Dubai’s Hatta pumped-storage hydroelectric plant begins testing, marking a significant step toward achieving the UAE’s net-zero ambitions with a 250 MW capacity and advanced energy storage methods.
The Dubai Electricity and Water Authority, known as DEWA, has kicked off testing and electricity exporting from its famous pumped-storage hydroelectric power plant in Hatta. This marks a pretty big milestone for the UAE’s push towards cleaner energy. HE Saeed Mohammed Al Tayer, the MD and CEO of DEWA, announced that this project is among the largest and most sophisticated renewable energy storage sites in the Gulf Cooperation Council (GCC) region. It’s got a capacity of 250 MW and can store up to 1,500 MWh of energy. During its testing phase, the plant has already produced more than 17,921 MWh of electricity.
Situated in Hatta, the plant was built with a clear eye on supporting Dubai’s ambitious clean energy goals outlined in the Dubai Clean Energy Strategy 2050 and the Net-Zero Carbon Emissions Strategy 2050. Basically, these initiatives aim for Dubai to run entirely on clean energy sources by mid-century. The hydro plant is expected to have a lifespan of up to 80 years, making it a long-lasting cornerstone for Dubai’s energy infrastructure.
This plant serves both local and regional energy needs. Hatta’s peak electricity demand is roughly 39 MW, and the excess energy generated gets exported to Dubai. Its strategic location close to Dubai allows it to respond super quickly—power can be sent to the grid within just 90 seconds—to meet peak demands. That definitely boosts the city’s energy system’s resilience.
One of the really impressive engineering feats here is the underground power station, built 60 metres beneath the ground. During his recent site visit, Al Tayer checked out two massive water valves—each weighing about 110 tonnes—and also toured the command and control room managing the plant’s operations. The infrastructure also includes an upper dam covering an area of 210,000 square metres. This dam has two concrete walls: a main wall that’s 72 metres high and 225 metres long, plus a side wall that’s 37 metres high. The reservoir holds around 5.3 million cubic metres of water, providing substantial energy storage capacity.
The plant works on pumped-storage hydroelectricity—basically, storing excess energy by pumping water up into a higher reservoir during times when electricity demand is low. When needed, water is released down through a 1.2-kilometre tunnel, spinning turbines and generating electricity. The efficiency of this whole process comes in at about 78.9%, meaning most of the stored energy can be effectively converted back into power when needed. Pretty handy, right?
A key part of the plant’s sustainability is how it works closely with the Mohammed bin Rashid Al Maktoum Solar Park. Solar power generated there helps pump water back to the upper dam—so it’s a cycle. The electrical energy from the sun is turned into stored hydrodynamic and gravitational energy, ready to be unleashed when required. That cyclical process isn’t just about generating power; it’s about storing renewable energy in a smart, long-term way.
Additionally, the Hatta hydro plant fits into DEWA’s broader strategy of diversifying its clean energy methods. Alongside advanced solar panels, concentrated solar power, and battery storage, this hydro project helps Dubai build a flexible, resilient, and sustainable energy network. The entire project cost around AED 1.42 billion and is expected to operate for many decades—showing Dubai’s strong commitment to green energy innovation.
Looking back at its development, the project has progressed quickly. From only about 35% completed in early 2022, it reached over 94% by late 2024. Generator installation and final testing are now underway, with full operation targeted for the first quarter of 2025. That rapid development really reflects DEWA’s dedication to delivering major infrastructure projects on schedule and within budget.
On a global scale, pumped-storage hydroelectricity is widely recognized as a reliable technology to stabilize power grids and integrate renewable sources like solar and wind—especially as these variable resources become more central. It’s pretty interesting, though, that DEWA is pioneering such a plant in the Arabian Peninsula, an arid region not commonly associated with hydroelectric power. This sets a new precedent in innovation and sustainability.
Saeed Mohammed Al Tayer highlighted during his visit that the project aligns perfectly with the vision of HH Sheikh Mohammed bin Rashid Al Maktoum, UAE’s Vice President and Prime Minister, as well as Dubai’s leadership. It’s a significant step forward in Dubai’s overall sustainable development goals, moving the city toward smarter, cleaner energy solutions.
In summary, the Hatta pumped-storage hydroelectric plant is a major milestone in Dubai’s clean energy journey. It boosts energy security, enhances grid flexibility, and brings cutting-edge tech into play—all within an environmentally conscious framework. With trial operations underway, this plant is set to become a key part of the UAE’s green energy future—helping the nation reach its goal of net-zero carbon emissions by 2050.
