Apparently this has tripped again and a number of services are delayed/cancelled/stranded? - Does anyone know the cause?

Not sure if it's linked, 91111 was removed from service this morning at Leeds with pantograph damage immediately after arriving from Kings Cross.

9J30 was stationary for best part of 2 1/2hrs between New Barnet and Hadley Wood on UM but now on the move. Not sure if it was just unfortunate timing or is implicated

I would say maybe a lightning strike but it hasn't exactly been stormy, just consistently wet in my part of London. The OHLE has tripped several times (and finally didn't renegerise) with no clear cause & trapped trains didn't report anything untoward. Services all seem to be moving (albeit slowly) now though.

At this point, it might be the most likely cause but investigations seemingly still under way.

The grid is struggling recently. Very little wind has left them short of generatiing capacity. The wholesale price of electricity is sky high. And we are burning coal to make 1.21Gw of power. And open cycle gas turbine, which is inefficient, and usually only called on when struggling in winter. Maybe the voltage/frequency is getting unstable?

Nothing to do with it. My guess is that it will be an as yet undiscovered fault somewhere in the Barnet area, probably related to the heavy rain we had earlier (20-25mm in 8 hours today).

Maybe we need to employ some DeLoreans to boost the power...

Apart from Ratcliffe that has had an increase in workings of coal from Immingham is there any other power stations that could be switched on at short notice?

West Burton Coal is being called into action as well but NG can call on plenty of units this time of the year and even resort to demand side reduction from industrial consumers that turn down power demand and get paid to do so. It also has 100's of diesel peakers scattered all over the country that can be fired up if its really desperate. The power issues earlier are not related to the grid outage of a couple of years ago this was a NR infrastructure failure.

According to Tuesday's Guardian, payments last week included West Burton and a coal unit at Drax.

Off topic: The Gridwatch site makes interesting viewing, first time I have come across it, thanks for sharing.

Interestingly the substation at Sellinge where the power feed from France joins the national grid had a fire there today. Initial reports suggest the feed will be out of action until well into october

seems to be limited to 0.99GW now as from about 2300 yesterday 15/9/21. So thats about 1.5GW input lost.

National Grid was forced to evacuate staff from the site of the IFA high-voltage power cable, which brings electricity from France to a converter station in Kent, where 12 fire engines attended the blaze in the early hours of Wednesday morning. https://www.theguardian.com/busines...ortant-power-cables-in-midst-of-supply-crunch

IFA1 is off line so its 2 GW lost what left is IFA2 which is different. 1GW was off line for mtce the other 1GW will be offline for a month apparently. The coal boys are picking up the slack so they better be onto the FOCs to get more coal hauled in its going to be a busy winter.
