The Crescent Dunes Solar Energy Plant near Tonopah in Nevada, USA is one of the largest stationery energy plants in the world. Being the most advanced energy storage project to this day, it is at the forefront of the clean energy industry in the USA as well as in the world. Although the Crescent Dunes became operational in September 2015, the Spaceknow technology enables users to observe its construction during key stages of the project between 2010 and 2015.
A satellite image from September 2010 shows the Crescent Dunes Project at its very beginnings. One can see that the site is fully under construction. There are numerous cars parked next to the construction site, three cranes are working on construction of the solar power tower and two trucks are approaching the site from the west.
In a satellite image from August 2013 one can see that the construction of the Crescent Dunes is in its final phase. A 165 m tall solar power tower in the centre is now completed and storage tanks show traces of finishing works on the roof. According to the image, the main focus is visibly put on the construction of put on the construction of a concentric field of 10,347 heliostat mirrors that is set to surround the solar power tower.
As the main construction works terminated at the end of 2013, the next satellite image from March 2014 shows the Crescent Dunes in the commissioning phase. However, the field of heliostat mirrors is not finished yet as one can vehicles next to some mirrors as well as a temporary facility in the middle of the field.
Although the Crescent Dunes started producing electricity in fall 2015, the last image from February 2015 shows that the plant is almost completed. The temporary facility in the north is gone and the field of heliostat mirrors is now fully constructed.
