A normalization procedure has been applied to improve the descriptive and predictive power of the enhanced generalized superfluid (EGS) model for the nuclear level density (NLD). In this procedure, the EGS model is normalized based on the experimental average level spacing at the neutron binding energy 
and the cumulative number of experimental discrete levels in the low-energy region N(E). The values of normalization parameters are determined by systematically analyzing a set of 288 nuclei from 
Mg to 
Cf, whose experimental and N(E) data are available. The systematical analysis permits to determine the values of the normalization parameters for any nucleus. The descriptive and predictive power of the normalized EGS (NEGS) model are demonstrated by making the comparison of the NEGS NLDs with the experimental NLD data of 70 nuclei obtained from the Oslo method. The results obtained show that the NEGS model describes reasonably well almost all the experimental NLDs and should be better used in the reaction codes than the conventional EGS, in particular for nuclei whose experimental NLDs are not available.
