Kathu Solar Park

Kathu Solar Park is a 100 MW greenfield Concentrated Solar Power (CSP) project with parabolic trough technology and equipped with a molten salt storage system that allows 4.5 hours of thermal energy storage and thus limits the intermittent nature of solar energy. In short, it allows the opportunity to produce electricity even after the sun goes down.

The parabolic trough technology operates by tracking the sun with the parabolic reflectors and focusing the sun’s rays into an absorber pipe. The absorber pipe, which is seated above the mirror along the focal line, contains a heat absorbent medium that absorbs the energy. 

The heat absorbent material carries energy to water in a boiler heat exchanger and the heat is used to produce steam which drives a turbine.
