The Dubai Electricity and Water Authority (DEWA) reported that the completion rate of the hydroelectric plant with stored hydropower technology in Hatta has reached 29%, while the plant's production capacity will reach 250 megawatts, with a storage capacity of 1,500 megawatts per hour and a lifespan of up to 80 years.

DEWA indicated in a statement yesterday that the new station is the first of its kind in the Arab Gulf region, indicating that the project's investments amount to one billion and 421 million dirhams.

The authority stated that the Managing Director and CEO of DEWA, ​​Saeed Mohammed Al Tayer, visited the site of the construction works at the station, during a tour of the project, where he listened to a detailed explanation of the progress of the project.

The visit also included an inspection of the construction works of the upper dam of the project, as the construction of the first wall of the upper dam, with a height of 37 meters of compressed concrete, was completed.

In the production of electricity, the hydroelectric station will depend on making use of the water stored in the Hatta Dam, and another upper dam being built in the mountainous region.

reverse method

Advanced turbines that rely on clean energy produced in the Mohammed bin Rashid Al Maktoum Solar Energy Complex will work in reverse, to pump water from the Hatta Dam to the upper dam, and when needed, these turbines will be operated to produce electricity and supply it to the Authority's network, by taking advantage of the power of the water rush. Sloping from the upper dam to the Hatta dam, by creating an underground water channel of up to 1.2 km in length, and the efficiency of the cycle of the electricity production and storage process will reach 78.9%, with an immediate response to energy demand within 90 seconds.

strategy

Al Tayer said: “We have a clear strategy and specific goals, by increasing reliance on renewable and clean energy within Dubai’s energy mix, as we work to achieve the Dubai Clean Energy Strategy 2050, with the aim of providing 75% of Dubai’s total energy production capacity from clean energy sources. by 2050.”

He added that "the hydroelectric plant project in the Hatta region is a continuation of the authority's efforts to diversify sources of energy production, which included all clean and renewable energy technologies in the Emirate of Dubai, such as photovoltaic panels technology, concentrated solar energy, green hydrogen production using renewable energy, and a study of the electricity generation project, from By benefiting from wind energy in Hatta, the project also falls within the initiatives adopted by the authority aimed at providing innovative job opportunities for citizens in Hatta, in addition to developing the region and meeting its development, social, economic and environmental needs.”

Construction works

Saeed Al Tayer, Managing Director and CEO of Dubai Electricity and Water Authority, said: “The construction work at the hydroelectric station includes the use of the latest innovative methods in drilling techniques, the most advanced and safest, to suit the geological conditions of the Hatta region, taking into account the highest international environmental standards to preserve the Hatta Mountain Reserve. ».

He explained that «the excavation of the service tunnels in the project, each of which is 500 meters long, has been completed, while more than 95% of the drilling operations have been completed for the 1.2-kilometre-long water tunnel, and the excavation work has been completed in the area where generators will be installed. It has a depth of up to 60 metres.

In the production of electricity, the station depends on making use of the water stored in the Hatta Dam and another upper dam.
