Un referente en energía solar.

Entre los términos municipales de Fuente Palmera, Guadalcázar, Almodóvar del Río y Posadas, en la provincia de Córdoba, se enuentra Africana Energía, una central solar termoeléctrica de 50 MW y la mayor de España con 270 hectáreas, 550.000 m2 de espejos y 168 lazos. El alto grado de innovación de las instalaciones y su funcionamiento la sitúan como un referente no sólo en Andalucía, sino también en el país. 

AFRICANA ENERGY

A SOLAR ENERGY BENCHMARK

Africana Energía is located between the municipalities of Fuente Palmera, Guadalcázar, Almodóvar del Río and Posadas, in the province of Córdoba. This is a 50 MW thermoelectric solar plant, the largest in Spain, measuring 270 hectares, and with 550,000 m2 of mirrors and 168 loops.

The high degree of innovation of the facilities and the operation of these, position the plant as a point of reference, not only in Andalusia but also in Spain. Africana Energía employs cylinder-parabolic technology to capture solar rays, a clean and mature technology ready for major deployment, and a system of heat storage that enable it to provide energy even at night-time or during cloudy weather.

CYLINDER-PARABOLIC TECHNOLOGY

The process of producing electricity using the sun as the main source of energy involves using a field of cylinder-parabolic collectors to capture solar radiation. These collectors then concentrate solar radiation on heat absorbing tubes.

These tubes carry a synthetic oil that reaches temperatures of up to 400°C and which travels to a series of heat exchangers to produce overheated steam.

The energy in this steam is turned into electricity using a conventional steam turbine and a generator connected to this.

ENERGY STORAGE

Africana Energía is a commitment to efficiency and on-going technological innovation, a hallmark of identity that is present in both the engineering as well as the performance of the power plant.

The plant has a system of heat storage with molten salts that provide energy even during conditions of reduced radiation and for more than seven hours. These salts, stored in two tanks, exchange heat with the fluid from the solar field, thus continuing with the steam generation cycle that moves the turbine in order to finally produce electricity.

By the same token, the system has a range of ancillary heat systems that ensure temperature control and perfect synchronisation with the distribution grid.

KEY FIGURES OF AFRICANA ENERGÍA

The construction of Africana Energía has been carried out in optimum time.

The groundwork began in summer 2010. This involved moving more than 2,000,000 m3 of soil, a stage that was carried out prior to the actual construction task, which began in 2011, and which has required the discharge of more than 50,000 m3 of concrete.

Turning Africana Energía into a high technological level reality has required installation of 8,064 solar collectors, each comprising 28 mirrors; 225,792 in total. In turn, 24,192 receptor tubes and 5,000 valves have been installed in these collectors. Moreover, around 30,500 tonnes of salt have been smelted to fill up the heat storage tanks.

Other major works at the plant have involved telecommunications and energy transportation: Africana Energía has required the deployment of over 300,000 metres of cable.

The plant’s water autonomy has also been made possible thanks to the construction of two large reservoirs capable of storing 500,000 m3 of rainwater, thus reducing the equivalent consumption from other natural sources.

The Africana Energía thermoelectric solar plant is far more than just energy; it is research, engineering, sustainability, development, technology, infrastructures...

It is creativity and innovation in a commitment to the future.
