Biomass systems: new requirements for incentives
What the European RED II Directive is about
What the European RED II Directive is about
With Legislative Decree 199/2021, which was published in the Official Gazette on 30 November and came into force on 15 December, Italy has implemented the European Directive for the promotion of the use of energy from renewable sources, commonly known as RED II.
RED II defines the tools, mechanisms, incentives and institutional, financial and legal framework necessary to achieve the objectives of increasing the share of energy from renewable sources; dealing with the subject of renewables, the regulation also regulates some of the measures necessary for the implementation of the PNRR, the National Recovery and Resilience Plan for energy from renewable sources, in accordance with the PNIEC, the National Integrated Energy and Climate Plan.
The sustainability criteria on renewable energy are applied to electricity, heating and cooling (or fuel) installations using solid fuels from biomass and having a thermal input of 20 MW or more, or to those having a total rated thermal input of less than 2 MW and using gaseous fuels from biomass.
Pellet requirements
Pellet requirements
This legislative decree regulates the criteria applicable to all plants producing thermal energy from renewable sources that apply for incentives. These are minimum requirements that may be further raised in the decrees adopting the individual incentives. The criteria include both specific technological requirements for each type of generator, and requirements relating to the quality of the biofuels that can be used, including pellets.
In the specific case of pellet requirements, the Decree accepts the proposals previously made by AIEL, according to which only systems and appliances that use fuel that meets the following requirements can be incentivised:
- for thermo-stoves the pellets must necessarily be of quality class A1, while for boilers they must be of the same or better quality than that for which the generator has been certified (≤500 kW) or tested in situ (>500 kW);
- pellet certification must be issued by an accredited certification body in accordance with ISO/IEC 17065, based on analyses of the properties of the biofuel carried out by an accredited body in accordance with the UNI EN ISO 17225-2 series of standards;
- the pellet purchase documentation must show the quality class and the identification code issued by the accredited certification body to the producer and made available by the latter to the distributor.
What will no longer be valid
What will no longer be valid
It will therefore no longer be possible to access the incentives by using biofuels with self-declarations regarding the quality class of the pellets, nor laboratory analyses arranged independently by production and distribution companies, nor analyses carried out by laboratories that are not accredited or only partially accredited with respect to the analysis methods provided for by the ISO 17225-2 standard.
