| Cobra begins construction of Extresol-1 Grupo Cobra, part of the ACS Group's Industrial Services Division, began the construction of the thermo-solar power plant Extresol-1 in the province of Badajoz. The first stone of what will be Europe's second largest solar power plant was set in place by the President of Extremadura, Guillermo Fernández Vara in the town of Torre de Miguel Sesmero (Badajoz). Construction will be completed in 2009. Grupo Cobra is the sponsor of the project and will invest a total of €300 million. The plant will have 624 collectors occupying 510,120 m² of a 225 hectare plot. The electricity generated wil supply an equivalent of 30,000 homes and avoid 149,000 tonnes in CO2 emission per year. The Extresol-1 project uses cylinder-parabolic solar energy collectors, whose use a solar energy concentration system that has a sunlight monitoring mechanism that follows the sun to assure that the collector continuously receives direct sunlight. By following the sun from the east to the west the collectors reflect and concentrate the direct sunlight on absorbent tubes located along the focal line of the reflective surface. These absorbent tubes circulate the heat transfer fluid, normally synthetic oil, that is heated by the concentrated sunlight up to temperatures of 400º C. write your comments about the article :: © 2007 Construction News :: home page |
