The present invention provides an integrated engine generator Rankine cycle power system which increases the efficiency of the use of its power output. The system comprises a closed Rankine cycle power generating unit through which working fluid flows and an engine generator, the closed Rankine cycle power generating unit including a waste heat boiler for vaporizing said working fluid by means of exhaust gases discharged from the engine generator, an expander in which the vaporized working fluid expands and performs work to drive a shaft for producing mechanical power, or an electric generator coupled thereto and adapted to produce electrical power, from both the engine generator and the expander, and an external lubrication system in fluid communication with the expander wherein one or more closed Rankine cycle power generating unit components are operationally connected to the electric generator.
