Let me begin by setting out what we currently know about the cause of the incident. A large fire broke out at North Hyde substation at 11.30 pm on Thursday 20 March, and was brought under control the following day. Due to the impacts, Heathrow Airport announced at 4.30 am on Friday that it would close until midnight that day. Power was restored to domestic customers in a matter of hours, after the operator of the local distribution network, Scottish and Southern Electricity Networks, redistributed power through other parts of the network.
