to finish building the world's biggest battery to help keep the lights on in Australia's most wind-dependent state.
Tesla won a bid in July to build a 129 megawatt hour (MWh) battery and the state is counting on it to be ready by the start of the southern summer in December when electricity demand begins to peak.
