RES Support Schemes in Italy - 1
Quantity-based instruments
• Quota obligation to source a specific percentage of electricity from RES generation; Tradable Green Certificates (TGC) prove compliance with the obligation
Price-based instruments
• Feed-in tariffs: RES generators are paid a fixed price, irrespective of the wholesale price of electricity
• Feed-in premium: RES generators are paid a premium price in addition to the wholesale electricity price
• Investments subsidies granted mainly by local governments

RES Support Schemes in Italy - 2
Incentive typology Plants involvedDuration of the incentivation
Incentivated volumes of energy
Green certificatesRES and "hybrid" plants entered into service since 1 april 1999
12 years for plants entered into service between 1 April 1999 and 31 December 2007; 15 years for plants entered into service since 1 January 2008
Net electricity produced by plants entered into service between 1 April 1999 and 31 December 2007; net electricity produced multiplied by a
coefficient for plants entered into service since 1 January 2008. Concerning "hybrid" plants,
incentivated energy is that attributable to RES.
Feed-in premium for photovoltaic plants
Photovoltaic plants entered into service after 30 September 2005
20 years Produced energy
Feed-in premium for thermodynamic solar
plants
Thermodynamic solar plants entered into service after 18 July
200825 years
Net electricity produced. Concerning "hybrid" plants, incentivated energy is that attributable to
solar source.
Feed-in tariff("all inclusive" tariff)
Plants entered into service since 1 January 2008; wind plants with
power capacity less than 200 kW; other RES plants, except solar plants, with power less than 1
MW
15 yearsElectricity injected in the grid. Concerning "hybrid" plants, incentivated production is that attributable
to RES.
Feed-in tariff(CIP 6 mechanism)
Plants alimented by renewable and "renewable assimilated" sources; the mechanism was replaced in 1999 by the green
certificates market
8 years for the incentive component, correlated to major costs relative to different plant typologies; mainly 15 years for
the component relative to avoided costs
Produced and injected energy

GSE – Energy Services Operator
State-controlled company (fully owned by Ministry of Finance)
It owns GME (Electricity Market Operator) and AU (Single Buyer)
It is responsible for promoting and developing renewables resources:
• Buys electricity generated by renewable and assimilated sources and sells it in the market
• Issues Green Certificates and monitors producers’ and importers’ compliance with renewables obligation
• Certifies plants using renewables sources
• Issues the Guarantee of Origin (GO) of electricity generated by renewables
• Manages the scheme that stimulates electricity generation by photovoltaic plants and solar thermodynamic plants
• Certifies co-generation plants

Renewables Costs and Electricity Prices - 2
Rough estimate of impact on electricity prices
• Around 8 euro/MWh in 2009 (on accrual basis)
Estimated impact of TGC on wholesale prices
• Around 2 euro/MWh corresponding to 3% of wholesale electricity price in 2009
Estimated impact of carbon costs (EU ETS) on wholesale prices
• Around 1 euro/MWh corresponding to 1.4% of wholesale electricity price in 2009

EU Climate and Energy Policy
March 2007, EU Council
Climate and energy targets to be met by 2020:
• A reduction in EU greenhouse gas emissions of at least 20% below 1990 levels
• 20% of EU energy consumption to come from renewable resources (of which 10% in the transport sector)
• A 20% reduction in primary energy use compared with projected levels, to be achieved by improving energy efficiency
14
EU Climate and Energy Package - 1
December 2008, EU Council and Parliament
Binding legislation:1. A revision and strengthening of the Emissions Trading
System (EU ETS). A single EU-wide cap on emission allowances will reduce the number of allowances available to businesses to 21% below the 2005 level in 2020.
2. An 'Effort Sharing Decision’ governing emissions from sectors not covered by the EU ETS, such as transport, housing, agriculture and waste. Specific national targets will cut the EU’s overall emissions from the non-ETS sectors by 10% by 2020 compared with 2005 levels.
3. Binding national targets for renewable energy which collectively will lift the average renewable share across the EU to 20% by 2020.
4. A legal framework to promote the development and safe use of carbon capture and storage (CCS).
The package does not address energy efficiency improvements. This is being done through the EU’s
Energy Efficiency Action.
15
EU Climate and Energy Package - 2
Italy’s targets:
• 17% of energy consumption in 2020 to come from renewable resources
• A reduction in EU greenhouse gas emissions of 13% by 2020 compared to 2005 in sectors not covered by the EU ETS
• No specific target for sectors covered by the EU ETS since the cap applied from 2013 is EU-wide
16
Compliance costs for Italy - 1
Based on EU Commission Impact Assessment (published in 2008)
Assumptions:
• Allowed use of CDM/JI credits (from Kyoto flexible mechanisms) to reach the emissions reduction target
• No RES trading within EU and with Third Countries to reach the renewables target
Estimated results for reaching simultaneously both RES and GHG emissions reduction target:
• Yearly compliance costs around 10 billion euro (2005 prices) from 2011 thru 2020
• Compliance costs around 0.9% of GDP in 2020
17
Compliance costs for Italy - 2
AEEG estimates for RES only compliance costs
Assumptions:
• Italy’s potential for RES deployment: 21 Mtoe of which 9 Mtoe (104 TWh) for electricity generation (Italian Gvmt Position Paper)
• No RES trading within EU and with Third Countries to reach the renewables target
• Linear deployment of RES from current situation and extension of existing support measures thru 2020 while gradually halving support levels
• Energy efficiency measures to reduce final consumption by 17% with respect to EU baseline projection in order to meet the RES target of 17% with a deployment of RES power plants equal to the potential
18
Compliance costs for Italy - 3
AEEG estimates for RES compliance costs
Results:
• Compliance costs accounting to more than 5 billion euro in year 2015 and around 7 billion euro in year 2020
• More than 3.5 billion euro in year 2020 for supporting PV plants deployment

Tradable Green Certificates reference prices
• In the period 2002-2007 the reference price of TGCs, issued by GSE on his behalf and sold into the power exchange with reference to RES-sourced CIP6 plants, was based on the difference between the cost of purchasing electricity from supported CIP6 plants and revenues from the sale of such electricity
• Since 2008 the reference price of TGCs is computed as the difference between a predetermined price (180 €/MWh) and the sale price of electricity produced by RES and micro plants in the previous year
