Hydroelectric Power Plant in Hatta

The pumped-storage hydroelectric power plant in Hatta is considered one of the most important projects implemented by the Authority, in line with the vision and directives of His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President, Prime Minister, and Ruler of Dubai, may God protect him. The project aims to achieve comprehensive and sustainable development across the Emirate of Dubai and supports the Dubai Clean Energy Strategy 2050 and the Dubai Net Zero Carbon Emissions Strategy 2050, with the goal of providing 100% of Dubai’s total power production capacity from clean energy sources by 2050.

The plant will have a production capacity of 250 megawatts, with a storage capacity of up to 1,500 megawatt-hours and an operational lifespan of up to 80 years. The total investment in the project is approximately AED 1.42 billion.

The storage capacity of the upper dam, built by DEWA as part of the project, is around 5.3 million cubic meters (1,166 million gallons) of water, with a total water surface area of around 210,000 square meters. The dam comprises two compressed concrete walls: a main wall 72 metres high and 225 metres long, and a side wall 37 metres high.

The project is designed to generate electricity using water stored in the Hatta Dam and the upper dam with a turnaround efficiency of 78.9%. It uses the potential energy of water stored in the upper dam, converting it into kinetic energy as it flows through a 1.2-kilometre subterranean tunnel. This kinetic energy rotates the turbines, converting mechanical energy into electrical energy, which can be supplied to DEWA’s grid within 90 seconds to meet demand. To store energy, clean power generated at the Mohammed bin Rashid Al Maktoum Solar Park will be used to pump water back to the upper dam, converting electrical power into kinetic energy in the process.
