4 GSE s activities Management of support schemes and energy services for RES, CHP and Energy Efficiency (electricity, heating, transport): management of dematerialized applications, plants qualification and inspection, contracting, management of measures and incentives(services, etc. Energy management: participation in the electricity market (energy withdrawn in the context of incentives/services managed), forecasting of electricity production, management of unbalancing costs, calculation of curtailed wind power generation, etc. GSE aims to reduce renewables unbalancing costs so it is crucial accurate forecasting of non-programmable plants. CO2 auctions : we are in charge of auctioning Italian emission allowances on the European Common Auction Platform (CAP) Studies, statistics, monitoring on RES and EE: statistics, monitoring reports for the EU, analysis of economic and employment impacts, environmental effects, authorization procedures, generation costs in Italy and at international level, analysis and comparison of international policies Support to institutional policy makers and public administration International activities: participation in the main international associations (IEA, IRENA, RES4MED, etc.) and in the energy projects and studies funded (Concerted Action on RED, PV Parity, etc.) Information and training: promotion of RES and EE (workshops, reports and guides, training, etc.) Support to Italian RES operators ( Corrente project) to contribute to improving the chain visibility and to introducing the operators into the international markets - 4 -

7 RES Italian instruments : HEAT (and efficiency) support mechanisms Grant Quota-obligation scheme Fiscal Incentives Heating Account Incentives are intended to support part of investment costs through yearly installments and are granted for a period varying between 1 and 5 years, depending on the type of intervention realized (heat pumps, biomass boilers and stoves, solar thermal, small energy efficiency projects) [Financed by the gas tariffs ] White certificates White certificates are tradable instruments giving proof of the achievement of end-use energy savings through energy efficiency improvement initiatives and projects. It is based on the obligation for electricity and natural-gas distributors to achieve yearly quantitative primary-energy saving targets [ Financed by distributors, gas and electric tariffs ]. Tax detraction Government provides a tax detraction of 65% of the expenses for interventions of energy re-qualification on existing buildings, including the replacement of old heating systems with new RES heating devices [ Financed by taxation ] Yearly cumulative spending limit: 900 mln - 7 -

8 RES Italian instruments : TRANSPORT support mechanism Quota-obligation scheme Biofuel certificates In Italy gasoline and diesel distribution companies have the obligation to sell a quantity of biofuels equal to a certain quota of the total fossil fuel energy content sold in the same year (quota obligation). The 2014 quota is equal to 4,5%. The companies can fulfill their obligation by blending biofuels with fossil fuels or, also, by acquiring the equivalent quota of certificates. Certificates are issued by GSE on the basis of companies annual declarations. Every certificate corresponds to a 10 Gcal of biofuel, with the exception of biofuels produced from waste, by-products or non-edible feedstock, which receive 2 certificates every 10 Gcal (double counting mechanism). All the biofuels consumed in Italy must comply with the European sustainability criteria, in order to receive the certificates

21 RES-E in the market : the GSE s forecasting activity Forecast & Optimization of variable renewable generation Main target The commitment of GSE aims to reduce energy imbalances, and related costs. To this end, it is crucial to perform accurate forecasting of the energy produced from the non-programmable renewable sources.

23 RES monitoring : relation between costs and incentives (example PV) Evolution of generation costs of PV plants in Italy ( /MWh) in comparison with total income ( /MWh) arising from energy production Generation costs and total income refer to ground-mounted PV plants with P > 1 MW, while developed capacity includes all plants. The fast decrease of generation costs in was not combined with the same rate of reduction of energy remuneration, thus determining the economic conditions for an explosive development in Source: GSE studies

27 RES international monitoring : analyses of POLICIES and results The legislation relies on the GSE processing of an annual report of analysis and comparison of support mechanisms for RES in Europe. At the extra-european level, the monitoring is carried through country reports that: provide a detailed overview on existing support systems for RES and its energy context in which they operate; constitute a first approach for potential investors who would "enter" into the country; provides a short summary of the macro-economic and commercial context

28 RES policies : some tips for efficient policies The extensive monitoring activity of Italian and international trends allows deriving the following recommendations for efficient RES development: Guarantee transparency and try to guarantee continuity of RES policies, in a long-term perspective, in order to: - Minimize country/investment risk, encouraging foreign investors - Promote a progressive development, consistent with the national context Provide an integrated approach: o o o o o o o o o o Look at RES not as an aim in itself, but as a piece of a national energy and economic policy Set long-term RES targets Identify the most appropriate instruments for the national context Define a continuous, progressive decrease of possible incentives Promote national and local economic development Plan the development of the electricity grid in accordance with the RES targets Promote efficient integration and empowerment of variable RES into the grid and the market Define efficient authorization procedures Take care of training and information And (last but not least)

29 RES policies : the virtuous circle of a broad spectrum monitoring o monitor! A comprehensive monitoring activity (costs, markets, tariffs, infrastructures, technologies, net economic effects, investments, value added, jobs, balance of trade, environmental and social impacts, etc.) can provide effective feedback on strategic priorities, targets and instruments Instruments (not only financial ones) Targets «Internal» monitoring: effectiveness, efficiency Considering interaction with other policies «external» monitoring: National and international trends (technology, economic, and political trends) Strategic Priorities Feed-back
