Electricity outages are bad for sure but even worse is if your not on a well & the village govt water goes out.
We have had it go for days sometimes & when it comes back man it is dirty for a few hours or more
We have lived years in Thailand & left & years later gone back...all the same

Meaning there is a minimum at most banks (usually only 1500-2k baht) so you are not charged a monthly fee.
If too small your account will eventually zero out
