Solar Thermal Electricity (STE)
Page 3: Ouarzazate (Morocco)
Two solar trough plants at Ouarzazate, Morocco, referred to as Noor I and Noor II, are now generating 360 MW of electricity. Noor I generates 160 MW, and Noor II generates 200 MW. Both power plants are adjacent to each other. All photographs on this page are of those two solar trough plants at Ouarzazate, Morocco.

Morocco is part of the Sahara Desert, which is well suited for siting of solar trough electricity generating power plants. Morocco is the country in the upper left corner of Africa:
Figure 3.15 Mediterranean and North Africa (MENA) countries. Yellow areas have higher direct normal irradiance (DNI) suitable for siting of solar trough power plants. Only a fraction of that area would be enough to provide all global or European electricity needs. [DLR]
Figure 3.16 Desertec map showing where solar trough power plants (concentrated solar power CSP) can be located, connected to Europe with high voltage direct current (HVDC
) transmission lines. Red square labelled World 2005 indicates how much land area (square kilometers) CSP would need to provide all of the world's electricity (at 2005 usage), EU-25 to provide just Europe's electricity, etc. [Desertec 2005]
