DEWA reduces CO2 emissions with increased electricity, water efficiency

Dubai Electricity and Water Authority (DEWA) improved its water and electricity efficiency by 43.61 per cent in 2024, resulting in a cumulative reduction of 104 million tonnes of carbon dioxide (CO2) emissions since 2006.

The 104 million-tonne CO2 reduction is the equivalent to planting 527 million trees to absorb this amount of CO2.

MD & CEO of DEWA, Saeed Mohammed Al Tayer noted that this improvement in electricity and water production efficiency contributed to DEWA's achievement of substantial financial savings.

Nasser Lootah, Executive Vice President of Generation (Power & Water) at DEWA, said, “We place great emphasis on enhancing the efficiency of electricity and water production through innovation and continuous upgrades to our production plants, as well as the deployment of cutting-edge technologies across all our facilities and projects. DEWA regularly develops operation and maintenance modes to enhance efficiency further.”

DEWA produces electricity and water using co-generation technology. Heat recovery steam generators harness waste heat from gas turbines to generate additional electricity and provide thermal energy for the water desalination process.

DEWA employs an innovative hybrid system for water desalination plants, integrating various technologies such as multi-stage flashing and seawater reverse osmosis, ensuring optimal efficiency throughout the plant’s lifecycle and minimising costs.
