While conducting a ferry flight from ZZZ to ZZZ1 in Aircraft X; I requested priority for an electrical system failure.  The back-up system worked correctly and the weather was VMC.  No deviations from my flight plan were required.  All altitude and heading changes were coordinated with ZZZ1 approach.  ZZZ1 Approach expeditiously handed me off to ZZZ1 Tower after I had the field in sight.  I executed a visual straight-in to Runway XXR and stopped on the runway where I was met by the ZZZ1 emergency response team.  The Emergency Power Unit (EPU) activated hydrazine usage once the power was pulled back to idle during the landing phase. Hydrazine response was accomplished IAW ZZZ1 procedures.  No damage to the aircraft or government property occurred during this incident.
Pilot reported loss of electrical power while on approach to landing. Pilot continued to land while asking for priority handling.
