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.
As before, no one was harmed, but after Phase II’s early detection safety system kicked in, local fire crews were called to the scene, in line with protocols and out of what Vistra described in a brief statement as an abundance of caution.
