From (the real) Gridwatch, it appears that Gas outperformed Wind for a 15-day period, from the 8th to the 22nd inclusive.
Judging by eye, the difference was an average of 11GW, for a total of 4TWh.
In December there were four short periods where Gas had to step in again,
for an estimated 2TWh.
And in November there was another series of days, totalling 18, where Gas
was the main provider, for some 4TWh of Wind shortfall.
Since there was insufficient surplus energy available to recharge any
battery farms that could have supplied these shortfalls, it would seem that battery storage is a non-starter as backup to Wind.

There is next to no "green" hydrogen in the uk and more generally it
cannot be distributed via the existing gas grid pipeline as hydrogen is
too small and would leak through those pipes.

Was there surplus interconnector lecky available from abroad but the
price was wrong compared to gas generation?

Just came from a presnetation about this:

They're at the stage of installing solar; next stage is converting surplus electricity to hydrogen.
I (clearly) can't follow the science - they and the assembled seemed very enthusiastic.

Seeing the term dunkelflaute, I realised I'd forgotten what the opposite
term is.

I took the gamble of going for the Octopus tracker tariff (October
version and my region seems to be more expensive than most). For the
whole of November I paid around the same as the capped rate for both gas
and electriity. December and January I paid significantly more than
their fixed rate, at rate lower than the capped rate. There were only a
few days when the price fell below the fixed rate by more than 10p/unit
for electricity. I can confirm that the prices were high(er) during the multiple Dunkelflaute events when demand was also high.

We're a couple of weeks away from a full year on Tracker - the December 2023 tariff which is a bit cheaper than the current one. With heating being ASHP most of our electricity demand comes in the winter (heating runs 24/7). Here's the numbers (first two weeks of Feb 24 on the flexible tariff):
£ kWh St.chrg£ p/kWh exc st.ch.
Feb24 177.71 724.25 12.18 22.85
Mar 150.92 742.04 13.02 18.58
Apr 115.49 572.23 12.60 17.98
May 101.17 442.29 13.02 19.93
Jun 92.17 402.00 12.60 19.79
Jul 90.18 392.44 13.02 19.66
Aug 90.48 417.92 13.02 18.53
Sep 94.55 398.37 12.60 20.57
Oct 121.71 505.00 13.02 21.52
Nov 197.71 794.41 12.60 23.30
Dec 210.32 889.06 13.02 22.19
Jan25 322.33 1193.06 13.02 25.93
Total 1764.74 7473.07 153.76
Average cost per kWh exc. standing charge 21.56p
Average cost per kWh inc. standing charge 23.6p
So even after a heavy winter it's still beaten the flexible rate, although not by so much - and the current tracker tariff is worse.
I'm waiting until it expires and will then ponder where to go next.
Some of Tomato's tariffs look interesting.
