The Anderson localization of electron states in random potential fields is one of the most fundamental problems that arise in number of physical phenomena . It is well known that in 1D and 2D systems with non-correlated, macroscopically homogeneous random potential distributions, all states are exponentially localized. In this paper we show that introduction of short-range correlations in random metal-dielectric composites results in delocalization of the surface plasmon states. We study in detail important statistical properties, such as the density of states, localization length, and the level spacing in percolation composites.
