An incident which caused batteries to short has taken offline Phase II of Moss Landing Energy Storage Facility in Monterey County, California, the world’s biggest lithium-ion battery energy storage system (BESS) project.

Project owner Vistra Energy said yesterday that the 100MW/400MWh expansion phase of the facility now joins the 300MW/1,200MWh Phase I in being out of action, after the incident late on Sunday (13 February).

In what appears to be a repeat of what happened in September to Phase I, a sprinkler system released water onto battery racks.

......

The latest incident comes only a couple of weeks after integrated utility and power generation company Vistra issued a report into the situation at Phase I and said it was preparing to bring it back online soon. Vistra has now decided to pause those restart activities.

The recurrence of issues with the sprinkler system causing damage to the batteries is definitely concerning, especially considering the scale of the project.

That's back in 2022. The issues should be resolved by now.

It's understandable that Vistra Energy has decided to pause the restart activities until a thorough investigation is conducted.
