How to Plan Temporary Power and Cooling for Construction Sites

Power and cooling should be planned as changing site systems. Work fronts, cabins, occupied areas and equipment loads move through phases, so one early equipment list is rarely enough.

1. Divide the requirement by phase and zone

  • Map work fronts, temporary facilities, occupied areas and equipment locations for each programme phase.
  • Identify when each load or cooling zone starts, changes and ends.
  • Separate critical loads from deferrable loads and record any continuity requirement without assuming a fixed service level.

2. Build connected power and cooling briefs

  • The power brief should include running and starting loads, voltage, phase, frequency, distribution, cable routes and crossings.
  • The cooling brief should include use, occupied area, envelope, outdoor conditions, people, equipment heat, ventilation, humidity and air distribution.
  • Cooling equipment electrical demand must be included in the temporary-power load schedule when generators supply it.

3. Plan placement and routes

  • Review access for delivery, lifting, refuelling where applicable, maintenance and later removal.
  • Keep intake, exhaust, heat rejection and supply-air paths suitable for the selected equipment and site plan.
  • Define cable routes, distribution points and protected pedestrian or vehicle crossings before deployment.

4. Confirm interfaces and responsibilities

  • Record who provides connections, distribution, earthing, controls, water-side or air-side work and commissioning.
  • Use selected-equipment data for final electrical, piping, duct and structural interfaces.
  • Coordinate site safety, permits and responsible approvals through the project team.

5. Control changes during the rental

  • Update load and cooling schedules when new work areas or equipment are added.
  • Do not connect unreviewed loads or change routes without checking capacity, protection and operating conditions.
  • Keep an agreed path for reporting faults, planned shutdowns, access constraints and scope changes.
