Narrative:
Shortly after departing the right generator drive light illuminated with accompanying elec gen drive right EICAS message. Checklist was completed successfully disconnecting the right idg. Dispatch and maintenance control were contacted. Maintenance control confirmed the idg was disconnected and electrical system was fully powered using the APU generator. Maintenance control indicated there was no time limit for powering the right main bus with the APU. Dispatch calculated the extra fuel burn to run the APU. Weather was good along entire route and at destination. Dumping fuel; diverting; or continuing to destination were each discussed. Dispatch indicated there were no restrictions concerning ETOPS; rvsm; or mnps (minimum navigation performance specification). Decision was made to continue to destination while closely monitoring the APU and fuel score. Actual fuel burn was less than dispatch's calculated burn; so flight continued to our destination.
