Michael presented at the Berlin Geomob. His website has a more general overview of what he does: https://www.michaelcruickshank.me/recentwork. That does not seem to include a lot of detail on what he presented. Possibly because he is trying to be responsible here.
The security angle did come during the presentation. This is not the type of information that a lot of governments would want to make public but also something that could help them. You can mine a lot of intelligence from public data. And his approach of doing some kind of scenario modelling on top of the open data actually is interesting. That's something that can be used for good and for evil. And obviously something that a lot of intelligence agencies are probably already doing.
There are cables not on this map that are uncharted for things like acoustic monitoring & finger printing of vessels.
I was told that Texas maintained its own energy grid independent from the rest of the nation’s eastern and western grids, and supposedly only had a handful of high-voltage DC lines running between Texas’s and the rest of the nation’s. Supposedly this was why we couldn’t rely on excess capacity from anywhere else in the nation while our power generation capability was down.
But this map doesn’t seem to show Texas as isolated - there appear to be many lines in and out and no clear separation?

Those are ERCOT load zones, a distinct concept and all within the ERCOT interconnection (grid).
On the markets side, Texas is made up of ERCOT, and then has portions in (descending order) MISO, SPP, and the non-market West.
In terms of "grids" Texas is mostly ERCOT, and then the Eastern Interconnection with a small smidge of Western Interconnection in the far west in El Paso Electric's territory.
I had a fascination with how different the poles looked and how the equipment was mounted. It seemed like no two pylons were alike.
Based on this map, it looks like all of our power comes from hydroelectric.
I love this site. I just wish it was more complete. There are some major water and natural gas pipelines that aren't recorded. Maybe in time.
Unfortunately I don't have a source, and would appreciate a UK national with better understanding than me to chime in :)
Also even in a European context UK power prices aren’t as high as many of its peers.
Everything on the left thereof was then without power for multiple days as this was a single point of failure.

I also tried to see any vulnerable sabotage spots that would put my electricity out, but that seems harder.
I wonder how easy it would be to prepare a query in osm to find all such cases.
I know the areas from Alice west to the coast and north to the equator fairly well.
Rail lines are missing, it appears to be just "big" power lines and that's 'accurate' in the sense that South Australia doesn't share power across the Nuallabor to Western Australia and many northern towns are 'independant' of any state or territory grid, running on a local generation basis.
Doesn't show Pine Gap or the Naval Communication Station Harold E. Holt base either . . . :-)

ad: if you have Android I can recommend StreetComplete (great for newbies)
if you have iPhone - GoMap!! is great though a bit more complicated to use

The ACT government provides ~10cm aerial imagery of Canberra and surrounds a few times a year and from this imagery, unless a minor power pole is obscured by trees or a building, it is generally easy to identify most poles. Evoenergy (distribution operator for the ACT) also publicly provide detailed maps of poles and lines no matter how minor they are. The reason this detail won't be mapped in OSM is lack of interest and availability of mappers to micro-map every minor power pole from aerial imagery, and OSM's very conservative approach to importing datasets, particularly from a licensing perspective (e.g. attempting to apply European database directive concerns in countries like Australia which don't have equivalent laws, and even have opposing case law precedents).
Australia is one of the most open countries when it comes to supplying electrical grid data. Even underground conduit locations are available publicly for most distributors, as well as designed summer/winter constraints for each transmission line (e.g. maximum kA per line). See [1] for some links to maps and other data that is made publicly available.

Wanted to do a map of the power network here in Romania, hadn't thought to check if anything similar already existed, or I couldn't find it myself, at least, but it seems like this map has (almost) all that I wanted to do in that respect, including the position of the power poles on the ground.
6000km sounds like a lot, but the Chinese have built a 3000km UHVDC line delivering 12 GW, and putting down submarine communications cables this long is complete routine today. Would be interesting how much aluminium/lead/copper such a project would take. EDIT: found a supplier that specifies a 1GW cable at 7000 tons per spool. A spool is 130km of cable, so that's 350 000 tons of cable per GW for the transatlantic link. So just the raw aluminium is around a billion dollars per GW.
Anyway, first we have to properly connect those two sun belts to the rest of their own continental masses with UHVDC, then we have a lot of political problems to solve, and then we can check battery prices...

The public source of this data (ArcGIS Feature Server account of Transpower) shows data last modified by Transpower in October 2025 for pylons and February 2025 for substations. At the rate of development of NZ, you wouldn't expect major changes to any of this data unless it's a major transmission upgrade project identified years in advance in hundreds of public announcements and documents.
For distribution, the largest distributor in NZ (Vector) provides "Line" geometry at https://www.arcgis.com/apps/mapviewer/index.html?url=https:/... (note: not included in AllThePlaces due to ATP not currently collecting geometry other than points)
From what I can see it's pretty complete and up to date for my area.
That said, https://nl.wikipedia.org/wiki/Centrale_Hemweg says the plant was converted to natural gas, not decommissioned, in 2019, and this is correctly reflected in Open Street Map / Open Infra Map. Do you have a citation that contradicts this?
So it is missing in OpenStreetMap-based map.

while such open data has also positive effects
have you considered both? it is not like deleting power plant from single map would hide it

Apparently the data on where the exchange was and how it would affect the surrounding neighbourhoods was openly available. The neighbourhoods affect were largely affluent.
It’s probably also the reason why this is being reshared.
One can see easily make out the power station Lichterfelde and the affected substation inside of it. The area to the east of the power station was without power between Saturday and Thursday morning.
I heard multiple times that professionals in the energy sector relied on shitty, difficult to obtain and incomplete information until the open source revolution.
Soviet Union heavily edited publicly available maps, although it had great cartography for the military-industrial complex. And where it is now?
