The Italian Council of State, by decision no. 2481 of May 26, 2017, declared the legitimacy of the resolution by which the Italian Authority for electricity, gas, water service (Aeegsi) determined the “Temporary price-related method” for the determination of tariffs for water services in the years 2012 and 2013. In particular, the recurrent associations considered that the tariff coverage concerning the costs related to the capital invested by the companies supplying the services coincided with the “capital invested remuneration” eliminated by art. 154 of Legislative Decree 152/06 with the abrogative referendum of 11 and 12 June 2011. The Council of State, confirming the first instance judgments of the T.a.r., clarifies that the tariff regulations introduced by the Aeegsi excludes the guarantee of a secure remuneration for inefficient managers and minimizes the burden on users. By contrast,, it allows efficient companies, with a sound economic management, capable to keep their costs under control, to make profit by recognizing financial costs, including those relating to equity capital, determined on the basis of a standard efficiency value. Consequently, the methodology adopted by the Aeegsi in resolution no. 585/2012 complies with the Referendum and the European principle of the “full cost recovery” of water services. The decision gives to the Author the opportunity to reflect on the theme of “Water” with particular reference to the profile of its management.
