Dubai has officially inaugurated the fourth phase of the Mohammed bin Rashid Al Maktoum Solar Park, marking a major step forward in global renewable energy development. The project was launched during the COP28 climate summit and highlights the UAE’s growing focus on clean and sustainable energy solutions. With a total capacity of 950 MW, the project represents an investment of AED 15.78 billion and strengthens Dubai’s position as one of the world’s leaders in large-scale solar infrastructure.
This phase of the solar park stands out because it combines three different solar technologies within a single project. It includes 600 MW generated from a parabolic basin complex, 100 MW from a concentrated solar power tower, and 250 MW from photovoltaic solar panels. The integration of these technologies allows the plant to deliver stable and reliable power while maximizing energy efficiency.
The project has also achieved global recognition by securing two Guinness World Records. It is home to the world’s tallest solar tower, measuring 263.126 meters, and features the largest thermal energy storage capacity ever built, at 5,907 megawatt hours. These records underline the scale and technical ambition of the project.
Spread across an area of 44 square kilometers, the site uses around 70,000 heliostats. These mirrors track the movement of the sun and reflect sunlight toward a Molten Salt Receiver located at the top of the central tower. The receiver is made up of more than 1,000 thin tubes that absorb solar radiation and heat molten salt flowing through them.
The heated molten salt acts as a thermal energy reservoir, enabling electricity generation even after sunset. This capability ensures a continuous power supply and supports grid stability. Overall, the project demonstrates how advanced solar technologies can play a key role in meeting energy demand while reducing carbon emissions.
