Perl's /i runtime flag does not apply exactly to your situation, but it is a good idea to imitate its file renaming etc.

You can test for all the elements of the array at once. 

my $rprow = join '|', @remove_power_list;
$rprow = qr/(?:$rprow)/;

Use $rprow as before, but the loop on @remove_power_list is no longer needed.
