So not only do you need to plan for the down time you need to consider the recovery time of your system. Lead based systems will take many times the run time to recharge and may not be ready for the next outage. Thus LiFePo4 batteries are the way to go, we can recharge at more than our discharge rate.
Not to mention the energy density and weight ratio of Lead Acid vs. Li-Ion. Li-Ion is pricier, sure, but less operationally expensive in the long term.
It is a bit late to be worrying about rolling blackouts this winter as the threat has reduced and by the time a solution is deployed at scale it will be spring or summer.
Given that there is a general global energy crunch, and that Li-Ion prices have slowed in their decline since Covid, one might do well to take the opportunity of reduced local demand to shore up energy security, before it becomes a scramble.
