Again, this is quoting from the report I linked up-thread: https://emp.lbl.gov/hybrid. (Linked PDF with lots more detail: https://emp.lbl.gov/sites/default/files/hybrid_plant_trackin...)

> Data on plants under development from the interconnection queues of all seven ISOs/RTOs plus 35 individual utilities suggest that these hybridization trends are likely to continue. At the close of 2021, there were more than 670 GW of solar plants in the nation’s queues; 285 GW (~42%) of this capacity was proposed as a hybrid,

Perhaps I'm mis-interpreting this (not my field), and it's plausible I suppose that these projects won't get approved uniformly. I'd be happy to get more clarity on this if the report is actually saying something different. (I acknowledge my original phrasing could have been better, the way I wrote it suggests "solar that has just been built" vs. "solar that is currently planned to be built". But I don't think that's the source of your surprise, it's surprising because batteries are supposed to be uneconomical any time soon.)

Anyway, if I'm interpreting this correctly it seems like quite big news; I certainly shared your priors/skepticism on battery storage prior to stumbling across this report.

storage isn't measured in watts, which is a unit of power, it is measure watt-hours, witch are units of energy.
