A Gen Drive Caution EICAS message resulted in the of the left engine generator. We accomplished the QRH procedure; declared an emergency and coordinated a return to our departure airport. We then started and brought on-line the APU Generator and full electrical power was restored. After conferring with Dispatch and Maintenance Control we elected to continue to our destination and canceled the emergency with ATC.
When the left generator drive malfunctioned the flight crew of a B757-200 disconnected the generator; started the APU; brought its generator on-line and proceeded to their destination.
