Construction of the first pumped storage plant in Dubai is 35% complete, the Dubai Electricity and Water Authority (DEWA) has announced.

The 1200m water high pressure tunnel has been completed at the 250MW Hatta plant, with the first 37m high Roller Compacted Concrete (RCC) wall also complete at the project’s upper dam, Saeed Mohammed Al Tayer, MD & CEO of DEWA said.

The Hatta plant, which has had investment of around AED 1.421 billion, is the first of its kind in the Gulf region. It will have a storage capacity of 1500MWh and a lifespan of up to 80 years. 

Al Tayer noted that the plant is part of DEWA’s efforts to diversify Dubai’s clean and renewable energy sources to include all available technologies such as solar photovoltaic panels, Concentrated Solar Power, green hydrogen production using solar power, pumped-storage water technology, and studying electricity generation from wind power in Hatta.

Al Tayer confirmed that the construction of the hydroelectric power plant uses the latest and safest drilling technologies suited to Hatta’s geological features and adheres to the strictest international environmental standards to protect the Hatta Natural Reserve.
