In this study, we examine the quantization of Hall conductance in an infinite plane geometry. We consider a charge-conserving system with a pure, gapped infinite-volume ground state. While Hall conductance is well-defined in this scenario, there is no existing proof of its quantization. Assuming that the conditions necessary to construct the braided $C^*$-tensor category which describes anyonic excitations are satisfied, we demonstrate that the Hall conductance is rational under the assumption that the tensor category is finite.
