Dewa's transmission investments surpass Dhs7.6 billion
He further noted that Dewa commissioned four 132 kV substations with a conversion capacity of 450 megavolt-amperes during the first half of 2025, at a cost of Dhs725 million. These projects included the extension of 228km of transmission cables.
Al Tayer explained that Dewa is currently building 49 new 132 kV substations and two 400 kV substations. Dewa also inviting main contractors to submit proposals for the implementation of 11 new 132 kV transmission substations.
Over the next three years, Dewa intends to issue new tenders to establish more than 57 additional 132 kV substations and to extend 160km of underground transmission cables.
Hussain Lootah, Executive Vice President of Transmission Power at Dewa, explained that the new substations serve different areas, including two in Al Yalayis 5 to meet the energy needs of citizens' housing projects, as well as substations in Hatta and Warsan 4.
He noted that the total number of Dewa's electricity transmission substations reached 391 by the end of the first half of 2025, including 27 substations at 400 kV and 364 at 132 kV.
The implementation and commissioning of these projects required more than 4.5 million working hours using the latest internationally approved digital technologies.
Dewa has awarded contracts to build 10 new 132 kV substations in several areas in Dubai, including Al Barsha South 2, Business Bay, Dubai Silicon Oasis, Airport City, Nad Al Sheba 1 and Wadi Al Safa 5, at a total cost of Dhs1.1 billion.
Dewa has also awarded projects to extend 132 kV cables to connect the new main substations to the main electricity transmission network, with a total length of 60.6km and a total cost of Dhs288 million.

Dubai's RTA opens new tunnel, reduces travel time to 3.8 minutes
Dubai's Roads and Transport Authority (RTA) has officially opened a new 800-metre tunnel with four lanes in each direction, designed to significantly improve traffic flow along Umm Suqeim Street. The tunnel forms a key part of the Umm Suqeim Street Development Project, which runs from the intersection with Al Khail Road to the junction with Sheikh Mohammed Bin Zayed Road. The upgraded road network is expected to benefit more than one million residents across several major communities, including Al Barsha South 1, 2, and 3, Dubai Hills, Arjan, and Dubai Science Park. "The project enhances connectivity between four strategic corridors in Dubai: Sheikh Zayed Road, Al Khail Road, Sheikh Mohammed Bin Zayed Road, and Emirates Road. It increases the capacity of Umm Suqeim Street to 16,000 vehicles per hour in both directions, improves traffic flow, and reduces travel time between Sheikh Mohammed Bin Zayed Road and Al Khail Road by 61% from 9.7 minutes to 3.8 minutes," said Mattar Al Tayer, Director General and Chairman of the Board of Executive Directors at RTA. Al Tayer also noted that RTA employed advanced smart technologies throughout the project. Drones equipped with artificial intelligence (AI) were used to collect and analyse construction data in real time, enhancing decision-making, boosting site efficiency, and reducing field survey time by 60%. "Additionally, time-lapse imaging was employed to continuously track construction progress, increasing monitoring efficiency by 40%," he said. The current development builds on earlier phases of the project. In 2013, RTA completed Phase I, which covered the section from Sheikh Zayed Road to Al Khail Road. This phase included the construction of two bridges, each comprising three lanes in both directions, the first crossing the eastern street parallel to Al Asayel Street, and the second crossing the western street parallel to First Al Khail Road. The phase also included the development of two signalised intersections at the intersections of Umm Suqeim Street with Al Asayel Street and First Al Khail Road, in addition to three pedestrian bridges along Umm Suqeim Street to ensure safe crossing between Al Quoz and Al Barsha areas. In 2020, RTA also completed a 500-metre bridge at the intersection of Umm Suqeim Street and the entrance to Dubai Hills and Al Barsha South, as part of infrastructure upgrades for Dubai Hills Mall. This bridge features four lanes in each direction and handles up to 16,000 vehicles per hour-matching the capacity of the newly opened tunnel. WAM
