Everything in that fuel mix is grid scale on the transmission network, not the distribution system that residential batteries are on. Looking at the records[0] page, maximum battery charging is approaching 4.5 GW in CAISO, so they're really trucking along in adding them to the grid. Wouldn't be surprised if they get passed by ERCOT over the next couple of years though, just tremendously easier to interconnect and build a facility in Texas.

I work for a company, that is implementing MWh storage on the grid, we have two very large scale storage projects set to interconnect in Southern California in the coming days.

There are more in the pipeline.

Grid scale battery storage is arriving, and I am thrilled to see it.

The new NEM 3.0 deal makes having a battery pretty much a necessity.
