In this paper we discuss the European regulation policy regarding vertical separation in communications and electricity industries. In the electricity sector the discussion concerns ownership unbundling while in communications the recent regulatory debate is about functional separation. We conclude that for electricity, ownership unbundling seems to be the best option to achieve competition in wholesale markets although there is still some risks concerning investment. Instead, for the communication sector the regulatory options are deeply dependent on the intensity of network competition between operators that combine different technological platforms. Technology also seems to be a key driver for diverse regulatory approaches concerning the unbundling requirement.
