Seems to have been a big drop (ramp down) in Nuclear power at 5.30 ish today? (About 1.2Gw)

Had a look on the status page and cannot see anything to suggest why or where yet - but maybe the page doesnt get updated in real time

https://www.edfenergy.com/energy/power- ... y-statuses

Its the first time i have visited the status page for a while and was a bit of a shock how short the station list is now that Dungeness and Hunterston are off the list.

Dropped even more at 10.45 last night. Seems strange when CCGT is so high.

Definitely something amiss, I wonder if thy have hit problems with bringing Hartlepool unit two back up to full power and had to shut down again ?- that said on its own that unit would not account for the 1.2GW you mentioned so there has to be another station with both units offline which would suggest either Heysham stage two , Torness or Sizewell.

It will take EDF some time to sort out whats going on and get themselves set up to attend to the situation and only then will we get a played down version of whats going on.

Hopefully nothing that cannot be fixed quickly

I noticed this too, and could not understand at first but the status messages of each station are now several days old probably because of Easter. Looks like maybe another major breakdown as there are no imminent planned outages mentioned.

My own recollection of the nuclear industry is things tend to go wrong on night shift or bank holidays as the day maintenance teams are not there.

At the moment it's down 1.84Gw from yesterday afternoon, that's about 3 reactors or about 1/4 of our nuclear!

Mystery over, page updated.

Sizewell B completely offline - Unplanned automatic trip. Cause being investigated.

And Torness Reactor 1 offload refuelling.

Heysham 1 Reactor 2 on planned outage we already knew about.

Don't like to be spamming my own link but if you are curious in future which plants specifically are running or not (and not just nuclear - you just drill down by clicking on a fuel type) I built a thing: https://terravolt.co.uk/uk-grid-visual/
Won't tell you the "why" part - but it does update far more often than the EDF page.
