DEWA energisation: the approval chain behind your switch-on date

Energisation is not one application. It is a chain of dependent approvals, each waiting on a predecessor you may not control. Here is the order things actually have to happen in, and the four places a Dubai project usually loses a fortnight.

  • Every DEWA milestone has a predecessor outside the contractor's control — programme backwards from the switch-on date, not forwards from mobilisation.
  • Load fixed at concept stage and never revisited is the most common reason a substation has to be re-sized late.
  • Site-readiness items — access route, room finishes, earthing, ventilation — fail more inspections than the electrical installation does.
