The recent announcement that Xcel Energy has signed a 20-year contract with Cogentrix Energy for a new concentrating solar power facility to be built in the San Luis Valley is indicative of a trend. CSP projects are becoming a more considered means of generating power from solar energy. The primary plant designs are solar trough, linear Fresnel and power tower plants. All three of these technologies use mirror configurations to concentrate a large area of sunlight onto a small area.
