Prepare to lose a lot of time just idly zooming around a map that shows major power cables and facilities not just in the UK, but worldwide.

It’s one of those online things that looks like it might be exceptionally useful somehow, even if you can’t think how it would be of use — and yet is wonderful to know it exists.

And to see just how much sits under the streets of London delivering power to homes and offices, and the data centers delivering lolcats to smartphones.

I suspect from looking at a few of them that they’ve been added by people making some reasonable assumptions about the locations of the tunnels, as they are mostly very straight which is unlikely in the real world, and a few look a bit off from personal memory.

But that’s to quibble over something that’s really quite time consuming in how long you can spend just zooming around to see what’s there, what’s that thing, how big is that tunnel.

The Open Infrastructure Map is here.

This website has been running now for over a decade, and while advertising revenue contributes to funding the website, it doesn't cover the costs. That is why I have set up a facility with DonorBox where you can contribute to the costs of the website and time invested in writing and research for the news articles.

It's very similar to the way The Guardian and many smaller websites are now seeking to generate an income in the face of rising costs and declining advertising.

Whether it's a one-off donation or a regular giver, every additional support goes a long way to covering the running costs of this website, and keeping you regularly topped up doses of Londony news and facts.

If you like what you read on here, then please support the website here.

Thank you

    Enjoy indeed. So that’s what that building is moments aplenty. Thanks.

    Not sure how accurate the Open Infrastructure Map is…

    There is a 5MW hydroelectric plant (built 1997) about four miles from us and it isn’t on the map nor is the 33kV line which links it into the National Grid.

    And is it really a good idea to publish this stuff? A couple of days after Abu Bakr al-Baghdadi was killed isn’t it waving a red rag before a bull? [Yes, I know bulls are colour blind to red…]

      Complaints that it’s not accurate – and complaints that it’s so useful to terrorists that it shouldn’t be published.

    The Nazis seemed to have very good maps of our vitals, and so did the Soviets. Presumably nothing much is really secret.

  4. Richard King says:

    I used to live just off the Wandsworth Road and 30 years ago got a letter saying a major tunnel for power cables was coming under my house. Asked if I had any wells on my property, ignored it.

  5. Richard King says:

    Having just checked the map it doesnt show any tunnel anywhere within half a mile of my former home. I also remember a very small drilling rig in the street drilled a vertical test hole and was then covered by a small metal manhole. Was still there when I moved 15 years ago.
