Cold and Still

Last time I looked a day was 24 hours... what you getting from your PV now harry (8pm)

or cold and dark as it probably is now when the PV contribution might actually be of some use.

Lots of the small scale PV won't even be counted...

"energy too pointless to meter"

ether the other 5GW of coal or the other 5GW of gas..??

Square root of sweet fanny adams after dark..

maybe 500MW by day in winter

solar and some wind is 'negative demand'

You can see faint midday dips in the summer.

Looks like they wanted to flush the pipes out good and proper tonight, they gave it a final burst of 2.66GW, total for the day over 13GWh. Still no wind, so it's up to fossil and nukes to pump it all back up again overnight. The demand today was over 1TWh.

They have no means of instantaneously metering it.

Some figures here. Note rate of increase of installations.

It's about saving fuel/pollution and is only part of the solution. Plenty of retards here can't get their brains around this.

So what's the installed capacity now, a little over 4GW?

And on a "good" January day what will they produce? Perhaps 1GWh out of

1TWh and none of it during the evening peak.

Interesting link, thank you - even with the plethora of panels currently blighting some parts of the country the generation is still only 0.64% of total. I hate to think what the country will look like by the time that figure gets up to anything meaningful.

I don't think it was pipe cleaning but an "Oh shit" moment, biomass took a roughly 400 MW drop at the same time. What had a problem and had to rather quickly (45 mins) wind down? It's back up by 1000, having taken about 6 hrs to do so.

At 1900 hydro also picked up and though hard to see due to the scale CCGT also picked up.

Demand? Consumption surely?

The jury is still out on that one. Given that for every installed Watt of intermittent wind/PV you have to have a Watt of dispatchable plant running at less than optimum efficiency to even out the fluctuations.

Throwing gratuitous insults is one of the signs that some one knows they are losing their argument.

tonight,

Been looking a bit closer something happened. Not only is there that big spike in pumped, Hydro, CCGT and Coal all show a pickup and the OCGT that had gone offline about 1915, came back at 1925 at 110 MW until 2015.

"Looking a bit closer" meant I grabbed the 6 hours of data from 1500 to 2100 yesterday from Gridwatch. Brilliant that you can now select the time period of interest but even though I selected "All" I don't have a "Biomass" column but do have "Other" that looks as if it might be Biomass...

The extra 5GW demand which appeared yesterday morning is still there, superimposed on the regular daily load pattern. I wonder what it is?

The installed capacity is only 0.65% of the total consumption - the actual generation is going to be at best only 20% of that installed capacity.

This is apparently starting to cause problems in Germany. They have been talking about reducing/stopping any more fixed south facing panel subsidies, and maybe encouragng fixed east/west facing ones.

I often mused on the thought of a rotating roof.

Wind is much less than predicted today, we are exporting a lot to Ireland and not importing much from the continent at the mo. Open cycle already fired up. Tonight might be the night for anything interesting to happen!

And tomorrow - it's a very cold couple of days on the forecast doon sooth - minus temperatures most of the day.

Clearly a system that is designed to cope with fluctuations in demand cannot cope with fluctuations in supply. Simples
