DEWA awards AED 1.437 billion contract for 250-MW pumped storage station in Hatta

Dubai Electricity and Water Authority (DEWA) has awarded an AED1.437 billion (US$391.3 million) construction contract for the 250-MW Hatta pumped-storage hydroelectric power station to a consortium of Strabag Dubai LLC, Strabag AG, Andritz Hydro and Ozkar.

According to DEWA, this is part of the Comprehensive Development Plan for Hatta, launched by His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the United Arab Emirates and Ruler of Dubai.

The project is the first of its kind in the Arabian Gulf, DEWA says. It 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 project will diversify the energy mix and support the economic, social and environmental development of Hatta. It will also achieve the goals of Dubai Clean Energy 2050 to provide 75% of Dubai’s total power output from clean energy by 2050.

DEWA will provide job opportunities for UAE nationals to support the Hatta Comprehensive Development Plan. These include positions at the Visitor Centre and other outdoor activities and tourist facilities associated with the project. This supports the sustainable development of Hatta to make it one of the most prominent tourist attractions in the Emirate, DEWA says.

“This AED 1.437 billion pumped-storage hydroelectric power station project is part of our efforts, initiatives, and plans to achieve the vision of HH Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai,” said HE Saeed Mohammed Al Tayer, managing director and chief executive officer of DEWA. “DEWA’s strategy supports the UAE Centennial 2071, the UAE Vision 2021, and the Dubai Plan 2021 to ensure a sustainable, happy future and support the UAE’s aim to become first in everything.

“We are committed to supporting sustainable development, conserving natural resources and achieving economic, social and environmental development, in line with the aspirations of good leadership. Our use of hydroelectricity is part of our drive to achieve the objectives of the Dubai Clean Energy Strategy 2050, to transform the Emirate into a global hub for clean energy and green economy, and to increase the share of clean energy mix in Dubai to 75% by 2050.”

The hydroelectric power station will use the water in Hatta Dam as the lower reservoir, with a new upper reservoir to will be built in the mountain. The turbines will use solar power from the Mohammed bin Rashid Al Maktoum Solar Park to pump water to the upper reservoir. The efficiency of the power generation and storage cycle will reach 80% within 90 seconds of the response to demand for electricity.
