DEWA awards $15.8m Hatta consultancy contract to EDF
The contract, which is for the hydroelectric power station at Hatta Dam, covers design, hydro-geological, geological, environmental, geotechnical, and deep excavation studies
Dubai Electricity and Water Authority (DEWA) has announced awarding a consultancy contract valued at $15.8m (AED58m) to French company, EDF.
The contract, which is for the pumped-storage hydroelectric power station at Hatta Dam, covers design, hydro-geological, geological, environmental, geotechnical, and deep excavation studies, Dubai Media Office reported.
The contract terms also extend to consultancy on deep-water tunnel designs, the dam and hydroelectric power station, the tender for material supply, supervision of construction work, site installation, on-site testing, and commissioning.
HE Saeed Mohammed Al Tayer, managing director and CEO of DEWA, said: “The hydroelectric plant costs $522.7m (AED1.92bn). It is part of the Hatta Comprehensive Development Plan, launched by HH Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai.”
The power station project, with its total capacity of 250MW and a lifespan of 60 to 80 years, is reportedly the first of its kind in the region.
According to DEWA, it will implement the power station by utilising water stored in the Hatta Dam, which has a maximum capacity of 1,716 million gallons. The authority also has plans to draw water from an upper reservoir that it intends to build in the mountain, 300m above the dam level. The planned reservoir is expected to be able to store up to 880 million gallons.
DEWA explained that during off-peak hours, solar-powered turbines will pump water from the dam to the upper reservoir.
During peak-load hours, on the other hand, when production costs are high, turbines powered by the speed of waterfall from the upper reservoir will be used to generate electricity and will be connected to the grid.
DEWA is expecting the efficiency of power production to reach 90%, with a 90-second response to demand for electricity.
