Morocco’s king will switch on the first phase of a concentrated solar power plant on Thursday that will become the world’s largest when completed.
The power station on the edge of the Saharan desert will be the size of the country’s capital city by the time it is finished in 2018, and provide electricity for 1.1 million people.
Noor 1, the first section at the town of Ouarzazate, provides 160 megawatts (MW) of the ultimate 580MW capacity, helping Morocco to save hundreds of thousands of tonnes of carbon emissions per year.

What is a CSP or concentrated solar power?
CSP is used to produce electricity (sometimes called solar thermoelectricity, usually generated through steam). Concentrated-solar technology systems use mirrors or lenses with tracking systems to focus a large area of sunlight onto a small area. The concentrated light is then used as heat or as a heat source for a conventional power plant (solar thermoelectricity). The solar concentrators used in CSP systems can often also be used to provide industrial process heating or cooling, such as in solar air-conditioning.
Concentrating technologies exist in five common forms, namely parabolic trough, enclosed trough, dish Stirlings, concentrating linear Fresnel reflector, and solar power tower. Although simple, these solar concentrators are quite far from the theoretical maximum concentration. For example, the parabolic-trough concentration gives about 1/3 of the theoretical maximum for the design acceptance angle, that is, for the same overall tolerances for the system. Approaching the theoretical maximum may be achieved by using more elaborate concentrators based on nonimaging optics.
Different types of concentrators produce different peak temperatures and correspondingly varying thermodynamic efficiencies, due to differences in the way that they track the sun and focus light. New innovations in CSP technology are leading systems to become more and more cost-effective.
Commercial applications of Concentrated Solar Power
CSP is being widely commercialized and the CSP market has seen about 740 megawatt (MW) of generating capacity added between 2007 and the end of 2010. More than half of this (about 478 MW) was installed during 2010, bringing the global total to 1095 MW. Spain added 400 MW in 2010, taking the global lead with a total of 632 MW, while the US ended the year with 509 MW after adding 78 MW, including two fossil–CSP hybrid plants. The Middle East is also ramping up their plans to install CSP based projects and as a part of that Plan, Shams-I which was the largest CSP Project in the world has been installed in Abu Dhabi, by Masdar. The largest CSP project in the world until January 2016 is Noor in Morocco.
There is considerable academic and commercial interest internationally in a new form of CSP, called STEM, for off-grid applications to produce 24 hour industrial scale power for mining sites and remote communities in Italy, other parts of Europe, Australia, Asia, North Africa and Latin America. STEM uses fluidized silica sand as a thermal storage and heat transfer medium for CSP systems. It has been developed by Salerno-based Magaldi Industries. The first commercial application of STEM will take place in Sicily from 2015.
CSP growth is expected to continue at a fast pace. As of January 2014, Spain had a total capacity of 2,300 MW making this country the world leader in CSP. Interest is also notable in North Africa and the Middle East, as well as India and China. The global market has been dominated by parabolic-trough plants, which account for 90% of CSP plants.
