Dubai Electricity & Water Authority (DEWA) announced today it has awarded a US$15.8 million consultancy contract to France’s EDF for the US$523 million 250-MW pumped storage project at Hatta Dam, located in Dubai, United Arab Emirates.
DEWA said the consultancy contract covers design, hydro-geological, geological, environmental, geotechnical and deep excavation studies. It also includes 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.
The facility will generate electricity using water stored in Hatta Reservoir, which can store up to 1,716 million gallons, and an upper reservoir that will be built that can store up to 880 million gallons.
DEWA said the upper reservoir will be 300 meters above the dam level. During off-peak hours, turbines that use solar energy will pump water from the lower dam to the upper reservoir.
The facility, in the Hajar Mountains, plans to have a 90-second response time to begin generating energy to DEWA’s grid.
In November 2016, DEWA announced plans to construct the facility, which is expected to last 60 to 80 years.
The plant is part of the Hatta Comprehensive Development Plan, launched by His Highness Sheikh Mohammed bin Rashid Al Maktoum, vice president and prime minister of UAE and ruler of Dubai, according to HE Saeed Mohammed Al Tayer, DEWA managing director and chief executive officer.
The project will also create hydropower industry jobs in the UAE. Additionally, in January, HydroWorld.com reported the International Renewable Energy Agency and Abu Dhabi Fund for Development partnered to provide US$15 million to construct a hydroelectric plant in the Solomon Islands.
“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,” Al Tayer said.
