    Somewhat lost in the noise of the California wildfires is the Moss Landing fire that destroyed the Vistra Phase 1 system. It was the largest BESS on earth.

    LG Energy Solution's New TR1300 Operational At World's Largest Utility-Scale Battery Energy Storage Project https://www.prnewswire.com/news-releases/lg-energy-solutions-new-tr1300-operational-at-worlds-largest-utility-scale-battery-energy-storage-project-301313879.html

    That's what bothers me. Not that it didn't meet standards, but that it did meet them.

    and once again it is difficult to know what type of batteries specifically those batteries were beyond generic names that do not mean anything in particular such as "Li-ion"

    typical of the world in which we have become (1991-) accustomed to living: smoke and misinformation everywhere, tons of noise wrapped in tons and tons and tons of silence, silence, silence because let's not forget that the main function of the media is that the reader does not find out what is not published

    @CarlosK2 They use the LGchem JH4 pouch cells. Chemistry is proprietary. But LG's safety data sheet is, um, a curious read. Since the cell is an "article" and not a "substance", there isn't a Material Safety Data Sheet, just a Safety Data Sheet.
    https://www.mvcommission.org/sites/default/files/docs/LGCHEM JH4 Lithium-Ion Battery Cell MSDS.PDF

    The spec sheet seems to indicate max charge/discharge rates of about 1/2 rated capacity, so C 0.5 .

    An earlier incident at the facility is interesting - A battery is only as good as its control system https://www.pv-magazine.com/2022/02/03/a-battery-is-only-as-good-as-its-control-system/

    TLDR - A thermal runaway system was triggered; and failed fluid couplers sprayed water all over the place. Basically, they blew a coolant hose and soaked a bunch of batteries. Initially, there wasn't really a problem (a software glitch and a failed fan bearing started it all), but after the water sprayed the batteries there was. About 7% of the batteries had to be replaced. There is no record of the entire system being pressure tested, like you do on a house.
