A Tesla Megapack caught fire at the Victorian Big Battery facility in Australia

A 13-tonne Tesla Megapack caught fire on Friday morning at a battery storage facility in south-east Australia. The blaze occurred during testing at 10 -10.15am local time, according to Victorian Big Battery. The regional fire service said a specialist fire crew had been dispatched to the site in Geelong, Victoria. Firefighters were using a hazmat appliance designed for hazardous chemical spills and specialist drones to conduct atmospheric monitoring, according to Fire Rescue Victoria.

The site was evacuated and there were no injuries, Victorian Big Battery said in a statement. It added that the site had been disconnected from the power grid and that there will be no impact to the electric supply. French energy company Neoen, which operates the facility, and contractor Tesla are working with emergency services to manage the situation.

As a result of the fire, a warning for toxic smoke has been issued in the nearby Batesford, Bell Post Hill, Lovely Banks and Moorabool areas, reports The Sydney Morning Herald. Residents were warned to move indoors, close windows, vents and fireplace flues and bring their pets inside.

The Victorian Big Battery site, a 300 MW/450 MWh battery storage facility, is viewed as key to the Victorian government's 50 percent renewable energy target by 2030. It follows the success of Neoen and Tesla's 100 MW/129 MWh battery farm in Hornsdale in South Australia, which was completed ahead of schedule in just 100 days and has resulted in multi-million dollar savings for market players and consumers. Both sites essentially provide a regional power backup for when renewable energy is not available, effectively filling the gap when the sun isn't shining and the wind isn't blowing.

In February, Neoen announced that the Victorian Big Battery would utliize Tesla's megapacks utility-sized batteries produced at the company's Gigafactory and Autobidder software to sell power to the grid. Victorian Big Battery has a contract with the Australian Energy Market Operator (AEMO). As part of the pact, the site will provide energy stability by unlocking an additional 250 MW of peak capacity on the existing Victoria to New South Wales Interconnector over the next decade of Australian summers.
