Whilst good to see coals continuing decline, this winter has shown several times that the question of what replaces that capacity is essential. We have maxed out gas and coal generation on multiple days when wind, solar and nuclear have all been missing in action...

Seriously bad news. As Dan B has stated, the coal plants provide good reliable backup when the others are not there. Trouble is, the carbon floor and low utilisation make the numbers poor.

I worked there as a contractor, sad to see it go.

This uk government of ours has taken its eye off the ball and allowing dessecration to the infrastructure not seen since WW2!

What also now does not help is Nemo link. Indirectly or very directly importing subsidised German  dirty lignite powerred electricity. UK loses taxpaying power workers money and we import electricity to the detriment of our countries wealth. It really stinks. The power is not green from Belgium as their nuclear is part shutdown. So the power is by default German coal instead. UK should bot import Dutch or Belgian electricity until Germany greens up it electricity production. Rant over.

Good Evening All,

Much as I support a transition to RE I also understand we need well planned flexibility for sometime in the future. As somebody who is purposefully changing their energy demand to more electric, as others are being encouraged to do, then I'd like to see a coherent plan in place. I'm not sure this is coherent.

Regards

I thought the very low prices of the last capacity auction were taken to indicate that the UK just doesn't have a capacity problem? I. E. I think we can meet demand without coal (presumably using gas). It's just that it would be more expensive. May be completely wrong here.

Gareth,
 
Overall, yes.  At all times, no.  Clearly obvious, because coal and gas have been running (almost) flat out, at times, recently.  2GW is 48GWh on a foggy still day that would need to be replaced somehow, every day it occurs plus the means to replenish any stored energy used up (while wind and PV were minimal).

As Philip R pointed out, importing fossil fuel generated electricity is neither helping the planet nor improving the UK balance of payments.  Ten Swansea-like tidal systems would be a good substitute, but the government is blind, or not wishing to invest any money (not their money, anyway) for fear of losing some votes.  The cost will be much higher further down the line!

It closed yesterday.
I had to trawl into the BBC Nottinghamshire news. Did not make the headlines. More interested in the PMs former activities.

You have to take into account that this plant had an original 30-year life, but has now been operating for 50 years and while it has received a lot of upgrades there is only so much to can do to 'improve' such a site.

Also, the main reason why it is being shut down now is that it did not win a contract under the backup supply auction that took place at some point. This infers that some other generation plant did tender for the required capacity and win - so the total capacity in the market place has not dropped. Instead, Cottam shut down today because their contract ended, but another provider's contract started at the same time. I would guess one of the newer CCGT plants is now servicing the contract.

If the import of energy via interconnects is only occassionally and in relatively small percentages of overall consumption I cannot see the problem. Any idea of what percentage and number of hours/days its likely tu be used ?

See https://www.bmreports.com/bmrs/?q=eds/main    Interconnector flows.

the flow of leccy through the interconnectors is quite complex and needs a lot of studying at different times of the day. The cross border flows can be seen on here along with the co2 intensity.

As far as i can see everycountry benefits at different times of the day/yr   by selling their excesses and buying the shortages
