The Decree entered into force on 15 February 2004 and sets out in twenty articles a national framework for the promotion of renewable energy sources and particularly for their use in micro-generation plants. The decree adopts a definition of electricity produced from renewables consistent with article 2 of the EC Directive 2001/77/EC. The Decree sets a timetable for the periodic reporting, review and monitoring, by the Ministry of Economic Development, of progress towards the implementation of the objectives. In addition, the Decree introduces various measures, such as a simplified permit procedure to build power plants, an asking the Regulator to favour the grid connection process. To assess the exploitable energy potential from biomass, an ad-hoc experts committee has been created to help design appropriate legislation. The Decree provides also the adoption of legislation and criteria (minimum requirements, possibility to accumulate incentives, preferential tariffs, capacity targets, use of green certificates) for granting incentives to power produced from solar energy. The Decree includes specific provisions which favour biomass and hybrid plants (i.e., those producing part of their power from renewables) over fossil fuel plants in dispatching. A five-year programme agreement between the MSE and ENEA on RD&D measures to support renewables and energy efficiency has been established. Regional targets for renewable-based electricity are encouraged and regional governments can establish their own plans for renewables support. Specific articles address the issue of guarantee of origin for electricity produced from renewables, which can be requested for plants producing more than 100 MWh per year from GSE. Conditions under which the electricity produced can be sold in the power market or purchased by GSE are indicated. Specific rules are set for the streamlining of authorisation procedures for plants and infrastructure devoted to power production from renewables.
