i do wonder if when there is so much wind they must have to switch some turbines off , i mean you cant ramp down nuclear quickly and overseas input/output needs to be stable so maybe.

The United Kingdom is making waves in the offshore wind market and renewable energy goals. The country’s aim to increase the offshore wind energy capacity to 50 GW by 2030 and achieve net zero greenhouse gas emissions by 2050 is on the right track with the upcoming projects. Major projects like Hornsea 3, East Anglia Hub, Berwick Bank, West of Orkney, and Ossian can power millions of homes and contribute significantly to reducing carbon emissions. Collaboration with industry leaders and meticulous planning like strengthening the supply chain and creating job opportunities are key aspects of these upcoming offshore wind farm projects.

I'm told they only generate power between about 8mph and 45mph, they disengage and feather when the wind reaches the max speed. It does vary from make to make a bit.

I've heard similar but I wonder if that applies to more modern turbines. I've noticed a high corelation between strong winds and free electricity here on the breezy South Coast. Far higher than the correlation with sunny days.

nope they have very clever gearboxes that increase/decrease gearing as the blades spins up/down so they keep the speed within a certain range, like an alternator taking on load.
not sure about stopped turbines though, maybe just not needed, or awaiting checks or service.
not all turbines run all the time it does depend on the requirements of the grid, recently we have had huge
amounts of solar. also remember we cannot throttle back nuclear it runs at a certain load all the time.
i suspect recently we may have actually been way oversubscribed with renewables.

@swanseamale47 if you look back at my first post below you will see we were actually maxed out on renewables some days
23rd August 2024
Nuclear was at its standard base load
Fossil on tick over
import/exports pretty neutral
pumping water for hydro
at times like this some wind will be shut down.
our current flat out wind capacity is 28GW/H so as you can see below we were only using 14GW/H barely half as there was so much solar in use.

Interesting article here on the problems this causes.

Tl;Dr: we are often generating so much green power that the generators have to pay people to take it away. This reduces people's excitement about investing......
Meanwhile it's now about 18 months since I changed my octopus DD to £5 (the lowest they will allow). 18 months of gas, electricity and motoring later and I have a higher credit balance than when I started. Houses can be net self sufficient.

Awesome stats, but why are the bills still so high then, it was all due to Putin and Russian gas, so what gives if it's such a small percentage of the power supplied?

Because Tory government.......
Somebody else will have the exact version, but it's something like no matter what energy costs, you sell it as though it were generated by burning gas. So if you make cheap solar, then when gas goes up you have to sell it for more money - making enormous profits.
You could argue this has been a very effective way of incentivising investment in renewables (and look how well it has worked!) - you could also argue it's an extremely immoral way of keeping millions in fuel poverty.

Ah yes I remember reading that now. Yes, an investment in renewables, and to be fair, it is increasing rapidly and with labour removing the planning blocks about to accelerate again. But then other countries are achieving similar without huge rises in bills due to government price caps....

The main reasons above are accurate we keep the costs of renewable higher than it should be to encourage investment which is what is driving the country forward.
solar farms and wind farms are expensive to build just like gas powered generators and lets not talk about the most expensive power ever nuclear.
once we are over the "hump" of major investment we should start seeing reductions and also of course cleaner air.
One of the biggest problem that has set us behind was the Tory ban on wind farms from 2015 that had only been lifted, this seriously impacted the ability for growth.
They set rules where even a single person objecting could cause an entire farm to be refused, this has now been overturned.
