Love this! Would be super interested in any details the author could share on the data engineering needed to make this work. The vis is super impressive but I suspect the data is the hardee thing to get working.
This has just had a major update to include other renewables (eg hydro, solar) as well as non-renewable energy sources (gas).
It’s also added grid boundaries and cabling recently - and I think there’s also wind roses planned?
My one UI wish - the energy sources filters are currently displayed as options on the map - rather than controls for the entire UI - which meant I missed them entirely at first. Would be great if they could be given more prominence.
Hey Robin, big fan of this map, congrats on getting front page on HN :).
Two suggestions/questions if you may:
1) Would be good to see how many MW each boundary can handle, not just %? Btw, I can't see the number for the south east england boundary.
2) Great job on the battery info. I'm seeing some battery storage is curtailed. How is that possible? Please don't tell me that we are paying batteries to _not_ export :/?

Oh wow, I made this! I didn't expect to see my map on here
Let me know if you have any questions or feedback and I'll do my best to respond to them.
Can someone explain what the lines mean?

It's pretty windy here today! Around half of the UK's generation is currently coming from wind[1]

Cool!
Great visualisation...but doesn't seem to have any display of the amount of Solar (though won't be much on such a cloudy day!)
Great work, this is so cool to see!
