1 Stato dell arte delle tecnologie italiane: Offshore Wind Claudio Lugni (rappresentante Italiano TWG-OW) Roma, 29 Settembre 2017

2 Energy Union priorities Research and Innovation and Competitiveness SET Plan related actions Core priority 1: Number 1 in renewable energy: Action 1: Sustain technological leadership by developing highly performant renewable technologies and their integration in the EU's energy system; Action 2: Reduce the cost of key technologies.

3 Wind Energy in EU (I) Wind energy is the renewable energy technology expected to provide the largest contribution to the RE targets for 2020 and beyond. from: SET PLAN DoI Installed wind power capacity in the EU is currently around 140 GW: approx 127 GW of the capacity is onshore 13 GW is offshore. By 2020 total installed wind energy capacity could reach 210 GW (14% of elect. demand), and by 2030 it could reach 350 GW (21% and 24% of demand) The cost of onshore wind power is already competitive with other sources of electricity in a number of countries. Offshore wind represents a significant future opportunity: resources are stable and abundant and public acceptance is higher. Europe is the leader in offshore wind

4 Wind Energy in EU (II) To maintain European leadership 2 key issues need to be tackled: from: SET PLAN DoI 1 - Offshore wind costs must be reduced through, but not only, increased performance and reliability 2 - There is a need to develop (floating) substructures or integrated floating wind energy systems for deeper waters and wind energy systems for use in other marine climatic conditions, to increase the deployment possibilities and to improve the European position in the global market. from BFOWT (North Sea) to FOWT (Med & Baltic sea)

5 IL PIANO STRATEGICO ITALIANO da: SEN 2017 il significativo potenziale residuo tecnicamente ed economicamente sfruttabile e la riduzione dei costi di fotovoltaico ed eolico, prospettano un importante sviluppo di queste tecnologie.

14 Si ringrazia Ing. Luigi Severini The offshore wind farm in the harbour of Taranto has achieved two important goals, is the first (and only) example of offshore wind farm completely approved from Italian government, and will be the first wind farm in the Mediterranean sea. These are important results for us, and a positive flywheel for the development of industrial and technological Italian system. The project received the decree of environmental compatibility (Ministry of Environment and Ministry of Cultural Heritage and Activities - 24/07/2012), and the construction authorization (Ministry for Infrastructure and Transport - 27/06/2013). The wind farm, located in the external harbor of Taranto has a rated power of 30MW. The layout of the installation had a "MiBACT positive evaluation, this was a important milestone of the authorization procedure, not all projects reach this achivement, and I quote "the localization of the wind towers is ideal to industrial context of the harbor of Taranto, and improves the skyline without being invasive". 14
