TUI inaugurates 1,358 solar panels on Zaventem headquarters

International

New rooftop installation covers over half of the building’s annual electricity needs with locally generated green energy

TUI has officially inaugurated a major solar installation consisting of 1,358 panels on the roof of its headquarters in Zaventem. Developed in collaboration with Eneco Solar, the project represents another significant milestone in the group’s sustainability strategy. The new solar array will now provide more than 50% of the site’s annual electricity consumption, powered entirely by renewable energy produced on-site.

A unique project within the Brussels Airport zone

The installation is a technical first within the Brussels Airport perimeter, where strict aviation safety and visibility requirements pose major challenges for solar projects. Before installation, extensive analyses were conducted, including a structural stability study of the hangar, roof and energy yield assessments, and adjustments to the lightning protection system.

Due to its airport location, the project required approvals from multiple authorities, including Brussels Airport Company, skeyes (air traffic control), the fire department, and the grid operator. Following a glare study to ensure pilot safety, low-reflective solar panels were selected to comply with aviation standards.

Exceptional energy performance

The solar park features 1,358 panels, each with a capacity of 640 Wp, for an expected annual production of around 800 MWh – equivalent to the yearly electricity use of 230 Belgian households.

This renewable energy now supplies 53% of TUI’s total electricity consumption at its Zaventem headquarters. About 70% of the generated power is used directly on-site, with the remainder fed into the grid. The installation powers TUI’s Engineering & Maintenance hangar, the central hub for fleet maintenance and technical support for TUI fly Belgium and other group airlines.

A milestone for sustainable innovation

The inauguration event, held at TUI’s Zaventem headquarters, was attended by Thomas Ellerbeck, Member of the Group Executive Committee and Chief Sustainability Officer of TUI Group; Gunther Hofman, Managing Director of TUI fly Belgium/Netherlands; and Paul Minjauw, Managing Director of Eneco Solar.

Guests took part in a project presentation, a rooftop tour of the solar installation, and a guided visit to the Engineering & Maintenance hangar.

Thomas Ellerbeck stated:

“By generating renewable energy on our own site, we not only reduce our ecological footprint but also demonstrate that innovation and responsibility go hand in hand – even in a complex airport environment. Sustainability is part of our DNA at TUI, and we continue to see opportunities in sustainable tourism rather than challenges.”

Paul Minjauw added:

“This project proves that sustainable energy is possible in places where it once seemed impossible. Together with TUI, we’ve implemented an innovative solution that not only generates energy but also inspires. Everyone knows TUI as the company that takes people to the sun – from today, we are also bringing the sun to them.”
