Fire broke out over 24 hours ago in a cable tunnel in Kingsway, London, and is still burning.

Several thousand customers lacked power, people evacuated. Still ongoing with a gas main now damaged and the escaping gas burning at pavement level.

More details from the news site of your choice.

This is hardly TEOTWAWKI, but is does show the importance of both individuals and companies being prepared for this sort of thing.
I expect restoration of grid supplied electricity to take some weeks in the worst affected area, though supply should be restored to most within 24 hours by large generators instead of the grid supply.

Anecdotal reports suggest that very few standby generators worked, and that fewer still ran for more than a few hours.

SEE SIGLINE BELOW Laughing

Probably an old and/or overloaded cable that just gave up. For an interesting insight on what can happen to a city research the Auckland (New Zealand) power outage of 1998.

I am sure there are a lot more of these cables just waiting for their moment to fail.

Agree, though the load at the time of failure was not exceptional. In London the greatest risk of electrical infrastructure failure is during hot weather as the load is then greatest due to the air conditioning demand.

BTW, my sigline is a quote from the inquiry into the great Auckland power outage of 1998 Smile
