better keep fingers crossed that gas imports continue uninterrupted then, otherwise it's lights out.

From link
| Quote: | | The Hornsea decision was due to be announced two months ago but was delayed amid fears the noise of building the massive windfarm would disturb porpoises. The Department for Environment, Food and Rural Affairs proposed designating a vast, 36,000 sq km (14,000 sq mile) tranche of the North Sea – including the entire 300 sq km area of the proposed wind farm – as a special area of conservation for the harbour porpoise. A habitats regulations assessment was carried out to look at “the likely significant effects of the project, both alone and in combination with other plans and projects” on the porpoise protection zone. |
Politicians don't give a stuff for nature.

Not today though. It is, as I write, Coal = 7.33GW Wind 1.16GW. We have a 45GW demand and 23GW is produced by CCGT. I don't know how the gridwatch dials are representative of the limits for each category, but they are all near the limit except for wind, but when he wind don't blow you won't get much.

Indicated wind power currently at virtually 7GW which I think may be a record.
With the present perilously low natural gas stocks, this is most welcome as every GWH generated from wind is about 2.5GWH* of natural gas not burnt and therefore still in stock for later.
*no great accuracy is claimed in this figure, the efficiency of natural gas into electricity varies a lot according to age and design of the plant, load, and for how long it runs.
Edit to add, now over 7GW from wind.

According to this, it is currently 10.1 GW and was 10.2 earlier, which is the highest I have ever seen it by a margin of about 2GW,

Yes, but the two figures are not directly comparable.
The approx. 7GW to which I refer is from the gridwatch website and only includes large scale wind power that is metered in real time.
The higher figure of about 10GW is the total of the metered wind farms, and an estimated addition for the total output of the many smaller wind turbines that are not metered in real time and the output of which only shows as a reduction in demand.
Still impressive though, whichever figure is taken.

Indicated power from wind briefly reached 7.16GW and at present is about 7.1GW which I believe is a new record.
The true figure is somewhat higher due to the contribution from smaller turbines that are not metered in real time.
This represents a lot of gas not burnt and therefore remaining in our limited storage for future needs.

An indicated 7.83 GW from wind at present, another new all time record and a significant advance on yesterdays short lived record.

I wonder if they are able use the turbines during stronger winds than a few years ago? Maybe grid upgrades, or stronger generator footings etc.
I still see some generators that never rotate. Can someone remind me of the scam behind this? I heard an explation a few years ago but I have forgotten. Some sort of greenwash transfer pricing tax fiddle thing? |

I am not aware of any means to gain financially by letting a wind turbine routinely stand idle when it could be generating power.
I would suggest that any turbines routinely idle at times of reasonable wind are defective, or if reasonably new are not yet commissioned.
In the short term, some new turbines might be idle if the grid connection can not handle the output power. It is however usual to do any grid upgrades in plenty of time.

Indicated power from wind is now exceeding that from nuclear power, and I think that this may be a first in the UK, at least during times of more or less normal nuclear output.
Wind 7.55GW
Nuclear 7.16GW.
Wind has recently exceeded 7.55GW but that was at a time when nuclear was over 8GW, so I think that today may be a first for indicated power from wind exceeding nuclear.
Actual wind power will be somewhat in excess of the indicated figure due to the many smaller wind turbines that are not metered in real time, these simply show up as a reduction in indicated demand.
