The CSP polygeneration plant model of 50 MWe can provide electricity and freshwater to more than 85,000 inhabitants.
The optimum configuration for the polygeneration plant is achieved for a water production of 20.000–30.000 m3/day.
A 15% reduction of the PTC initial investment cost could result in competitive costs in the northern Chile market.
In Venezuela, a CSP polygeneration could be possible alternative with a 25% reduction of PTC initial investment cost.
