VALLE 1 and VALLE 2

VALLE 1 and VALLE 2 are two adjacent 50 MW plants of electrical energy generation with similar characteristics located in San José del Valle (Cadiz, Spain). The construction of these plants started in March 2009.

The technology used by these two twin plants is the parabolic trough collectors. Each of them will consist of a solar field of 510,000 m2 of SENERtrough kind collectors, previously developed and qualified by SENER. These collectors will count on a high accuracy optical sensor that will follow the sun from east to west to accumulate, this way, the maximum solar radiation.

The expected net power production for each of the VALLE 1 and VALLE 2 plants is 175 GWh/year. Thanks to their respective thermal storage systems, with 7 hours capacity, both plants will provide with energy without fluctuation or interruptions, contributing to the power supply stability for more than 3,500 hours per year.

By using the concentrated solar radiation as the primary energy, VALLE 1 and VALLE 2 projects will save around 95,000 CO2 emissions tons a year. Thus, they will remarkably contribute to comply with the goal of reaching 12% of the Spanish energy requirements from renewable sources in 2010.
