An effective Hubbard model for one-particle d-like states and two-particle singlet states is derived in order to describe the low-energy electronic spectrum in ladder alpha-NaV2O5 compound. The energy shifts and the renormalized hopping parameters for the considered electronic states are calculated on the basis of the projection technique for the two-time matrix Greens function in terms of Hubbard operators.
