The Hassi R'Mel power plant near Hassi R'Mel in the Algerian province of Laghouat is a hybrid power plant that combines a solar thermal power plant with a conventional gas and steam combined cycle power plant. It has a total output of 150 MW, of which 30 MW can be provided by solar energy , and is the world's first combined cycle solar hybrid power plant. The operator of the plant, which went into operation in May 2011, is the Spanish company Abengoa .

technology

The solar thermal part of the power plant consists of 224 parabolic trough collectors , which together have an aperture area of 183,860 m². The collectors are from Abengoa and the absorber pipes from Schott Solar . The thermal energy is transferred to a thermal oil , which is heated from 293 ° C to 393 ° C in the collector field. The collector field can provide an electrical output of 25 MW.

The conventional power plant section with an output of 130 MW is a combined cycle power plant consisting of two SGT-800 gas turbines and one SST-900 steam turbine. All three turbines were manufactured by Siemens . The gas turbines are fired with natural gas from the Hassi R'Mel gas field . The waste heat from the gas turbines is fed to the steam turbine together with the solar heat made usable by the collector field during the day. The waste heat from the steam turbine is dissipated via dry- cooled air condensers . The configuration used in the Hassi R'Mel power plant is referred to as Integrated solar combined-cycle (ISCC). Three more power plants of this type with a capacity of 400 MW (of which 70 and 80 MW solar) have been announced.
