Dubai to Build World’s Largest Solar-Powered Desalination Plant for Sustainable Water Supply
Dubai is setting a new global benchmark in sustainable infrastructure with the construction of the world’s largest solar-powered desalination plant. The ambitious project, known as the Hassyan Desalination Plant, aims to produce clean drinking water for up to two million people every day — using nothing but the power of the sun.
Developed by the Dubai Electricity and Water Authority (DEWA) in collaboration with ACWA Power and Veolia, the facility will have a production capacity of 818,000 cubic meters of water per day once fully operational in 2027. Located about 55 kilometers southwest of Dubai Creek, the plant will play a vital role in supporting the city’s fast-growing population and its long-term sustainability goals.
At the heart of this innovative project lies advanced reverse osmosis technology, combined with highly energy-efficient systems that reduce power consumption by up to 35% compared to traditional desalination methods. Unlike conventional plants that rely on fossil fuels, the Hassyan facility will operate entirely on solar energy, making it a zero-emissions solution to one of the Middle East’s most pressing challenges — water scarcity.
The €848 million project is a key component of Dubai’s broader strategy to achieve carbon neutrality and secure sustainable water resources for decades to come. By merging renewable energy with essential public utilities, Dubai is demonstrating how cities in arid regions can address environmental and resource challenges through innovation and clean technology.
Once complete, the Hassyan Desalination Plant will not only strengthen Dubai’s water security but also stand as a global model for sustainable development, proving that clean energy and large-scale infrastructure can go hand in hand to build a greener future.
