Narrative:
Lost 1 engine idg (generator) prior to entering nat tracks. Checked with dispatch and maintenance and determined it was safe to proceed with APU operating normally. Just past 30W, lost other engine idg (generator). After contacting dispatch and maintenance, we determined it was the safest course of action to divert to bikf (our nearest ETOPS altitude). We departed the organized tracks in accordance with standard contingency procedures. Upon contact with icelandic oceanic, we were given a new clearance to bikf. We landed without incident. We declared an emergency upon departing the track, but cancelled the emergency with icelandic oceanic when established with them. There were no human factors which were involved in the event.
