UK power cut: Disruption was 'incredibly rare event' - BBC News
The National Grid's operations director explains why nearly one million people lost power on Friday.
The power outage across England and Wales that left nearly one million people without electricity was an "incredibly rare event", in the words of the National Grid.

Operations director Duncan Burt said that it was caused by the "near simultaneous" loss of two large power stations, with power cuts caused by measures to protect the electricity supply.
