I’ll note that aggregate system cost still benefits significantly from including wind and other non-solar sources of energy; having a mix of different intermittent sources (and some firm generation such as geothermal) means less storage is needed.
How resilient are these batteries to flooding? I live on the Texas coast and have been through enough hurricanes that I know that flooding is just inevitable here. I’m not trying to play down the effectiveness of the technology, just wondering how they might fare compared to our terrible power systems in Texas?
You’d probably site them on higher ground outside of the flood plane. Add in flood walls, etc. if storm surge is a concern
