The substations decribed in the power network case study above are for local distribution – 33kV stepping down to 11kV (×2) and 11kV to 415V (x12).
The substation on fire (North Hyde) is a 275kV major distribution substation.
That's a fairly significant distribution loss in itself (not just Heathrow but also 16,000 homes), and rebalancing the distribution will need careful coordination – flipping the switch on a load the size of Heathrow would then imbalance the network for the new distribution supply site.
- traceroute66 2y ago> not just Heathrow but also 16,000 homes You are off by a large number. More like 62,000 customers affected (although "only" 4,800 are actually without power right now)[1]. Also that area is more than just "homes". There is a lot of heavy elecrical load commercial stuff going on in that area too.
