How many solar trough power plants are there?

Since 2007, around 100 or more of commercial solar trough power plants have been built. The largest concentration of these is in Spain. Many of these installations are around 50 MW in generating capacity and a number include some form of energy storage.

What is a parabolic trough power plant?

Parabolic trough power plants use a curved, mirrored trough which reflects the direct solar radiation onto a glass tube containing a fluid (also called a receiver, absorber or collector) running the length of the trough, positioned at the focal point of the reflectors. The trough is parabolic along one axis and linear in the orthogonal axis.

Can a solar trough power plant operate 24 hours a day?

In principle a plant could be designed to operate 24 hours each day, but generally they are designed to be capable of supplying power during the main periods of grid demand rather than continuously. Since 2007, around 100 or more of commercial solar trough power plants have been built. The largest concentration of these is in Spain.
