Royers Lock Antwerp

At the Royers Lock in the Port of Antwerp, CIT Blaton, together with Artes Group, Boskalis and Stadsbader Group, is working on the complete modernization of the lock complex-one of the largest hydraulic engineering projects in the country.

As part of the Oosterweel connection, the old 1907 barge lock is to be replaced. The current lock will be replaced by a new lock with a length of 230 meters and a width of 36 meters, suitable for four-barge push navigation with more capacity and less traffic disruption.

‍Neargrid provides CIT Blaton 's construction site with reliable, quiet and emission-free energy. Two Boost 120 systems provide full power for five Liebherr tower cranes and all site equipment.

A powerful solution that eliminates fuel consumption and emissions, contributing to the future of sustainable water construction.

The challenge

The construction site has five Liebherr tower cranes and multiple energy-intensive installations that generate high power peaks.
The existing grid connection did not offer sufficient capacity to handle this load.
A traditional solution with multiple diesel generators would lead to noise pollution, higher emissions and fuel consumption,
while CIT Blaton net is committed to sustainability and energy efficiency.‍

‍

The goal

The project team sought a solution that:

• stable power supply guarantees for all tower cranes,
• drastically reduces CO₂ emissions and fuel dependence,
• while providing operational security even with varying load or low grid capacity.

The energy solution had to be flexible: providing sufficient power at peak loads,
but also operating efficiently during quiet periods with minimal emissions and maintenance.

‍

The solution

Neargrid supplied two Boost 120 systems that combine with a low-power generator to form a hybrid power system.
The generator provides a limited continuous supply, while the Boosts capture peak power and stabilize the system autonomously.

During low-load periods, the Boosts run fully electric, greatly reducing fuel consumption and noise levels.
The Boost units locally provide the power for the five Liebherr tower cranes and the supporting yard equipment, with real-time monitoring and automatic power control for optimal efficiency.

The result

The hybrid Boost configuration combines power, efficiency and sustainability on a complex water construction site.
A quiet, smart and scalable solution that allows CIT Blaton to build with energy security as well as a lower carbon footprint.
