Here’s Gridwatch – real time monitoring of where the UK is getting its electricity:

https://gridwatch.templar.co.uk/

Maximum capacities:

30 GW CCGT = Combined Cycle Gas Turbine – modern and efficient.
6.5 GW Nuclear.
15 GW Wind.

2.7 GW Pumped storage.
1.2 GW Hydro.
10 GW Solar.
2.9 GW Biomass.
4.0 GW Coal.
0.8 GW OCGT = Open Cycle Gas Turbine – old and less efficient.

ICT – bidirectional interconnectors:

+/- 3 GW – France.
+/- 1 GW – Netherlands.
+/- 1 GW – Ireland.
+/- 1 GW – “East-West ICT”.
+/- 1 GW – “Nemo ICT”.

Sometimes, wind-generated electricity is very plentiful. There is considerably more capacity than the 15 GW shown because private wind turbines are not metered, showing up instead as a reduction in demand.

The wind is always blowing somewhere but there are only 7 GW of international transfer ICTs.
