Biggin Hill lost all power?

[SpoolingUp]

Apparently Biggin Hill lost all power this morning - I thought airport towers were meant to have multiple back ups? UK CAA will surely investigate?

They have standby generators that cut in within 15 seconds of a mains power failure. System tested on a routine basis. Something else must have happened.

Of course it could be argued that once on backup power you no longer have a further backup! So you use the backup power purely to achieve an orderly shut down of operations

If a country's Area Control Center can have a complete power outage (https://mobilit.belgium.be/sites/default/files/downloads/accidents/2015-05_final_report.pdf) then certainly a regional TWR can suffer the same problem.
But nevertheless, something else could have happened here...

Something else must have happened.
Did they replace the diesel with solar panels?

Blackbushe gained it's first ever visit of a G4 due to a diversion because of this power failure
