It's nice to help this gentleman out with some tips, but let's keep it in perspective. If you were and officer in the Navy, then yes, you can be a supervisor or mid-manager with most utilities.
However, there is alot more to becoming a plant manager than some ring-tapping and being an engineer. There are many level 3 Engineers (civil, mechanical, design, and electrical) that make less money per year than RP supervisors. These engineers (and there is alot of them) will never be a middle manager, let alone a plant manager.
Good Luck.
