Grid power is hard. Even with local generation failovers for air and ground safety systems, Heathrow is massive and uses a lot of power (1-2MWh/day). It's hard to route around that sort of demand.
I don't disagree that this is something that shouldn't happen, but that's what we say for almost every preventable grid failure. I think this is a national inconvenience rather than a security issue though. There are short-term alternatives which will be used.
