DUBAI 18 August 2019: Dubai Electricity and Water Authority (Dewa), has awarded Strabag Dubai, Strabag AG, Andritz Hydro and Ozkar consortium the construction contract for the Dh1.437 billion pumped-storage hydroelectric power station at Hatta.
The project is first of its kind in the Gulf and will generate 250 MW. The project is expected to last up to 80 years and is scheduled to be commissioned by February 2024. EDF has been appointed the consultant for this project.
This strategic project will diversify the energy mix, and support the economic, social and environmental development of Hatta. It will also achieve the goals of the Dubai Clean Energy 2050 to provide 75% of Dubai’s total power output from clean energy by 2050.
The hydroelectric power station will use the water in the Hatta Dam, stored in an upper reservoir that will be built in the mountain. Turbines that use clean and cheap solar power from the Mohammed bin Rashid Al Maktoum Solar Park to pump water from the dam to the upper reservoir.
The waterfall from the upper reservoir will generate electricity using turbines when required. The efficiency of the power generation and storage cycle will reach 80% within 90 seconds of the response to demand for electricity.
