Narrative:
In cruise at FL370; [we] received an aural caution; 'hydraulic 3 lo press' and 'ib ground splrs' EICAS cautions. Followed sops and QRH procedures. During the QRH; [we] received EICAS status messages regarding dc (direct current) electrical system failures. The aircraft APU was MEL inoperative prior to departure. Company sops require two operative generators at all times. Flight crew determined the right engine generator was tripped off; and therefore we [informed ATC of our predicament]; we were left with just the left engine generator operating. Landed at [our destination] without issue until just short of parking at the gate; at which point we lost all electrical power. In result; we shut both engines down and had ramp [crew] tug us into the gate.
