Dubai: Saeed Mohammed Al Tayer, MD and CEO of Dubai Electricity and Water Authority (DEWA) has disclosed that DEWA achieved a noteworthy accomplishment in enhancing the efficiency of power and water production with a 41.73 percent increase in 2023 over 2006. By planting 484 million trees to absorb this CO2 output, we may reduce carbon dioxide emissions by 92.5 million tons between 2006 and 2023.
“At DEWA, we are committed to achieving the vision and directives of His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President, Prime Minister and Ruler of Dubai, to consolidate Dubai’s position as a global hub for clean energy and a green economy. We emphasize enhancing energy and water production efficiency through innovation and continuous upgrades to our production plants, as well as deploying cutting-edge technologies across all our facilities and projects. These efforts have led to a 41.73 percent increase in electricity and water production efficiency in 2023 compared to 2006, resulting in significant reductions in carbon emissions and substantial financial savings,” said Al Tayer.
DEWA employs an innovative hybrid system for water desalination plants, integrating various technologies such as Multi-Stage Flashing (MSF) and Seawater Reverse Osmosis (SWRO), ensuring optimal efficiency throughout the plant’s lifecycle and minimizing costs.
The authority regularly develops operation and maintenance modes to enhance efficiency further. It also collaborates with original equipment manufacturers to undertake gas turbine upgrades, improving their efficiency, performance, and reliability.
Nasser Lootah, Executive Vice President of Generation (Power & Water) at DEWA, explained that DEWA produces electricity and water using co-generation technology. Heat Recovery Steam Generators (HRSG) harness waste heat from gas turbines to generate additional electricity and provide thermal energy for the water desalination process.
For water desalination facilities, DEWA uses a cutting-edge hybrid system that integrates many technologies, including Multi-Stage Flashing (MSF) and Seawater Reverse Osmosis (SWRO), to ensure maximum efficiency throughout the plant’s lifespan and save costs.
DEWA consistently innovates on modes of operation and maintenance to further improve efficiency. Additionally, it works with OEM manufacturers to modify gas turbines, enhancing their dependability, performance, and efficiency.
