Confirming the battery in question is Li-Ion

=======================

Developer Terra-Gen will now investigate the cause of a fire at its Valley Center BESS in California, with public safety measures lifted and the incident considered “over”.
A battery storage unit in the Valley Center Energy Storage System caught fire at approximately 5.15 pm local time yesterday (18 September), Terra-Gen said in media statement provided toEnergy-Storage.news.
Fire and Sheriff’s departments were dispatched, roads were closed and an evacuation order for the surrounding 1/4 mile was issued, while a shelter in place for the 1/2 mile around the site was also issued, however these were only kept in place for at most four hours.
The facility’s design kept the incident contained and the measures were lifted by 9.15 pm the same evening, Terra-Gen said in a statement at 5.05 am local time (Pacific Daylight Time) today (19 September).
San Diego County Hazardous Materials team monitored the air and water around the site during the incident and found no hazardous conditions, the statement added, finishing:
“Now that the incident is over, Terra-Gen will investigate the cause of the fire with the support of
the Valley Center Fire Department.”
The project, near San Diego,was announced as online by Terra-Gen in March 2022and has an energy storage capacity of 140MW/560MWh.
It made headlines earlier this year when some 100 LG lithium-ion battery packs were stolen from late December 2022 through January 2023.Energy-Storage.newswas told by Terra-Gen in March, a few weeks after the incident, that these weredecommissioned, palletised and awaiting transportation to a recycling centre.
Asked why these were decommissioned, the spokesperson a week later said that a “a sensor system fault triggered the water-based protection systems resulting in the batteries in question to be taken out of service”.
Faulty sprinkler systems have also been described as the cause of several other notable fires at large-scale battery storage projects,including Moss Landing Energy Storage Facility, also in California.

The costs of fire suppression systems, cost of actual fire incidents, insurance costs, maintenance and monitoring equipment, then mix in community concern, and with Australia's generally hot and dry climate, Lithium batteries for large scale storage is just a bad idea and has to honestly be approaching the costs of vrfb at this point all things considered.

Now Vincent Algar is no longer at AVL, I wouldn't mind him being thrown a few dollars from within our industry to be right on top of these incidents and loudly spouting the benefits of vanadium batteries over lithium.
