The script file is /etc/rc.local but the systemd service name is
rc-local.

Since you seem to have the expected permissions for /dev/ttyUSB0 and
/dev/ttyUSB1 maybe you could just add gene and nut users to the dialout
group? adduser gene dialout and adduser nut dialout.

But if you really want to use rc.local then setting the group to nut
for the UPS line /dev/ttyUSB1 would work, so just

chgrp nut /dev/ttyUSB1

And then chgrp gene /dev/ttyUSB0

Hope it helps!
