Law 245/2007 (Finance Law 2008), implemented by Decree of 18 December 2008

The 2008 Finance Law includes new measures relating to the production of electricity from renewable energy sources. In particular, it allows small renewable plants (1 MW and 200 kW for wind plants) commissioned after 1 January 2008 to choose between green certificates and a feed-in tariff mechanism (called 'all inclusive tariff') for an incentive period of 15 years. Both green certificates and all-inclusive tariffs are differentiated by renewable energy source. Decree of 18 December 2008 brought implementation details. It introduces two main support mechanisms: Green Certificates and a fixed all-inclusive feed-in tariff (tariffa onnicomprensiva), with eligibility and remuneration levels depending on the renewable source and plant size. The decree defines the conditions, procedures and technical rules for accessing incentives, including plant qualification through the GSE, and sets thresholds for mechanisms such as net metering (scambio sul posto), thereby promoting the deployment of non-solar renewable energy generation in Italy.
