11.36 Gw now, another new record.
Wind power is also the largest single contributor to the grid, and has been for some hours.
I suspect that this is the first time that wind power has been the largest source for a sustained period, on a weekday, during working hours.

Edit to add, reached 11.5Gw later the same day.

Wind has had a good week. Looks like it has been above 5GW for a lot of the week.

On another note the wind farm I worked on has already been officially opened.

Wind is currently the largest input to the UK grid, a situation routinely achieved at off peak hours, but still unusual during working hours.

11GW, which is impressive though not a record.

Not if a warming world increases air conditioning demand.

Now soon before a windy warm Sunday night sees UK demand fall and wind supply rise to the point where no gas or coal is required?

I suspect not before most of the the UK nuclear plants reach end of life.

EDIT

using 2018 gridwatch instantaneous (5 minute ) data,
minimum demand = 18,78 GW

max wind = 12.12 GW
max nuclear = 8.33 GW
max biofuel = 3.09 GW
max Hydro = 1.05 GW

so we already have theoretical potential to meet 125% of demand from
non-fossil sources at point of minimum demand.

This assumes the data is accurate and not noisy.

EDIT 2

A more realistic figure for minimum demand would be 20GW.

The result still holds.

Wind confirmed at a record 14.9GW , 32% of demand at weekday evening
peak.

I've just signed this: Petition to keep Kirkby Moor wind farm going for another few years:

Indicated power from wind is now 12.38GW which I suspect to be another new record.

As shown by Gridwatch, other sources may differ.

Wind has been at or about 10GW (metered) almost continuously for the last 96 hours. Over this period I suspect wind has come very close to beating NG into second place for power generation.

Forecast is to remain very windy for a few more days at least...

Metered wind at 11.3 GW, total estimated renewables supply over 20GW according to http://www.mygridgb.co.uk/dashboard/ - maybe a bit high.

This is over 50% of UK peak weekday demand. Current estimated carbon intensity 133 gCO2/KWh.

If current trends continue the UK might just meet its legal target of 100gCO2/KWh by 2030.
