Energy efficiency decrees (1/6)
• Issued in April 2001
• Innovative strategy that combines a command and control approach with a market based instrument
Casaccia 09.01.2007 5
Energy efficiency decrees (3/6)
• On July 2004 was issued an amended version of the two decrees with the following main changes:– Modifications in the distribution of annual quantitative
targets;– Postponement of the implementation period (from
2005 to 2009)– Introduction of flexible mechanism in the deadline for
achieving the annual savings
Casaccia 09.01.2007 6
Energy efficiency decrees (2/6)
• Distribution System Operators* (DSO) are required to achieve quantitative targets of energy efficiency improvements in end-uses
• The way for achieving these objectives is left to the market forces (energy efficiency titles or white certificates)
* < 100.000 customers at Dec. 2001

Energy efficiency decrees (5/6)
• The annual target (*) for each DSO at (t) year is proportional at the share of energy distributed in the year (t-2) by each distributors
(*) at least 50% of savings must be achieved in the field where DSO works
Casaccia 09.01.2007 10
Energy efficiency decrees (6/6)
• Energy saving targets can be achieved through projects implemented by:
– DSO, directly or via controlled companies
– Energy Service Companies (ESCOs)
Casaccia 09.01.2007 11

Energy Efficiency Titles (TEE)or
White Certificates (WhC)
• 1 WhC for 1 toe of saved primary energy
Casaccia 09.01.2007 15
White Certificates (WhC)
• WhC are issued by Electricity Market Operator (GME) once it has been certified that a defined amount of energy saving will be attained by project implementation
Casaccia 09.01.2007 16
Typology of WhC
• Type 1: certificates savings of electricity
• Type 2: certificates savings of gas
• Type 3: certificates savings of other fuels
Casaccia 09.01.2007 17
Sanctions
• proportional and in any case greater than the investment needed to compensate the non-compliance

Measurements and Verification of energy savings (M&V)
• The definition of technical rules, the implementation, monitoring and enforcement of the whole mechanism are under the responsibility of the Authority for Electric Energy and Gas (AEEG)
Casaccia 09.01.2007 20
Measurements and Verification of energy savings (M&V)
• The AEEG developed three evaluation methods:– Default method (no measurement; installed units are
considered according to their average energy saving)– Engineering method (some measurement of technical
features)– Energy monitoring plan (direct measurement of
consumption before and after the project)

Measurements and Verification of energy savings (M&V)
• On January 2006, in implementation of the Ministerial Decrees, the Authority has decided to draw on the services of ENEA (Italian National Agency for New Technologies, Energy and the Environment).
Casaccia 09.01.2007 24
Measurements and Verification of energy savings (M&V)
The main activities carried out by Enea will be:
1) technical verification and evaluation of the projects;
2) monitoring to ensure that the energy saving projects under evaluation are being implemented correctly;
3) the adoption and up-dating of detailed, standardised technical worksheets for use in evaluating projects and quantifying results.
Casaccia 09.01.2007 25
Main results 2005
• Many ESCOs authorised (700 till now)
• 1000 projects implemented;
• 0.28 Mtoe of energy saving achieved (with respect to a target of 0.15 Mtoe);
• 0,75 Mton of CO2 reduced (equivalent to a CO2 emitted from a central power of 160 MW)
