Think more about centralized ops. Any individual store will of course notice their power has gone out.

But what do they do then? Call around to every nearby store asking if they still have power, and have space in cold storage? While those stores may well be calling yet other stores?

How does that work when there are 6 affected stores and 12 nearby ones that still have power? Maybe 3 of those have lots of cold storage, and another 4 have some but not lots free.

A centralized view could easily be worth $1k/month.

(and you are very fortunate if your utility reaches out to you in mass outages (>1000 customers), and especially if they do it via API your systems can act on)
