Main characteristics to consider for the implementation of an MV back-up generator:

  • Site activity
  • Total power of the installed loads
  • Sensitivity of circuits to power interruptions
  • Availability of the public distribution network

The preferred basic configuration does not include an MV generator. Certain factors contribute to installing an MV generator:

  • Site activity: process with co-generation, optimizing the energy bill,
  • Low availability of the public distribution network.

Installation of a back-up generator can also be carried out at LV level.
