Wind at 14.5GW at the moment according to Grid Energy Numbers - must be a bit breezy out there in the sea

Yup, lots of greenish-yellow around the UK on Ventusky right now https://www.ventusky.com/?p=53.6;1.4;4&l=wind-10m which means windspeeds around 12-15 m/s , which is within the sweet range (12-25 m/s) for max power output.

More, including generation at individual farms, at https://www.thecrownestate.co.uk/en-gb/our-places/asset-map/#tab-2 - currently 17.8% of UK power coming from offshore wind.

Today is a good renewables day; wind + solar = over 53% of total grid demand:

This week looks good for records, I don't think I have ever seen such a consistent windy forecast for the whole UK and it lasts for the whole week.  snow

Spot on. We've just broken the record for highest average wind generation over a rolling 1-week period (336 consecutive half-hours) - 11.1 GW and still rising. Highest previous was 10.5 GW. This gets added to the four other records that 2019 had already broken:

1. highest share of wind generation on the grid, 49.8%, 13 Jan

2. highest share of interconnectors on the grid 15.8%, 24 Feb

3. highest absolute wind generation, 15.3 GW, 8 Feb

4. highest share of asynchronous generation (wind+solar+interconnectors) on the grid, 63.6%, 9 March

this may mean that wind has been the largest producer for a whole working week ?  Thats got to be notable. Dont know where to look to check this out.

Yes, it does.

This is only the second block of time that that's happened. there was a very windy stretch from 14-24 Sep last year when wind was the single largest producer for a whole week (336 consecutive half hours), so we can pick any week-long period in that block and wind was the largest producer.

The current very windy block started on 5 March at 18:00, so we can pick any week-long period since 12 March 18:00 and wind was the largest producer for that full week.

For the week ending midnight just gone, on average wind generated 11.2 GW, CCGTs generated 10.4 GW, nuclear 5.5 GW, PV 1.2 GW, coal 0.7 GW, (edit: and 0.7 GW interconnectors, plus a bit from run-of-river hydro and other)

Wind has certainly been good this last week and may be even better if it lasts another couple of days at close to 10GW (per Gridwatch). 

I am more interested in low carbon generation which includes nuclear (they are there, so actual current generation is low carbon)

I seem to under-estimate solar - I add up the daily peaks, divide by two and guess the generation time frame (about ten hours per day at present?).  This last week only came out to about 0.9GW by my rough estimate.

I include hydro (not pumped, mind, which is sub-fossil fuel effectively), but donít like to include biomass (because of the wood burning generation).

Are those figures the average power output? How many GWh for each source over the week?
