In Ireland, we’re running at about 75% renewables for the day, with most of that being wind. The absolute numbers are smaller, but that’s a peak of about 500 MW of solar and 3.6GW of wind, against something like 5-6Gw of demand.

I shed a little more light on the context via my map which you can also find linked on the page: https://renewables-map.robinhawkes.com

Not to steal from Robin's excellent work, you can see how much it's been (low carbon/renewables generation) over the last twelve months at https://app.electricitymaps.com/map/zone/GB/12mo/monthly (~56% renewables, ~73% low carbon)

(Robin, if there is a way to see this on your site, I could not find it, my apologies!)

Thanks! Always a surprise and a pleasure seeing my stuff on here

Great website! Can you describe the potential output? There is a little i sign but I can't click it on Firefox mobile.

(edit: I see you answered a sibling comment with the same question. TL;DR: Potential output is the output pretending that curtailment did not apply. Thanks!)

A UI or terminology question: when 'Potential output' says it is 'Including curtailment', does this mean that it pretends that curtailment doesn't apply, or that it subtracts the curtailed power from the total available so that the total power shown is only the power actually transmitted (exported) to the grid? It's very likely that I'm just not familiar enough with the terms, but this wasn't immediately clear. My guess is the former meaning, although I can imagine it meaning either.

Regardless, this is incredibly neat, and I'd love to see this kind of data for the grid that serves me (Eastern Interconnect in the US) -- are you aware of any sites similar?

Excellent Site!

What are the lines that cross Scotland ? At time of writing they are red where as other lines further south are green.

I know of some on shore wind up near the Rochdale area too. Does it mean they are offline if they just appear as black dots on the map?

Meanwhile the average EE prices for business in USD/kWh:

UK: 0.442 USA: 0.148 India: 0.124 China: 0.097 Russia: 0.096

Thanks! The ultimate fix is to finish upgrading the aging grid. There are other things that can improve the situation however, such as building wind farms away from these constraints, storage (but these can sometimes exacerbate constraints), demand flexibility (eg. place demand above constraints), zonal/regional pricing, and probably more I can't remember off the top of my head.

The demand flexibility aspect is already being explored: https://www.gov.uk/government/news/government-to-make-plug-i...
