Dubai Electricity and Water Authority (DEWA) has announced the beginning of trials that will export electricity to Dubai from Hatta’s hydroelectric power plant. The final stages of work on the distribution link are now underway, the utility firm said.
The initiative was officially announced during the visit of Saeed Mohammed Al Tayer, Managing Director & CEO, DEWA to review the project’s progress. In the final stages of testing, the amount of energy produced by the hydroelectric plant exceeded 17,921 megawatt-hours.
When completed, the plant will have a production capacity of 250MW, a storage capacity of 1,500MWh and a lifespan of up to 80 years. The peak electricity demand in Hatta is approximately 39MW and the surplus will be exported to Dubai, DEWA explained.
The initiative supports the Dubai Clean Energy Strategy 2050 and the Dubai Net-Zero Carbon Emissions Strategy 2050, which aim to provide 100% of Dubai’s total energy production capacity from clean sources by 2050.
The official visit included a tour and inspection of the upper dam, built by DEWA as part of the project, which has a total water surface area of 210,000sqm. The dam is constructed from two compressed concrete walls: a main wall 72m high and 225m long, and a 37m-high side wall. The upper dam has a storage capacity of around 5.3mn cu/m (1,166m gallons) of water.
The dam plays a crucial role in the project, since the hydroelectric process uses the potential energy of water stored in the upper dam, converting it into kinetic energy as it flows through a 1.2km subterranean tunnel. This kinetic energy rotates the turbines, converting mechanical energy into electrical energy, which can be supplied to DEWA’s grid within 90 seconds.
Meanwhile, to store energy, clean power generated at the Mohammed bin Rashid Al Maktoum Solar Park will be used to pump water back to the upper dam, converting electrical power into kinetic energy in the process, DEWA explained.
