GRUB can be told about an upcoming fsck and display a message inviting
you to choose to do it or not. So you get to know about it in advance;
which presumably you didn't know before.
You, as the person best placed, can decide whether the fsck can be
afforded based on the status of the power supply. The ability to
interupt the fsck after a power cut is of dubious value but, assuming
you are aware of your present power reserves and what is drawn from them
by an fsck, you could maybe uncross your fingers.
