  • Where it all began… A smarter way of thinking “Europe 2020 is the EU's growth strategy for the coming decade. In a changing world, we want the EU to become a smart, sustainable and inclusive economy” José Manuel Barroso President of the European Commission February 1, 2014 Stefano Zanin - Marketing
  • EU Climate-Energy objectives for 2020 The 20-20-20 targets represent an integrated approach to climate and energy policy that aims to combat climate change, increase the EU’s energy security and strengthen its competitiveness: • 20% reduction in EU greenhouse gas emissions • 20% of EU energy consumption from renewable resources • 20% improvement in the EU energy efficiency To achieve the 20-20-20 goal it is necessary to ensure sustainability, safety and competitiveness. Existing power networks must evolve and become “smart”. February 1, 2014 Stefano Zanin - Marketing
  • Evolution towards “greener” sources EU first started to move towards the growth in production from renewable sources, encouraging every Member State to adopt specific legislation to promote energy production from wind power, solar plant, hydroelectric and biomass. In Italy the growth has concerned mainly wind power and solar plant  total amount of installed energy is about 20% of total installed production capacity but could theoretically cover almost 40% national demand in electric power February 1, 2014 Stefano Zanin - Marketing
  • Overview of current Italian situation Subsidies and incentives (1) Wind, Biomass, Geothermal, and others: • Green Certificates  1 per MWh (2013 average market value ≈ 85€) • Energy produced to be sold with: market exchange, net metering, simplified purchase and resale • Comprehensive tariff (energy value + incentive)  ≈ 0,30 €cent/KWh • Duration of incentives formula  15 years • Upper limit for cumulated annual incentives  5,8 bln€/year Photovoltaic: • First years of subsidies for 3÷20KW PV plant  ≈ 0,50 €cent/KWh • Feed In tariff for 3÷20KW PV plant 1st half 2013  ≈ 0,16 + 0,08 €cent/KWh • Duration of incentives formula  20 years • Upper limit for cumulated annual incentives  6,7 bln€/year February 1, 2014 Stefano Zanin - Marketing
