The Solar Thermal Central of Tavira

The study of Environmental Impacts included: (1) the study of characterization of the reference situation of the area of influence of the project; (2) the assessment of the impacts resulting from its implementation; and (3) the definition of the measures to minimize the negative impacts, to the stages of construction, operation and decomissioning/conversion of the operation.

The Central thermal solar de Tavira involves the installation of 69 336 m² of mirrors of the CLFR - Compact Linear Fresnel Reflector type, and works an average of 2442h / year to the nominal power, with an average annual production of 12.7 GW helectricity. It also foresees the use of a steam turbine for saturated steam attemperatures around 250 ° C, a relatively low value from the point of view of solar collectors, which allows the CLFR technology.

The general characteristics of central are:

• Power peak ........................................... 7.0 MWe
• Nominal power: ...................................    5.2 MWe
• Area collectors (mirrors) ...................... 69 336 m²
• Land area used ...................................100 000 m²

Overall dimensions of the collectors system structures:

• 8 rows of mirrors / reflectors, eachpiping / absorber;
• Each line has 10 rows of mirrors /reflectors;
• Long lines have a length of 386 m;
• The width of each row of mirrors is 29 m;
• The pipes - absorber are at a height of 15 m;
• Mirrors and circular structure of support of the same have a height of about 2.5 m.
