Mobile Energy Storage Powers Electric Operations

in Norwegian Tunnel Construction

Electrifying tunnel construction involves more than putting electric machines to work.

It also requires a reliable power supply in an environment where space is limited, access can be difficult and several types of equipment must operate side by side.

In a Norwegian tunnel project, our mobile energy storage system is being used to support electric construction operations, providing DC fast charging for electric trucks and excavators, alongside 400 V three-phase AC power for tunnel machines.

Supporting Electric Equipment Underground

Air quality and noise are persistent challenges in tunnel construction.

Diesel-powered machinery adds exhaust emissions to an environment where ventilation is already critical, while engine noise contributes to demanding working conditions.

Apparatus electricus modum practicum praebet has actiones ad fontem minuendas. Cum nullis emissionibus exhalationis dum operatur et cum minore strepitu operationis, camiones et excavatores electrici possunt adhibere ad creandum ambientes laboris commodiores sub terra.

Tamen, machinas electricas in servitium ponere etiam mutat quomodo energia in loco suppeditanda est. Ad altam potestatem vehiculorum replectorum et ad postulationes electricas apparatus constructionis satis faciendum est in eodem ambiente laboris.

Unus Systema Mobile pro Diversis Postulationibus Potestatis

In loco operis, systema mobile storationis energiae praebet celerem repletionem directae currentis pro camionibus et excavatoribus electricis.

Eius output AC trifaseos 400 V ad machinam foraminis, ad applicationes ultra repletionem vehiculorum suffragans.

Haec functiones simul adducere permittit systemati ad diversas postulationes operationales servire sine tota dependentia ab installationibus separatis potestatis pro singulis applicationibus.

Its mobile design also offers flexibility as work progresses through the tunnel. With a plug-and-play setup, the unit can be deployed where power is required, helping reduce the complexity of establishing temporary electrical infrastructure in a confined construction environment.

Bringing Power Closer to the Work

For contractors, electrification is not only a matter of choosing electric machinery. Charging access, available power capacity and the practicalities of moving equipment around the site all influence how effectively electric machines can be integrated into daily operations.

Mobile energy storage addresses part of this challenge by acting as a local power hub. It combines substantial energy capacity with high-power output, supporting rapid vehicle charging and the operation of power-intensive equipment. Where grid capacity is restricted or permanent connections are impractical, it can provide an additional layer of flexibility within the site's overall energy setup.

Proiectul norvegian al tunelului ilustrează rolul pe care stocarea mobilă a energiei îl poate juca în această tranziție: conectarea mașinilor electrice cu infrastructura energetică necesară pentru punerea lor în funcțiune.
