sorry, missed an important technical part:

The power cut was due to an overvoltage, which also damaged emergency generator switches. "Normally, the generators should take over, but because the excess current broke the control switches, this was rendered impossible. It was like Murphy's law", said Mr Dehaene.

The defect caused all control towers to fall short of electricity. The cause of the overvoltage itself, however, is yet to be found.
