I think I'm conflating two numbers, the 6% is probably year-round total contribution from solar, but there is 12 MW solar installed out of ~30-40 MW of demand (this is just a guess based on ~9000 households and businesses) so solar contribution is presumably much higher on sunny summer days, which as I understand from your thread, these primary control issues start to become significant.

@tetron Ah, 12 out of 40MW sounds way better! Yes, the problem with PV is that you need way more of their nominal power, because you rarely have their peak power, and when you have it, it's usually too much. This naturally leads to you wanting to keep that excess energy to cover for when you do not have enough. And, yes, batteries are great for that. They can gobble up excess power, and later discharge it, and switch between the two in milliseconds.
