Dubai: The DEWA-built pumped-storage hydroelectric power plant site in Hatta is 58.48 percent finished. With up to USD 386 million in investments, this station is the first of its kind in the GCC. The project is anticipated to be finished in Q4 2024.
The power plant will have a production capacity of 250 megawatts (MW), a storage capacity of 1,500 megawatt-hours and a life span of up to 80 years. The project is planned for completion in the 4th quarter of 2024.
Mr. Saeed Mohammed Al Tayer, MD & CEO of Dubai Electricity and Water Authority (DEWA), has visited the power plant site to check the work progress. During the visit, Mr. Al Tayer was accompanied by Mr. Nasser Lootah, Executive Vice President of Generation, Mr. Mansoor Al Suwaidi, Vice President – Projects and Engineering (Generation) and Mr. Khalifa Al Badwawi, Project Manager, along with the project team.
The CEO of DEWA inspected the construction site at the hydroelectric power plant, where he was briefed about the work progress. The visit also included the inspection of the power generators site and the upper dam, where the water intake in the Hatta Dam connected to the power generators has been completed. Construction of the 72-metre main Roller Compacted Concrete (RCC) wall of the upper dam has been completed. Mr. Al Tayer also inspected the work progress of the water tunnel, which is 1.2 kilometres long and connects the two dams. The concrete lining of the water tunnel is complete.
Mr. Al Tayer stated that the power plant is part of DEWA’s efforts to achieve the Dubai Clean Energy Strategy 2050 and the Dubai Net Zero Carbon Emissions Strategy 2050 to provide 100 percent of Dubai’s total power production capacity from clean energy sources by 2050. The project supports the comprehensive plan to develop Hatta and meet its social, economic, developmental and environmental needs, in addition to providing innovative job opportunities for citizens in Hatta.
The CEO further added that the hydroelectric power plant in Hatta is part of the projects and initiatives launched by DEWA to diversify energy production from renewable and clean sources in Dubai. These include different available technologies such as solar photovoltaic panels, concentrated solar power, and green hydrogen production using renewable energy.
The Hydroelectric power plant will be an energy storage facility with a turnaround efficiency of 78.9 percent that utilises the water stored in the upper dam, which is converted to kinetic energy during the flow of water through the 1.2-kilometre subterranean tunnel.
This kinetic energy rotates the turbines and converts mechanical energy to electrical energy which is sent to DEWA’s grid within 90 seconds in response to demand. To store energy, clean energy generated at the Mohammed bin Rashid Al Maktoum Solar Park will be used to pump the water through this tunnel back to the upper dam by converting the electrical power to kinetic energy making the whole project 100 percent renewable.
