EDF wins contract from DEWA for250MW hydroelectric power station
France-based EDF has secured a contract from Dubai Electricity and Water Authority (DEWA) to provide consultancy services for a new 250MW pumped-storage hydroelectric power station at Hatta Dam in the United Arab Emirates.
The AED58m ($15.7m) deal will provide DEWA with consultancy on deep-water tunnel designs and tender for material supply. It also includes hydro-geological, geological, environmental, geotechnical, and deep excavation studies.
EDF will be responsible for supervision of construction work, site installation, on-site testing, and commissioning.
DEWA's managing director and chief executive officer (CEO) Saeed Mohammed Al Tayer said: “The hydroelectric plant costs AED1.92bn ($522m).
“It is part of the Hatta Comprehensive Development Plan, launched by His Highness Sheikh Mohammed bin Rashid Al Maktoum, vice-president, and Prime Minister of the UAE, and Ruler of Dubai.
“We are working to achieve the UAE Vision 2021 to make the UAE one of the best countries in the world by 2021, supporting sustainable development, preserving natural resources, and achieving economic, social, and environmental development in line with the aspirations of our wise leadership.”
DEWA’s new hydroelectric power station is expected to remain functional for 60 to 80 years. The facility will use water stored in the Hatta Dam. An upper reservoir will also be built 300m above the dam to store up to 880 million gallons of water.
During off-peak hours, turbines run on clean and inexpensive solar energy will pump water from the lower dam to the upper reservoir. During peak-load hours, the water will be moved down through the turbines to generate electricity and connect it to DEWA’s grid.
