Rapid Sustainable Power

A fully-equipped electrical substation, the mobile substation or portable substation is designed to be a multi-purpose package delivering maximum MVA for allowable weight and size. Depending on selected features and configuration, the mobile substation can be mounted on one or more semi-trailers. Performance and design criteria vary considerably from those of a conventional substation.

  • Circuitry is more complicated to meet a variety of operating situations.
  • Mobile substations operate at a higher power density than stationary units, therefore losses are higher. Utilities use a mobile substation only until a suitable stationary unit is obtained.
  • Range is from 5MVA up to 60MVA, with voltages no higher than 245KV.
  • A typical mobile substation includes the semi-trailer/s, switchgear, breakers, emergency or station power supply, protection and control, a compact high-power-density transformer and enhanced cooling capability. 
  • Within existing substations (emergency backup power systems)
  • Refurbishment, maintenance or repair of existing substations
  • Equipment failure for substations without spare capacity
  • Power supply during main equipment failure or natural disasters (fire, flood, transmission line freeze) when quick replacement is not available
  • Standby supply for peak loads in areas where power demand expands further than the planned increase in main system capacity (backup electrical power systems)
  • Power supply while a permanent substation is under construction, which could take two to three years (temporary service)
  • Primary power supply in isolated areas (new service)
  • Rapid deployment and completion within six to eight months
  • A “plug-and-play” solution that is quickly assembled onsite and ready to perform within a few hours
  • A compact design that does not require special civil works
  • Up to a 60% smaller footprint than a conventional substation
  • Compliance with ANSI or IEC standards
