  1. Wind Development Strategies:environmental acceptance and critical aspectsLuigi La Pegna Head of Projects – Renewable Energies Business Unitluigi.lapegna@enel.it • EWEC 2007 – Milan, 2007 May 9th

  2. Summary • Overview on Enel’s Renewables • Wind Investment Strategies and Targets • Wind Environmental acceptance and critical aspects

  3. A brief overview of Enel • Enel is the third* largest listed utility in Europe with a market capitalisation of EUR 50 billion. • The Italian Economy Ministry owns 31.6 %** of the company, leaving a free-float of some 70%, with 2.3 million shareholders. • Its 58.548 employees work in 16 countries, producing and distributing power and gas in Europe, North & Latin America. • Thanks to the strong commitment to Corporate Social Respon-sibility, Enel has been included in the world’s most selective ethical indexes, such as the Dow Jones Sustainability Index. Enel aims to be the most efficient, market driven, quality focused provider of power and gas, creating value for customers, shareholders and people * as of 28th March 2007 ** 21,4% directly and 10,2% indirectly through state-run lender Cassa Depositi e Prestiti

  8. Enel’s Production Mix <1% Domestic Generation & Energy Management Environmental impact Assessment

  9. Environment and innovation Growth in renewables – Italy and International • 1,500 MW in wind • 100 MW in hydro • 100 MW in geo Growth in renewables € 3.3 bn • Innovative solution for renewable energy • Energy efficiency and distributed generation • Toward “zero emissions” and the hydrogen frontier Innovation projects € 0.8 bn An ambitious plan built on material projects

  10. Growth in renewables 2003-2006 2007-2011 ITALY - Domestic Generation & Energy Management • 13 plants started up in 2006 • 44 MW additional renewable capacity achieved in 2006 • 400 MW of additional domestic capacity in 2007-2011 Investments (€bn) Delivering Enel’s strategy in renewables

  11. ITALY - Domestic Generation & Energy Management Off Shore Wind Farms • Present situation: rapid development of technology in Northern Seas and no installation in Mediterranean Sea • Off-shore wind farm in Italy defined as part of Enel Business Plan • Design and execution plan started in 2005 and undergoing. • Site definition within 2007, environmental studies and authorization within 2009. • Realization of 1 or 2 off-shore wind farms in Italy (50 to 200MW) within 2011

  12. Critical to wind developmentPublic opinion opposition 12 december 2006, four different Italian regions

  13. 11 stamps !! Authorization 16 months from presentation (dec 04 – may 06) Critical to wind development Bureaucracy Replacement of 8 old WTGs (not working) with new WTGs. Same number, same dimensions, same power

  14. Wind installation in Europe New installations 2006 Germany 2,233 MW + 12% Spain 1,587 MW + 16 % Denmark 22 MW - Italy 421 MW + 24%

  15. Mainly prejudices, few real criticalities Critical to wind development Main items As commonly reported • Visual impact • Noise • Impacts on birds and wildlife • Electromagnetic pollution

  16. Visual impact: the past

  17. Visual impact Enel project advise in lay-out definition • Avoid “forest” effect • Underground paths for power cables • Accurate definition of plant internal roads and finitures through condivision with local population • Specific attention to maintenance of wind farms through operational period Tula wind farm (Sardinia) “Sa Turrina Manna”

  18. Visual impact Colours • Advanced WTGs design and study of colours effect in different seasons • WTGs transformer internal at supporting tower Spring Wind Farm Sclafani Bagni (Sicily) “Incatena Cugno” Fall

  19. Visual impact Transportation and erection • Accurate study to minimize impact and reduce service infrastructures at minimum essential • Fast and efficient restoring of ‘ante operam’ conditions after erection and in final plant dismountling phase.
