AndaSol 1 & 2 solar power plants 50 MWe in Guadix (Granada), Spain.
The AndaSol 1 and AndaSol 2 power plants, located in Guadix (Granada), are the first solar power plants to incorporate a thermal storage system using molten salts. Through this system of molten salt storage, the plant’s power capacity and the energy demand can be assured. This system can operate 24 hours a day and improves the production costs, as well as the costs related to the maintenance and operational staff's productivity.
In order to study the project's feasibility, SENER's SENSOL software was used, which integrates the project's technical and economic studies into a single program. This is a piece of software developed by SENER specifically for these types of solar applications, and its effectiveness has already been demonstrated in more than 25 solar power plants throughout the world.
For this project, SENER has carried out the basic engineering, the detailed engineering and has participated in the Lump Sum Turn Key (EPC) contract.
