@jwheare Thanks! The % is a simple boundary flow (without subtracting curtailment) vs. boundary limit taken from the day-ahead forecasts by NESO

I'm currently working on a better way of calculating this with other datasets.

@russss Happy to get suggestions on how to improve it though. It was melting my brain a bit so I decided to just go live as-is, if a bit confusing.

@russss I've wondered this too (about storage). I mean technically it's a reduction in output vs. reported PN, plus it often goes even further into the import.

In my head it still makes sense to count that as curtailment (or at least turn-down) as it's still an accepted bid to reduce output (or soak up demand) and reduce pressure on a constraint.

Certainly needs some thought and tweaking though.

@scvalex I've wondered the same thing, I think all the colours can be changed if I'm honest.

Perhaps biomass can be a poo brown to match the colour of the fuel pellets.

@russss Indeed! I have some ideas but at some point I'm concerned I'm massively overloading the map so I need to take a step back and think about how to approach import vs. export. It also makes the curtailment and turn-up actions hard to make sense of visually.

@russss Thanks! Yeah good point, I need to completely strip that out and rewrite it as it's incredibly dated by now.

I'd also like to thank you for all the support and encouragement as I build this free resource in my free time (yup, this isn't my job).

Honestly, it's been an incredible motivator and the discussions over the years have taught me a huge amount that has only made the map better for everyone.

Until the next update!

And I'm only getting started!

This update was the original goal of creating the map a few years ago. Now it's here I can shift focus to all the other ideas I have for it…

Oh, and there's a new feedback button at the top. Please use it to let me know of any issues you find (there will be plenty) or suggestions to help improve this resource for everyone else.

There are numerous other updates as well:

Click the plug button to see a curtailment view, now including turn-up and a better visual representation of turn-down and turn-up actions

️ Tooltips include loads more detail about fuel type and balancing actions

️ Each fuel type can be toggled using the map buttons

🧠 Map state is remembered when you reload or revisit the website

Lots of new and under construction power assets are now on the map

It's here! All power assets are now live on my GB Renewables Map

That's right, it's not just wind farms any more. Now you can see live and historic data for gas power plants, nuclear, grid batteries, biomass, pumped hydro and even a bit of solar.

Wind farms are still the default for now, though you can enable as many or as few of the other fuel types and your selection will be remembered when you come back to the website.

It's already live so go play for yourself:
