MV back-up generator

From Electrical Installation Guide

MV back-up generators are required when in case of the utility failure it is necessary to ensure the supply of the totality of the loads or the major part of them.

For all the other situations LV back generators may be enough

The main criteria to consider for the implementation of MV back-up generators are the following:

  • Site activity
  • Sensitivity of the loads to power interruptions
  • Level of availability of the public distribution network
  • Process including a co-generation system
  • Need to optimize the energy bill.
