The Finance Act 2008 included new measures relating to the production of electricity from RES, in two areas: a review of the green certificates system, applying to power plants = 1MW, and the introduction of feed-in tariffs for small renewable power plants. The revisions concerning green certificates are twofold. First, the incentive period is raised to 15 years. Second, the number of certificates issued varies depending on the type of renewable source, according to a coefficient multiplicative on energy produced. These coefficients, as amended by the Law No.99/2009 are as follows: - 1 for wind plants - 1.5 for offshore wind - 0.9 for geothermal - 1.8 for tidal and wave - 1 for hydroelectric - 1.3 for Biodegradable waste and biomass - 1.8 for Biomass and biogases obtained from agriculture, animal husbandry and forestry on a short supply-line basis - 0.8 for biogas. The Legilsative Decree No.28/2011, transposing the provisions of the European Directive No.28/2009 in Italy, announced that the Green Certificate Mechanism will be replaced by a Duch Auction System as of January 1st, 2015.
