2 A quick look at Pioneers in development and sustainability Present in 30 countries and across 5 continents. Turnover is in excess of 7.9 billion Euros. Net profit increased by 48% In 2007 Acciona is one of the premier international corporations working in the development and management of infrastructure services and renewable energy sources, employing more than 38,000 people worldwide. Acciona is listed on the IBEX-35 in Spain with a market capitalization of more than $16 billion.

3 A Company with a mission ACCIONA aims to reduce the world's CO2 emissions by 220 million tons by year This is a full one percent of the 18.4 billion tons needed from the world's power production industry by the 2030 deadline set by the Intergovernmental Panel on Climate Change. Weekly We avoid CO2 emissions We record the CO2 emissions avoided weekly and annually through our renewable energy production. Weekly: Tons Yearly accumulated: Tons Avoided CO2 emissions in 2007: Tons Nevada Solar One is an important part of ACCIONA's plan to meet that goal.

5 INTRODUCING... Nevada Solar One

6 NEVADA SOLAR ONE Long term Power Purchase Agreement signed with Nevada Power and Sierra Pacific March 2003 Amendment for expansion to 64 MW - approved in June 5, 2005 Groundbreaking Feb 2006 Turbine delivered on site Nov 2006 Utility Interconnection completed Nov 2006 Commercial Operation June

7 NEVADA SOLAR ONE - FINANCING The deal is the first leveraged lease structured financing for a U.S. Solar Power Project Equity Participants : JP Morgan is one of three equity investors in the $266 million project. The other two are an affiliate of Northern Trust and Wells Fargo. Debt participants are Banco Santander and Banco Bilbao Vizcaya Argentaria of Spain and Portugal's CAIXA Geral de Depositos.

8 NSO PROJECT LOCATION NSO Substation s Nevada Solar One is located in the El Dorado Valley approx 35 miles SE of Las Vegas, Nevada

9 Nevada Solar One - Infrastructure Location: Boulder City, NV Excellent Solar resource Moderate wind speed Near major grid substations Water available

10 Nevada Renewable Portofolio Standard Investment Tax Credit Nevada s current RPS adopted in 2005 requires the state s electric utilities to generate or acquire a minimum of 6 percent of electricity sold to retail customers from renewable energy systems in 2005 and 2006, and gradually increases the standard until it reaches 20 percent in The ITC (investment Tax Credit) play a critical role in the development of CSP in the US 30,000 MW will potentially be installed by 2025 with the ITC vs MW with reduced ITC and 500 MW with No ITC

15 SIMPLE SCHEMATIC OF PARABOLIC TROUGH OPERATION (North-South Axis) Concentration Ratio 71:1 (71 Suns) NSO utilize Parabolic Trough Collectors which is a Concentrating Solar Power (CSP) Technology CSP Technologies utilize Direct Normal Radiation (DNR) which is measured in terms of Watts per Square Meter

16 Parabolic Trough Collector

17 NSO - Simple schematic The solar thermal industry and especially the Concentrating Solar Power industry are being developed worldwide in a rapid pace, this should attract more large manufacturers to consider the production of solar field components at attractive costs.

30 Auguste Mouchout French inventor of the first known device that directly converted solar energy into mechanical power (1865) in 1860 after expressing grave concerns about his country's dependence on coal. "It would be prudent and wise not to fall asleep regarding this quasi-security," he also wrote. "Eventually industry will no longer find in Europe the resources to satisfy its prodigious expansion. Coal will undoubtedly be used up. What will industry do then?" Frank Shuman ( ) was an American engineer and solar energy pioneer noted for his work on solar engines, especially those that used solar energy to heat water that would produce steam. Shuman's visionary ideals, most of which were not publicly accepted until sixty years later, were evident when he made the statement, "One thing I feel sure of... is that the human race must finally utilize direct sun power or revert to barbarism." Frank Shuman declared more than 90 years ago, Solar Energy is "the most rational source of power."
