South Australia unveils world's largest lithium-ion battery to feed its grid

Posted December 02, 2017

Weatherill came under fire a year ago 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. He told Reuters, "We think that's what's really going to accelerate the uptake of energy storage in Australia".

The battery, according to Hornsdale Power Reserve, takes up less than 2.5 acres of land and has the ability to power 30,000 homes for an hour during a blackout.

South Australia has announced the 100MW lithium-ion battery system has been connected to Neoen's Hornsdale wind farm in the region. The delivery is also ahead of Tesla CEO Elon Musk's self-imposed deadline of "100 days or it's free".

The manufacturer, Tesla, says the lithium-ion device made up of PowerWall 2 batteries is the "largest" by storage and "most powerful" of its type in the world.

South Australia, which relies heavily on solar and wind-generated energy, has been scrambling to find a way to bolster its fragile power grid since the entire state suffered a blackout during a storm previous year.

Jay Weatherill stated now, the South Australia is competing others in the rival of making renewable energy and it has made the history in the making.

Lithium-ion batteries have a greater charge cycle than conventional lead-acid batteries, and can respond within seconds. This is especially important given that this state gets a whopping 40 percent of its electricity from wind energy. "It can address those stability issues very quickly without needing to resort to using large power plants", said Praveen Kathpal, the vice president of AES Energy, who also bid for the battery contract.

Elon Musk built the battery after a dare from Aussie tech billionaire Mike Cannon-Brookes.

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.
