Concentrating Solar Power (CSP)
Concentrating Solar Power (CSP) uses mirrors to concentrate a large area of sunlight, onto a small area. Electrical power is produced when the concentrated light is converted to heat which drives a generator.
In virtually all applications CSP is large power, on the order of 100 MW or larger, that is used by utilities to generate electricity and distribute to consumers. In a CSP plant, solar energy is converted to heat and the heat is used in a conventional power cycle or other heat engine to produce mechanical power and drive a generator.
This unique facility provides experimental engineering data for the design, construction, and operation of unique components and systems in proposed solar thermal electrical plants; planned for large-scale power generation. At 200 feet tall, the NSTTF’s distinct height advantage along with its heat capabilities, offers a unique and complete testing environment to government contractors and agencies, research institutes, universities and private companies.
