Heavy grid loading today. Does anyone else think we are running dangerously near the limit?

Better not plug your EV in to charge just now.

On the 13th Jan residents in Alberta Canada were asked not to use any heavy loads such as EV chargers and electric space heating due to grid limitations.
To compound this I imagine the range on EVs will be right down due to a lot of the battery energy being used to heat the drivers and passenger cabin.
we are not even in the red yet,

My EV's were plugged in earlier, now I'm exporting from solar, doing my bit to help

I wonder if people on variable tarrifs are being charged more today?

I'm sure they will, I'm somewhat surprised that a saving session hasnt been announced as they did yesterday, it's a great way to earn money propping up the grid.

It's a little towards the high end of the scale, but not excessive by any means, I've seen higher recently (last cold snap end of November) My highest unit price today is 33.6p which is a tad more than those on the variable tarrifs, but the rest of the day has been mostly between 15p and 20p.
Windy weather on the way soon so will be better, probably won't beat christmas eve though....
The frequency gauge will indicate grid overload if it falls below 50Hz for any length of time without correction being applied. This will indicate that supply side demand has outstripped generation capacity and I'd expect they have a plan for this where they'll immediately shed some large industrial loads such as foundries to help with the balancing act.
Im glad we have a battery on the house then looking at the amount of grid loading that were upto

Me too, its been amazing on two occasions when weve had a powercut that we just carry on as normal with washing machine - tumble dryer etc, seems really odd when all of our neighbours are down to candles and camping stoves.
and i also have a backup generator aswell for power cut use

Yup, me too, I feed the genny into the Victron inverter which then provides the AC power to trigger the Growatt into action. The 3kW genny supplies enough to keep everything going with the inverters and batteries feeding into the mix to keep all loads supplied.

This gridwatch thing is way more entertaining than sat pm TV will be, thanks for this murdoch!

Hi John, hope you don't mind me asking, I'm curious how you connect the generator to the multiplus, I thought you could only do that with a quattro?
The other one thats interesting (and looks a bit more upto date, laout wise) is https://grid.iamkate.com/
Also check out national grid's carbon intensity forcast: https://www.carbonintensity.org.uk/ and interestingly someone has used the same data to make the should I bake forcast: https://shouldibake.com/ (he/she probably should rename it, "Should I charge the EV?")
A bit more light hearted, see the grid balancing game: https://www.nationalgrideso.com/what-we-do/balancing-grid-interactive-game gives a bit of an insight in to the challanges they face of keeping it in balance
Anyone know the total capacity of generation we have in the UK we have on a cloudy day?
I don't think anyone knows the solar contribution because much of it must be from private micro systems.
According to the notes on the website the orange band on the main meter is "renewables", but I don't think they declare their definition of that. e.g. It's presumably wind, plus their estimate of solar, but do they include nuclear, pumped storage or hydro? I don't think they say, or I've missed it.
Edit. I've just looked at it again, and I'm not sure that it makes sense. The orange band is only 5Gw, whilst the declared wind power alone is 15Gw this morning.
