The public utility system presents complicated challenges for public policy. In many respects these challenges are similar to those in other network industries in providing a balance between regulation and markets, public investment and private risk taking, coordination and competition. As with other such industries, naturally monopoly elements interact with potentially competitive services, as electricity, gas and communication have some unusual features that defy simple analogy to other network industries. This paper is dedicated to the competition problems of these natural monopolies. It analyses how to organize and price access to and use of the competitive network. After presenting the technical and institutional features of the utility industry, the paper develops a normative approach to first-best and second-best pricing by means of new industrial organization. Then the exercise of market power at some nodes and its consequences for the transport system operator are examined. The remaining part is more policy oriented, describing and analyzing the practical solutions implemented in Japan, the EU and the US. The paper concludes with some remarks about the enforcement of antitrust rules in public utilities.
