DOS PLANTAS TERMOSOLARES GEMELAS ENTRAN EN LÍNEA EN ESPAÑA; CADA UNA SIGE FUNCIONANDO 7,5 HORAS DESPUÉS DE LA PUESTA DEL SOL NIGHTFALL (de un artículo en Team TreeHugger [nick@treehugger.ccsend.com]; Ene.20,2012)

Un análisis que condujo SEDER con Masdar muestra que para el 2020 la energía solar concentrada será “más o menos comptetitiva en el rango de precios de la electricidad en España”. De hecho, en este momento los costos de energía solar concentrada están un 15% detrás de los proyectos de electricidad fotovoltaica, con el obvio beneficio de poder generar energía después del anochecer – y esta es la razón por la que una compañía minera de Chile que opera las 24 horas está considerando desarrollar un proyecto con Torresol.

TWIN 50 MW SOLAR THERMAL PLANTS GO ONLINE IN SPAIN; EACH CAN RUN 7.5 HOURS AFTER NIGHTFALL (from an article in Team TreeHugger [nick@treehugger.ccsend.com]; Jan.20,2012)
Two identical 50 megawatt solar thermal plants are now up and running in Spain, each sending enough clean power to the grid to power over 40,000 homes. Torresol Energy, the joint venture between Abu Dhabi's Masdar and Spain's SEDER, announced that its second and third concentrated solar power plants are operating smoothly—the first was the renowned Gemasolar solar tower—and that plans for more are in the works.
Valle I & II, the new plants, each utilize parabolic trough technology—where rows of curved mirrors concentrate sunlight in order to heat a liquid, which is turned into steam to power a generator. The plants will be able to store enough energy to continue operating seven and a half hours after sundown.
An analysis SEDER conducted with Masdar shows that by 2020, concentrated solar will be "more or less competitive in that range with electrical prices in Spain."
Indeed, as of now, concentrated solar's costs only lag around 15% behind standard photovoltaic solar projects, and there's already the obvious benefit of being able to generate power after nightfall—which is why a mining company in Chile, which operates around the clock, is seeking to develop a project with Torresol.
Solar thermal has long been touted as one of the most promising renewable technologies; with every plant that comes online, the case grows stronger yet.
