Tesla Mega Pack in Moslanding, California

Victoria’s power, gas and pipeline safety regulators have granted Neoen and Tesla permission to “re-energize Victoria’s big batteries,” Neoen said in an email Monday.
Victorian Big Battery is owned and operated by Neoen and is one of the largest energy storage systems in the world. It aims to avoid power outages in the area and use power from renewable sources such as solar and wind power to power homes.
Based in Paris, Neoen developed the site in collaboration with partners such as Tesla Energy and AusNet and was built by UGL of the Cimic Group. Tesla has not disclosed the supplier of the project or the type of battery cell used in Megapacks, a lithium-ion battery-based storage system.
Tesla did not immediately respond to the request for comment.
A fire at the battery site in Giron, Victoria broke out on July 30th. Two Tesla megapacks burned in a 300 megawatt (450 megawatt hour) facility. No injuries have been reported, but the fire has issued toxic air warnings to the surrounding area.
Approximately 150 firefighters from the Country Fire Authority and the local Fire Rescue Victoria are called to fire, along with dozens of fire trucks, support vehicles and drones to monitor the temperature of the two affected Tesla Megapacks. It was done. The flame did not spread to any of the 210 other megapacks that make up the system.

By August 1, two days after the eruption, firefighters had stopped using water on site. The facility was declared under control on the afternoon of August 2.
The Country Fire Authority, WorkSafe Victoria, Energy Safe Victoria, and Environment Protection Authority then requested Neoen and Tesla to suspend some operations on Geelong to complete the parallel investigation.
Neoen expects the results of a completely independent study conducted by the Energy Safety Response Group and Fisher Engineering to be publicly available in November.
“The cause of the fire was identified as a simultaneous short circuit at two specific locations that was most likely caused by a leak of coolant outside the battery compartment,” said a spokesperson. “These happened when Megapack was offline in service mode to remove fault protection. This improbable sequence of events undetected the fault and caused a fire in the adjacent battery compartment. There was a possibility. “
Neoen also said that Tesla had taken “mitigation measures” after the company conducted a root cause analysis, adding that Tesla was implementing and monitoring changes to the Megapack firmware.
By the start of the Australian summer season in December, the system will need to be turned back on for testing from September 29th in preparation for commercial operation of a commercial battery.
Neoen and Tesla are under pressure to satisfy Australian regulators about collaborative work elsewhere. Last week, the Australian Energy Regulator (AER) told Neoen that another Tesla large battery it developed, the Hornsdale Power Reserve, did not provide the expected backup power during the four months of 2019 paid. I appealed.
