Narrative:
We arrived at the gateway a bit early and met the inbound crew. They briefed us on several mels and informed us that that they had had issues with the right generator inflight. The mechanic disconnected the generator and we departed with the right generator deferred. I had just finished upgrade training and had had a loss of two generators scenario on my line orientation experience (loe) so I was familiar with what to do if we lost a second power source. We talked about what we would do and monitored weather at enroute airports. As we received or initial descent clearance we got an APU fault EICAS message with the associated fault light. We ran the QRH procedure as we were descending. We were able to get the fault light to extinguish but the APU did not start. At this point we determined that a normal descent would take us to the approach that we had already briefed. We chose to continue instead of spiraling down to and briefing a new approach into an unfamiliar airport. We continued to an ILS at [the destination]. At about 16;000 feet the APU finally restarted and we had a second power source again. After it had been running a couple of minutes we chose to cancel the emergency and continued to an uneventful approach and landing on [the] runway.

Title: B757 flight crew reported temporary single generator event during approach.
Narrative: We arrived at the gateway a bit early and met the inbound crew. They briefed us on several MELs and informed us that that they had had issues with the right generator inflight. The mechanic disconnected the generator and we departed with the right generator deferred. I had just finished upgrade training and had had a loss of two generators scenario on my Line Orientation Experience (LOE) so I was familiar with what to do if we lost a second power source. We talked about what we would do and monitored weather at enroute airports. As we received or initial descent clearance we got an APU FAULT EICAS message with the associated FAULT light. We ran the QRH procedure as we were descending. We were able to get the FAULT light to extinguish but the APU did not start. At this point we determined that a normal descent would take us to the approach that we had already briefed. We chose to continue instead of spiraling down to and briefing a new approach into an unfamiliar airport. We continued to an ILS at [the Destination]. At about 16;000 feet the APU finally restarted and we had a second power source again.
