Concentrating Solar Power (CSP)

1. Smaller-scale, Low-Concentration-Ratio Systems

a. Back Reflector

Ref: www.fossilfreedom.com

b. Compound Parabolic Concentrator (CPC)

c. Plane Reflector

2. Larger, Higher-Concentration-Ratio systems

a. Parabolic Trough

www.solel.com

KJC (now Solel) Mojave Desert – 200 MWSolar Electric Generating System (SEGS)

2.3 million square meters of mirror surface area

Each collector: 25 ft high by 50 ft long To improve their performance they can be rotated about their roll

axis.

Fluid: synthetic oil; operating temperature: 400 ºC

WORLDS LARGEST SOLAR THERMAL POEWER PLANT

Also: Nevada One, Boulder City, CA: 64 MW plant (World’s 2nd Largest solar thermal plant)

Coming Soon (in 2011): Mojave Solar Park (553 MW). Will be world’s largest solar thermal power plant (to be built by Solel).

Coming Soon (in 2013): Kingman, Ariziona (340 MW) “Will be world’s largest” (assuming Mojave solar park falls through?

b. Compact Linear Fresnel Reflector (CLFR)

Liddel Solar Thermal Plant, Phase I (1 MW), New South Wales, Australia, built by Ausra (www.ausra.com), 2004.

Kimberlina Solar Thermal Energy Plant in Barstow, CA (5 MW). Also built by Ausra.

c. Parabolic Dish Reflector

**Stirling Energy Systems and utility Southern California Edison are building a 500-megawatt solar power plant to open in 2009. The plant will be the first commercial application of the Stirling Solar Dish. (source: geotimes.com)

Can also be used for concentrated PV systems (will ignore for now, since PV is not solar thermal).

d. Central Receiver Plant(AKA Heliostat Power Plant, Solar Power Tower)

Solar One: 1982-1986 (10 MW)Expanded into Solar Two: 1995-1999.

See a virtual field trip of Solar Two at http://www.ieesocal.org/review3.html.

Other Central Receiver Plants:

11 MW plant in Seville, Spain

Coming Soon (2011): Ivanpah, California (Mojave Desert) – 400 MW
