Dubai’s DEWA awards $15.8mn hydro power consultancy contract to EDF
DEWA said the consultancy contract covers design, hydro-geological, geological, environmental, geotechnical and deep excavation studies.
Dubai Electricity & Water Authority (DEWA) announced it has awarded a $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.
DEWA will build the hydroelectric power station to generate electricity by making use of the existing water stored in the Hatta Dam, which can store up to 1,716 million gallons, and an upper reservoir that will be built in the mountain that can store up to 880 million gallons. The upper reservoir will be 300 metres above the dam level. During off-peak hours, turbines that use clean and cheap solar energy will pump water from the lower dam to the upper reservoir.
During peak-load hours, when production costs are high, turbines operated by the speed of waterfall from the upper reservoir will be used to generate electricity and connect it to Dewa’s grid. The efficiency of power production will reach 90 per cent with a 90-second response to demand for electricity
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 $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.
