House of the City in Amersfoort

Emission-free power supply for three Liebherr cranes on an inner-city construction site

The challenge

On the compact inner-city yard of the House of the City of Amersfoort, three Liebherr 280 EC-H tower cranes needed to be powered.
The available 80A grid connection did not provide sufficient power, while the cranes demand high peak loads during hoisting and slewing movements.
Additional grid reinforcement or diesel generators would lead to:

- higher costs,

- CO₂ and NOx emissions,

- noise and odor pollution,

AND risk of downtime.

The contractor needed a quiet, emission-free and highly reliable energy solution fully in line with the CO₂ Performance Ladder.

‍

The goal

- Electrically power all three Liebherr EC-H cranes without downtime

- Zero emission, even during peak power

- Stable voltage and grid quality in a tight inner-city context

- No heavy mains connection or diesel generators

- Direct contribution to higher CO₂ reduction scores for procurement and reporting

‍

The solution

Neargrid installed two Boost 200 systems that together form an intelligent microgrid at the site.

- Power supply via limited mains connection

- The Boost units provide all peak power for the three 280 EC-H valves

- 100% emission-free operation during lifting and slewing peaks

- Constant voltage quality → no shutdowns, no downtime

- Stable power supply for all supporting site consumers

- Real-time monitoring → insight, control and optimal efficiency

‍

The result

The combination of two Neargrid Boost 200 provided a continuous, quiet and emission-free power supply for all three tower cranes.

- 0 liters of diesel consumed

- No emissions, no disturbance to the environment

- Lower operating costs

- Complete operating reliability thanks to automatic peak-shaving

- Significant improvement in CO₂-Performanceladder scores

‍

This construction site shows how Dutch contractors can use Neargrid to build powerfully, quietly and future-proof even in the middle of the city and with limited grid capacity.
