1. A power system comprising:
- a first prime mover configured to generate a drive force mechanically coupled to a first generator to produce electric power;
a second prime mover configured to generate a drive force mechanically coupled to a second generator to produce electric power;
an external load having a base power load and a variable power load;
a controller configured to control the operation of said prime movers to discharge power to said external load, wherein said controller controls said first prime mover to provide the majority of the base power load and controls said second prime mover to provide the majority of the variable power load.

Abstract
A power system generator set utilizing at least one engine capable of operating on one fuel source and another engine capable of operating on a different fuel source is provided. Specifically, a power system is provided for providing power to an external load having a base power load and a variable power load wherein the majority of the energy consumed by the external load is provided by an engine having a first fuel source and the majority of the variable power consumed by the external load is provided by an engine having a second fuel source.
