The liberalization of public service’s market in Europe in now widely diffused.
During the last years, the European Commission has adopted several directives aimed to liberalize (and in some case privatize) different sectors such as electricity and gas. State members have implemented those directives at national level in different ways related to different specificities (economics, socials, cultural) of each sector. In this perspective, local public firms have defined their own reorganization’s strategies
of the supply side management to maximize the efficiency and minimize costs in order to compete with private firms, nationals and strangers. The mix of all those factors determines that actually, for local public services, we don’t have national supply models but service’s (gas, electricity, water, etc.) supply models.
