N2 - In this paper the topological behavior of the Italian electric power network is evaluated. The power system is modeled as a network G of nodes interconnected by links. Its vulnerability is evaluated through the use of some "classical" and recent metrics developed in the literature. These assessments allow managers and policy-makers aim to minimize the vulnerability of such systems to external events such as natural disasters or man-made actions by identifying vulnerable and weak points. The analysis of the network reveals that some metrics (e.g., those related to Basic Connectivity, Spectral Measurements or Spectral Scaling Method) must be considered from a qualitatively point of view. Indeed their numerical values suggest that the network under study could be decoupled in an "easy way". Only Importance and Community metrics allow assessing the reduction of the network vulnerability, for example, by adding new links.
