Temporary and off-grid electrical power for construction sites and remote locations
Right-sized generators, mobile distribution and secured outdoor cabinets: EOS Électricité deploys temporary power and off-grid electrical solutions engineered for construction sites, events, remote locations and infrastructure under works.
A reliable energy source where the grid is absent or insufficient
Temporary power addresses situations where a grid connection is not yet available, no longer available, or intentionally bypassed: construction phases, one-off events, remote locations, maintenance operations on an existing installation. Off-grid power goes one step further and acts as the primary source of a site without any connection, with its own autonomy, cooling and safety constraints. EOS Électricité sizes, deploys and operates these sources — generators, AC cabinets, mobile transformers, low-voltage distribution — in line with the site's operational and safety constraints.
Challenges of temporary power
Sizing
Time-varying loads, inrush currents and the coexistence of sensitive equipment with heavy loads.
Autonomy
Optimising fuel consumption while guaranteeing the expected availability for the full duration of the operation.
Site safety
Cabinets, protections, earthing and labelling must remain compliant despite the temporary nature of the setup.
Environment
Noise, emissions and footprint — real constraints in urban, sensitive or occupied sites.
A temporary source engineered as a full installation
We treat temporary power with the same rigour as a permanent installation: load balance, distribution diagram, selectivity, differential protection, earthing, labelling. The choice of generator — rating, regime, possible coupling — is justified by your real usage, not by a generic rule of thumb.
Technical expertise engaged
Backup generators
Selection, sizing and integration of fixed or mobile generators matched to the load profile.
Mobile distribution
AC cabinets, flexible cabling and industrial connectors engineered for construction or event use.
Earthing
Sized and verified temporary earthing electrodes, with differential protection matched to the earthing arrangement.
Islanding and coupling
Operation isolated from the grid or temporary coupling with controlled transfers.
Operational follow-up
Supervision, refuelling and maintenance of the source throughout the operation.
Typical applications
- Construction and renovation sites
- Professional and cultural events
- Remote locations without a grid connection
- Maintenance operations on existing installations
- Temporary switchovers during grid works
Project methodology
Assessment
Scoping of needs, load profile and site constraints (access, noise, autonomy).
Engineering
Source sizing, generator selection, distribution diagram and selectivity.
Design
Layout drawings, temporary cable routing, earthing and protection.
Deployment
Installation, functional testing and commissioning on site.
Operation
Supervision, refuelling and adjustments over the duration of the operation.
De-installation
Removal of equipment, site restoration and documented after-action report.
Benefits of well-managed temporary power
Continuity
A reliable energy source aligned with the real duration of the operation.
Safety
Compliant protection and earthing despite the temporary nature of the setup.
Right-sized autonomy
Fuel volume and refuelling logistics calibrated to the real load profile.
Responsiveness
Rapid deployment in response to schedule pressure or an unplanned outage.
Traceability
Technical dossier and operating log handed over at the end of the operation.
Single point of contact
Engineering, delivery and follow-up owned by the same team, from scoping to de-installation.
