Sector: 

New desalination plants being built in the UAE utilize the latest high efficiency electricity and water generation technology in order to maximize energy utilization.  Modern cogeneration plants built mainly over the last decade provide the base load capacity for power and water production.  In these plants, “waste” heat from gas turbines used for electricity generation is used to produce potablewater as part of the multistage flash (MSF) or multiple effect (MED) distillation processes, enabling fuel utilization efficiencies of over 80%.  Cogeneration plants are supplemented by highly efficient Combined Cycle Gas Turbine plants, such as the recently approved 1500MW phase 3 project at Schuweihat and others, such as the hybrid plants at Qidfa in Fujairah, which use a combination of  MSF/MED and reverse osmosis water production technologies to optimize annual thermal efficiencies.
