Energy DEWA expects hydroelectric plant completion in Q4 2024 By Pramod Kumar December 27, 2022 WAM Dewa was listed as a public company on the Dubai Financial Market in April 2022 The pumped-storage hydroelectric power plant that Dubai Electricity and Water Authority (DEWA) is building in Hatta is 58.48 percent complete, state-run WAM news agency reported. This is the first station of its kind in the GCC, with investments of up to AED 1.421 billion ($387 million). The project is planned for completion in Q4 of 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. Saeed Mohammed Al Tayer, managing director and chief executive of DEWA, inspected the construction site at the hydroelectric power plant, including the power generators’ site and 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 wall of the upper dam has been completed. 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. He said 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 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.
