Centrale solaire de Llo

"At the height of Llo, the Solar Thermodynamic Power Plant dominates Cerdanya. As an extension of its 153,000m² of solar mirror area, in an area of ​​36 hectares. The plant has 95,200 solar mirrors in 23,800 support boxes and poles, divided into 2 parts, the west field being twice the area of ​​the east field. The plant has a capacity of 9 megawatts with thermal energy storage, which represents the electricity consumption of more than 6,000 homes. It has 9 tanks of 90 tons of 120,000 m³ each, totaling more than 120 m³ each, totaling more than 1,000 m³, where part of the steam produced by the Oeste field is stored. And they can store up to 80 bar of pressure, which corresponds to 4 hours of operation of the installation. The steam from the East field goes straight to the turbine. The site is organized in 170 modules with 10 rows of 14 mirrors each. Each module is managed by a system of coding connectors, trackers, which position the mirrors in relation to the sun. The plant is designed to operate 100% in winter, including storage. On the other hand, in the summer, the apex of steam is produced. At night, when there is no more sun, the tanks release the stored steam and the plant can continue to operate. Energy production is 20 GWh per year. 23,800 "caissons" were required to build and 1,800 round-trip transportation of materials between the workshops and the site of the plant during 24 months of construction. some numbers. Cost: 60 M €. 153,000 m2 of mirrors installed. 12 km of tubes containing water (heated to 286 °) and transformed into steam (70 bar). 23,800 boxes with 95,200 mirrors. 9 tanks of 120 m3 (that is, almost 1000 m3) guarantee the storage of saturated steam at 80 bar. Central power: 9 MW electric. Electricity production from the plant: 20,200 MWh / year. Storage capacity: 4 hours. 100% recyclable."

"Mooie installatie. Zou deze manier van duurzaam energie opwekken ook in toekomstige projecten nog toekomst hebben nu zonnepanelen en batterijen zoveel goedkoper worden?"

"La Central Solar de Llo produeix energia elèctrica per 6000 llars diuen, segurament és necessària, pero l'impacte visual que produeix es innegable."
