Tesla Powerpacks in South Australia, which make up about half of the new Australian mega-battery.
Tesla Inc switched on the world's biggest lithium ion battery in time to feed South Australia's shaky power grid for the first day of summer.
The 129-megawatt-hour battery has garnered significant press for both its size and the nature by which it was acquired.
Weatherill came under fire past year after the entire state went black following a major storm, and raced to shore up the state's grid with a A$510 million ($385 million) plan, including ordering the big battery and installing diesel-fueled turbines. However, it had already begun dispatching some power into the state's power grid on the afternoon of November 31 as temperatures rose above 30-degrees.
The rest of the country will be looking at the Musk's battery and how in performs in South Australia with the country overall facing an energy crisis with a system that is "among the world's costliest and dirtiest", and "annoyingly unreliable", wrote Australian Financial Review in October.
Tesla's massive 100MW lithium-ion battery, the largest of its kind in the world and a project that won Elon Musk a $50 million bet, has gone live today in South Australia. South Australia has been suffering from energy issues, and even suffered a state-wide blackout last September.
Lithium-ion batteries have a greater charge cycle than conventional lead-acid batteries, and can respond within seconds.
The battery packs are expected to secure the region's electricity supply and allows for clean and affordable wind energy being dispatched to the grid.
Some have called the battery a "Hollywood solution", which likely stems from the flashy nature of the battery's creation in a country that does still rely partly on fossil fuels.
Highlighting industry hopes for the take-up of battery storage, Tesla CEO Elon Musk visited the site some 225 kms (141 miles) north of the state capital Adelaide in July, hailing the battery as "just the beginning".
