Project Completion Progress: 94.15% Done, Trial Operation Set for 2025
The Dubai Electricity and Water Authority (DEWA) has announced that its pumped-storage hydroelectric power plant in Hatta is now 94.15% complete, marking a significant milestone toward its full operational readiness. The facility, slated to begin trial operations in Q1 2025, is a cornerstone project for Dubai’s push to diversify its energy portfolio and achieve its ambitious Net Zero Carbon Emissions goals. Currently, the installation of generators is underway, alongside the final steps in dam filling. This plant is designed to be a highly efficient energy storage solution that will complement the city’s expanding renewable energy infrastructure.
Innovative Energy Storage and Conversion System
The Hatta pumped-storage hydroelectric power plant operates by storing potential energy in an upper dam. This water is then released through a 1.2-kilometer subterranean tunnel, which drives turbines that convert mechanical energy into electrical power. The system boasts an energy conversion efficiency of 78.9%. It will have a production capacity of 250 MW and a storage capacity of 1,500 megawatt-hours. The plant is designed to deliver power to the grid within 90 seconds of demand spikes, demonstrating its role as a rapid-response energy source.
Integration with Solar Power and Green Hydrogen
A key feature of the project is its integration with renewable energy. The energy generated by the Mohammed bin Rashid Al Maktoum Solar Park will be used to pump water back to the upper dam, storing excess solar energy as potential energy. This integration supports the wider vision of a clean energy ecosystem, where solar power helps drive energy storage that can be deployed when the grid needs it most. Additionally, the project’s alignment with green hydrogen production highlights DEWA’s strategy to foster hydrogen-based energy solutions in Dubai.
Strategic Milestone for Sustainable Development and Job Creation
The Hatta hydroelectric power plant is the first of its kind in the Arabian Gulf region, underscoring Dubai’s leadership in clean energy innovation. With a total investment of AED 1.421 billion, the plant will serve not only as a pioneering clean energy project but also as a significant contributor to local job creation, particularly for Emiratis. It will further support Dubai’s Clean Energy Strategy and contribute to the Dubai Net Zero Carbon Emissions Strategy 2050 by diversifying the energy mix and improving energy security.
Projected Timeline and Future Impact
Upon full completion in Q2 2025, the plant is expected to play a crucial role in Dubai’s renewable energy transition, helping to stabilize the grid and meet peak demand. With its long lifespan of up to 80 years, the plant is poised to contribute to Dubai’s sustainable energy infrastructure for decades to come. This project represents a critical step in DEWA’s broader vision for a sustainable future, with its blend of energy storage, renewable energy integration, and green hydrogen development setting a global example for the power industry.
