Unbelievably I can't see a discussion thread on this already.
Anyone actually believing that a single transformer/substation fire shuts fully down one of the largest airports in the world?

Final report published today https://www.neso.energy/document/363891/download
The cost to the Heathrow reputation is 10 times more than the stated financial cost of £20m. It is also worth looking at who were the decision makers and who has just sold off a large share of Heathrow airport from their portfolio.
Have a look in this thread for one of my previous post with attachment where I simply put
Worth a read
Not sure what happened at Heathrow but for sure the emergency lights worked and presumably the control tower standby generator but security devises in passport control and computers were probably run off the airports mains power circuits which were not backed up with emergency generation.
Same with the baggage handling equipment. Hopefully, Heathrow have by now installed these critical areas with standby plant as it certainly should not cost as much as £20 million.
Hello Sergio:
Just adding to my earlier comment- Based on the live view, the air around Heathrow Airport appears to be highly contaminated.

Hello Sergio:
Just for the record I watch (live feed) the planes arriving and departing every morning from Heathrow Airport using youtube.
With the 5 hour spread between Florida and the UK it is usually about Noon UK time.

back up generation
I did see one report (www.youtube.com/watch that suggested there was a potential fire suppression system on-site (just outside the electric fence;-), which may be the source of the 'generation' misunderstanding if it had some form of diesel backup for the fire fighting/suppression aspects. These things can be less reliable than typically hoped, but then again it might not even have been a fire suppression building that was being noted!
No grid substations or DNO substations have back up generation -for an Energy Minister to suggest there was shows the level of engineering knowledge he has.
No one is guaranteed a 100% reliable supply from NG/DNO -if electricity is that important to your site it is then your responsibility to provide back up generation to cover the grid power outage.
I guess at Heathrow the cost of back up generation would be huge, a 40ft container can house 2MVA of standby diesel generation and are commonly installed on hospital sites.in multiple configurations.- Heathrow could have followed this model.
It is reported the adjacent data centre continued operations - presumably with UPS supplies to cover the short time period while the standby generation ran up and connected.
From comments in the press it appears Heathrow had sufficient standby capacity to undertake an orderly site shutdown but not sufficient capacity to continue operations.
I wasn't suggesting that everything needed to be done in one night. There is such a thing as staging over weeks or months.
What happens when the airport has to close because of bad weather (example Fog).
My wife experienced a situation many years ago when her fight into London was delayed because of bad weather and her plane was diverted into a airport in Scotland for a few hours.
Just think what happens when the local clocks are changed in spring and fall and the airlines are forced to adjust their schedules.
