Renewable power big Neoen plans to change its Tesla Megapacks back on on the Victorian Big Battery in Southeast Australia this week, after a fire in late July on the power storage web site.

Victoria’s security regulator for electrical energy, fuel and pipelines has granted Neoen and Tesla permission for “re-energisation testing of the Victorian Big Battery,” Neoen stated in an emailed assertion on Monday.

The Victorian Big Battery is owned and operated by Neoen and is without doubt one of the world’s largest power storage techniques. It’s meant to assist keep away from blackouts in the area and energy houses utilizing electrical energy from renewable energy sources like photo voltaic and wind.

Neoen, which is predicated in Paris, developed the location with companions together with Tesla Energy and AusNet with some building by Cimic Group’s UGL. Tesla has not disclosed its suppliers for the challenge or what kinds of battery cells it used in the Megapacks, that are lithium ion battery-based storage techniques.

Tesla didn’t instantly reply to a request for remark.

The fire on the battery web site in Geelong, Victoria, came about on July 30. Two Tesla Megapacks erupted into flames on the 300 megawatt (450 megawatt hours) facility. No accidents had been reported, however the fire triggered a poisonous air alert to surrounding neighborhoods.

About 150 fire fighters from the Country Fire Authority and native Fire Rescue Victoria had been known as on to combat the fire, together with dozens of fire vans and help automobiles and drones for monitoring temperatures of the 2 Tesla Megapacks effected. Flames didn’t unfold to any of the opposite Megapacks amongst 210 or in order that make up the system.

By Aug. 1, two days after the eruption, fire fighters stopped utilizing water on web site. The facility was declared beneath management on the afternoon of Aug 2.

The Country Fire Authority, WorkSafe Victoria, Energy Safe Victoria, and the Environment Protection Authority then required Neoen and Tesla to droop some operations in Geelong so they may full parallel investigations.

Next Steps

Neoen expects the outcomes of a full, unbiased investigation — performed by Energy Safety Response Group and Fisher Engineering — to be launched to the general public in November.

“The cause of the fire was identified as coinciding short circuits in two particular locations likely initiated by a coolant leak external to the battery compartment,” the spokesperson stated. “These occurred while the Megapack was off-line in a service mode that removed fault protections. Enabled by this unlikely sequence of events the fault was able to go undetected and initiate a fire in the adjacent battery compartment.”

Neoen additionally stated that Tesla has taken “mitigating actions” after the businesses performed a root trigger evaluation and added that Tesla is implementing modifications to its Megapack firmware and monitoring

The system must be switched back on for testing beginning Sept. 29, in preparation for industrial operation of the utility-scale battery by the beginning of Australia’s summer time season in December.

Neoen and Tesla are beneath strain to fulfill regulators in Australia for his or her joint work at a separate location. Last week, the Australian Energy Regulator (AER) sued Neoen saying one other Tesla big battery it developed, the Hornsdale Power Reserve, didn’t present backup energy as anticipated throughout a four-month interval in 2019 for which it had been paid.
