Here's the quote from the municipal power CTO about why they we need batteries: "if we go above a certain threshold with solar, when we don't have enough load, current power power protection devices will not work correctly, that can lead to damage to the grid"
I don't know what threshold that becomes a problem but I found a chart that says the town gets about 6% of electricity from solar and had about 12 MW installed in 2022, with a strong political mandate to be carbon free by 2030.

@tetron Sorry, but I cannot decipher that statement. "Power protection device" is a rather generic term and I don't know what this refers to here. And 6% doesn't seem a lot to me, but then I don't know the other parameters of this grid. FWIW, as I wrote in my thread, you can always _curtail_ solar power to protect your grid. You throw away free energy by doing so, but safety has its costs.
