Ask HN: Blog post about high-voltage electricity transmission / sub-station?

[sloucher]

I'm looking for a blog post I saw on HN some years ago (maybe 3) about an underground electricity sub-station. It may be been couched as "what's that mysterious building" or somesuch, but it delved into high-voltage cables and how they need to be cooled with (flammable!) cooling oil. It was fascinating, and I'm keen to re-read it, but Google fails me. Hoping the poster is still around... and sees this before this question (rightly) gets taken down :-)

Could it be this?

Sadly not - it was a longer post than that, but that's an interesting one nonetheless - thanks!

BUT, it's linked from the page you linked (https://www.jwz.org/blog/2002/11/engineering-pornography/) - success! Thanks so much.
