Temporary & off-grid power

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.

Context

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.

EOS method

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

  1. Assessment

    Scoping of needs, load profile and site constraints (access, noise, autonomy).

  2. Engineering

    Source sizing, generator selection, distribution diagram and selectivity.

  3. Design

    Layout drawings, temporary cable routing, earthing and protection.

  4. Deployment

    Installation, functional testing and commissioning on site.

  5. Operation

    Supervision, refuelling and adjustments over the duration of the operation.

  6. 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.
