We present results of the electronic structure study for the solid solution (Fe_{1-x}Ni_{x})_{2}P (space group P6̅2m). The samples were synthesized for x=0.0 up to 0.15. From the electrical conductivity measurements on these materials, it was verified that resistivity increases with increasing temperature up to the Curie point T_{C} and changes the slope at T_{C} decreasing when temperature is raised above T_{C}. To get insight into the possible origin of such observations, we carried out the Korringa-Kohn-Rostoker-coherent potential approximation electronic structure calculations for (Fe_{1-x}Ni_{x})_{2}P in the range of concentration x=0.0 up to 1.0. It was found that alloying with Ni in Fe_{2} P causes vanishing of spin band splitting and non-rigid band behaving of electronic valence states near the Fermi level. The polarization factor for electrons at E_{F} changes in (Fe_{1-x}Ni_{x})_{2}P with increasing x, and interestingly, it reaches maximum at x=0.1, closely to the concentration (x=0.08), when the largest value of T_{C} and a kink in temperature dependent resistivity were detected.
