The Sagrada Família Basilica in Barcelona has recently witnessed one of the most significant milestones in its history. On June 10, 2026, Pope Leo XIV officially inaugurated the Tower of Jesus Christ, the 18th and final tower of Antoni Gaudí’s masterpiece, bringing to completion a project that began more than 140 years ago.
Standing at 172.5 metres, the tower makes the Sagrada Família the tallest church in the world and marks the culmination of a vision that has transcended generations, becoming one of the most iconic symbols of architecture, engineering and cultural heritage worldwide.
Long before the inauguration ceremony, Grupel had the privilege of contributing to one of the most demanding phases of this extraordinary project.
To ensure uninterrupted operations during the construction of the Jesus Christ Tower, Grupel supplied an 880 kVA generator set designed to provide emergency power to the tower crane installed at the highest point of the basilica. At the time, it was one of the largest cranes ever used in a European construction project of this nature.
Operating in standby mode, the generator was engineered to automatically start in the event of a grid failure, ensuring the continuity and safety of construction activities throughout this critical stage of the project.
In a project of this scale, any power interruption could result in operational risks, costly delays and significant disruptions to construction schedules.
To address these challenges, the solution supplied by Grupel included a mains synchronization system capable of providing seamless load transfer, ensuring continuous power supply to the crane and associated equipment. The project also incorporated a 1,000-litre fuel tank, engine preheating system and several auxiliary components specifically selected to meet the demanding requirements of the site.
The completion of the Tower of Jesus Christ represents far more than the end of a construction project. It is the realization of a vision first conceived in 1882 and a milestone in the history of modern architecture.
Knowing that Grupel’s engineering and technology played a role in supporting this final phase of construction is a source of great pride for our team.
Because even when it remains behind the scenes, reliable power is often what makes the world’s most ambitious projects possible.
At Grupel, we believe reliability is measured by more than performance figures. It is measured by the confidence our customers place in every solution we deliver, especially when continuity is essential.
