Siemens Energy has received an order for a solar field in Extremadura, Spain, from the Spanish EPC UTE Termosolar Olivenza (Acciona Infraestructuras, Acciona Ingeniería and Seridom) who acted as turnkey contractor for the CSP Plant Termosolar Olivenza 1, owned by Ibereólica Solar Olivenza, S.L. The scope of supply encompasses the turnkey solar field, including the solar receivers. The parabolic trough power plant with a capacity of 50 megawatts (MW) will be built in Olivenza (Badajoz) and includes 123 loops of parabolic trough collectors. The CSP plant Termosolar Olivenza 1 is planned to go operational by the end of 2012. The capacity of the plant is sufficient to provide ecofriendly power for about 50,000 Spanish households.
"Siemens is able to design, construct and integrate flexible solar fields to address the project-specific needs of our customers," said Avi Brenmiller, CEO of the Siemens Business Unit Solar Thermal Energy. With this type of solar thermal power plant the sun's energy is concentrated by parabolic mirrors on a small surface area. A receiver tube is located in the focal line of the half-open sun-tracking mirrors. Thermo oil as the heat transfer medium circulates within the tube. The heated oil produces steam in a heat exchanger, which is used to generate electricity with the aid of a steam turbine-generator.
Solar power plants are part of Siemens' Environmental Portfolio. In fiscal 2010, revenue from the Portfolio totaled about EUR28 billion, making Siemens the world's largest supplier of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by 270 million tons, an amount equal to the total annual CO2 emissions of the megacities Hong Kong, London, New York, Tokyo, Delhi and Singapore.
