> New wind power records are set regularly, and between 5:30pm and 6:00pm on 5th December 2025 British wind farms averaged a record 23.94GW of generation.
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 :/?
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 harder thing to get working.
What are the black dots around the map when you zoom in? For instance South-East Wales / Bristol, I see a few black dots that look like they cover shaded areas or something. They also show up at the sites for wind farms, possibly they're the turbines themselves?
Nice job dodging the awkwardness of whether to include Ireland, Northern Ireland, etc (IE and NI operate as a single, all-island wholesale electricity market). :)
Are those gas plants not peakers? It seems wild to me there is 5gw of curtailment while there is 16gw of gas going. Surely the grid could use some more storage capacity.
It might be that the grid lacks the capacity to transmit the power from renewables. i think I read somewhere recently that there is an argument going on about adding or upgrading connections in East Anglia.

Cool!

Let me know if you have any questions or feedback and I'll do my best to respond to them.
Would show that off and zoom into them when selecting them from the list view!
Been following your projects and writing since the Mozilla days, always impressed!
