The 50MWe AndaSol plant is located in the community of Aldeire in the Marquesado valley in the Province of Granada, Southern Spain. Thanks to the high altitude (1,100 m) and the desert climate, the Marquesado Valley offers exceptionally high annual direct insolation of 2,200 kWh/m²yr. The 549’360m² parabolic trough solar field is built-up by 1,008 EUROTrough collectors, arranged in 168 parallel loops. It will occupy app. 200 hectares of land. It will generate live steam of 100 bar/371°C to the reheat steam turbine with a cycle efficiency of 38%, gross. With an annual direct normal radiation of 2,200 kWh/m² per year, the AndaSol plant will generate almost 182 million kWh per year of clean solar electricity in 100% solar operation. The plant will be built, owned and operated by the specific project company, Partner 1. Partner 1 will sell as renewable independent power producer the generated solar electricity to the utility under the standard renewable power purchase terms regulated by the Spanish Royal Decree 2818/98. Using solar beam radiation as it’s primary energy, the solar plant will avoid approximately 172,000 tons of CO2 annually in Southern Spain otherwise being emitted by coal and heavy fuel oil operated power plants in the region.

 The project is supported by the European Commission, DG TREN because of these reasons:

  1. It is a first-of-its-kind, utility-scale demonstration of the solar thermal technology developments EUROTrough and Thermal Storage.

  2. Subsequent to the development of an advanced collector structure within the EUROTrough project, this demonstration plant will be the first opportunity to proof and demonstrate the technical and economic viability of the new collector design.

  3. Before the newly developed EUROTrough technologies can be utilized on a pure commercial base it is necessary to overcome the technical and economic risks of a large-scale installation.

  4. The AndaSol project will be the first application of molten salt-based thermal storage technology with parabolic trough collectors. The heat exchange between the HTF fluid circulating in the solar field, the molten salt storage medium and the water/steam cycle will be optimized in this commercial scale design.

  5. The procurement, installation and long time operation of new components within a working power plant scheme will enable the involved companies and research institutes to further improve components and production technologies. This will subsequently lower cost for following projects.
