RE: Plant Powering
In the short term? None.
In the long term? Perhaps a little more energy cost maybe a percent. Possibly longer motor life due to possibly reduced current and hence slightly reduced winding temps. (Very slightly) Possibly longer motor life due to never under-voltaging your motors even in the plants darkest corners. Under voltage is the big motor killer not over voltage.
If you had a reversed voltage condition from your stated position I would say don't do it!!

RE: Plant Powering
Some common voltages for motors and systems in North America are.
Motor System
Rated Nominal
Voltage Voltage
115 120
230 240
460 480
575 600

RE: Plant Powering
i agree to itsmoked.
Motor will operate satisfactorily either short or long term provided that:
1.) motor operates within 10% voltage variation from rating.
2.) frequency is within 5% variation from rating.
Morever, 30% voltage variation is equivalent to single phase condition.
