Those remaining power plants are in England, about 5200 MWe Gross.
Also Kilroot in Northern Ireland burning coal and olive / cocoa husk. ( It did when I last worked there). about 460MWe,

Coal is about to come back on the grid this afternoon. Almost no wind anywhere, solar declining and demand rising means coal is filling the gap this evening.  |

And here it is - coal back on the grid , 200MW for now. Let’s hope the wind picks up again ASAP.  |

Uniper likely used the run up as an opportunity to undertake the statutory test of the turbine over speed bolts and get it signed off.

Open circuit gas turbines seemingly produced the same amount of generation as coal did, yesterday. Even so, together they only produced 0.4% of generation (per the ‘real time British energy fuel mix’ site).
Clearly, with the much slower start up for coal generation, the OCGT production would have been far more energy efficient than for the coal,plants - especially at those lower outputs.

On one hand I thought it strange they started them up when there was still plenty of headroom in the max gas CCGT generation. But then I guess there are shaking off the cobwebs and getting them ready for the inevitable steep solar decline over the next couple of months.

I apologise if this a silly question, but do the interconnectors with mainland Europe form part of our trade agreement being part of the EU ?
Without any trade agreement when the transition agreement ends, will the interconnectors be ‘turned off’ ?
Maybe we’re readying all our generating capacity as contingency ?

I read that with the insane temperatures yesterday, the gas thermal generation plants that were running were all struggling with reduced efficiency, hence needing to bring other stuff up online. Of course we still have that one entire nuke plant switched off, and there was less hydro available as it's been so hot and dry as well. Interconnectors will still form part of the UK supply (and export potential) but the terms of how that electricity is bought and sold will be very different (ie. worse). https://www.gov.uk/government/publications/trading-electricity-if-theres-no-brexit-deal/trading-electricity-if-theres-no-brexit-deal |

Great Britain's record coal free run continues to get longer and longer.
As of 15.12 today it's been 10 days straight (240 hours) without coal.
The first week without coal since 1882 was only a few weeks ago and now we’re on the way to a fortnight without coal.
Could we see the first coal free month this summer?
Possible in summer months (unless heatwave induced air conditioning becomes popular!) However, fossil gas imports from Qatar increased with each coal plant decommissioning. Especially in 2016. Given mild winters of late should continue to reduce coal overall. |

Oh Yes,
That nice trustworthy man Mr Putin is propping up his mate in Byelorussia, whilst his regime denies poisoning the leader of the opposition whom lies in a coma in Germany. Germany under pressure not to sign onto Nordstream 2 gas pipe line.
Crikey, the EU are delutional to base their energy policy on just renewables and gas supply from Russia.
