The present inventive subject matter is thus drawn to a hybrid ultra reliable power generating system for supplying continuous reliable power at remote locations comprising: a primary power unit producing electric power that is supplied to a load. And a secondary power unit in the form of a closed cycle vapor turbine (CCVT) system that is capable of producing 100% of the electric power that is produced by the primary power unit and which is heated in hot standby by rejected heat of the primary power unit, wherein the vaporizer of the CCVT is maintained during hot standby at a temperature above its nominal operating temperature and the vapor turbine of the CCVT is preferable maintained at idle during hot standby at a rotating speed.Preferably, the CCVT includes a burner that combusts the same fuel as the primary power unit and supplies sufficient heat so that the CCVT produces 100% of power produced by the primary unit to the load once the primary power units stops operation.
