The fluctuations of the net electric charge of hadrons, produced in ultrarelativistic heavy ion collisions are considered in the Monte Carlo model with string fusion. We demonstrate that the observed experimentally centrality dependence of the dynamical net charge fluctuation variable can be explained by formation in central AA collisions of the strings of higher string tension. We provide the predictions for net charge correlations in Pb-Pb collisions at LHC energy and discuss the applicability of the method at SPS and NICA energies.
