I was International Relief Officer on scheduled rest break when notified to return to cockpit. Generator failure; checklist completed in accordance with flight manual. Flight unable to continue to destination due to additional APU fuel burn. Company decided to have us divert to [a nearby alternate] for multiple reasons including Maintenance; passenger accommodation; crew legality; and reserve crew availability. Captain decided to land overweight after considering all risk mitigations; threat evaluation; and crew agreed. Diversion and landing was completed without incident. Outstanding CRM; utilizing all crewmembers and outside resources.
Inflight loss of left engine generator over [international] airspace. Not able to continue to polar airspace due to loss of redundant equipment. APU was used. All power restored. Not enough extra fuel to power the APU for 12 more hours.
