Coupling Power generation with thermal and RO desal plants
The combination of power and water generation systems results from a production cost optimisation by the investor. In some countries, this optimisation is difficult to make due to large variation of power demand between summer and winter. Whereas water demand remains steady all year long, power demand may vary from 100% in summer to 30% in winter due to air conditionning systems power consumption.
The following table explains the interest of the hybrid plant:
