Direct current supply for electrolysis process in PT Indonesia Asahan Aluminium (Persero) achieves 193 kA. This is not optimal current as the transformer of Load Voltage Regulator (LVR) has power factor of 0.88 (lagging). This paper analyzes electrolysis current improvement by reducing harmonics through capacitor bank installation Software ETAP 12.0 is employed to model and analyze the system. By installing 90 MVAR capasitor bank for bus 33 kV in secondary side of LVRproduces 8% power factor correction and improves 13.5% of pot line current. Pot line current improvement enables aluminum production rate increased. Keywords: capasitor bank, electrolysis, power factor, LVR
