Abstract :
In the framework of national policies, which, since the end of the 1970s have had the target of making consumers rationally use natural sources, in particular energy, and in the pursuit of environmental goals, the Governments and the utilities have driven several DSM actions in many countries. The activities implemented by ENEL have included the analysis of the different components of the energy drain, from the primary sources to the final use in industry, agriculture, residential and commercial buildings. This is in order to improve the energy efficiency by new electrotechnologies and more effective appliances. Moreover ENEL has carried out commercial initiatives by specific contractual agreements based on the marginal costs of the electric service. The paper explains ENEL´s strategies and the actions implemented by the utility on DSM; the results in terms of energy efficiency, electric demand dynamics and of load curve changing are also explained. Finally the paper explores the DSM perspectives in the Italian future scenario, where energy companies will act in a more competitive market
