I've been offline for a bit. I got involved in something pointless, then along came a proposal for a damn great big solar farm between my house
and the nearest pub - so I've been crunching data.
The first thing I found is that there are some errors in the data in Gridwatch. (the real one, not the commercial copy). Enough errors that I couldn't use the data to work out what is going on.
I've got a partial filter - but it's not enough, so I ended up using
data from NESO instead. NESO don't publish as much information, but they
seem to be reliable, so I used them for my conclusions.
My filter for the gridwatch data says:
Ignore a line if:
- The frequency is zero
- The demand is zero
- The demand has risen by more than 50%, or dropped to 2/3 of the
previous value
- The demand and the frequency have not changed from the previous one
Sometimes the data is the same for an entire month at a time :(
My conclusions BTW are that solar power - even rooftop solar - is a
complete waste in this climate. It cannot help us to reach the
Governments "Net Zero" target, nor can it do anything useful.
The reasons?
If you look at the demand for power it's highest in the evening, and in winter.
In winter in the evening it's dark.
That means we need something else to make the power then.
If it works then it can work any time.
Incidentally right now solar _does_ do something useful - on the days
when it is sunny they can throttle back the gas. But that won't be the
case if we are using the less than 5% gas that "net zero" requires. By
2030.

My electricty consumption is pretty even throughout the year (gas CH).

If we use more power in winter than summer, wouldn't it make solar even
less attractive when the standing charge goes and the cost per kWh
increases to compensate? Solar would make even less of a contribution to energy costs at that time of year. It would make a higher contribution
in summer, but unless a lot of air-conditioning was used, it wouldn't compensate for the higher winter usage.
Link the solar to a storage battery maybe?

ah - but if you have big (gynormous) batteries there's no problem ;-(

Right now storage is one of the data reported. The maximum output from
all the storage in the entire country over a day is about an hour's consumption.
If you look at a bad week in the depths of winter solar does **** all
even in the limited hours of daylight, which means we'd need enough
storage to maybe last a month (guessing here).
If we had that much storage it would be better linked to wind farms.
They're even uglier than solar farms, but at lease they produce more
power in winter when we need it.
If we install 2.6 times more wind farms than we currently have we can
get ourselves down to the 5% gas that "net zero" requires.
For solar it's 40 times, and when the sun does shine we'd have to turn
most of them off.

My electricty consumption is pretty even throughout the year (gas CH).
Mine was even too, which surprised me as I used an electric fan heater
to heat my study, rather than turn on the gas central heating for the
whole house.
It was only after buying smart plugs that I discovered my old Freezer
and Fridge both consumed huge amounts of energy in Summer (I let my
kitchen get cold in winter).
Hopefully, somebody somewhere would come up with a storage solution if we ever
got to that state. I was speaking to somebody the other day (an academic environmental scientist) who was getting excited about domestic thermal stores
for suitable properties (with cellars, in the main). Over my head but there could be something in it.

OOI - where is that reported? I think the figure relating to domestic with solar and storage installed would be interesting.

only. Of course that's not how the green press releases are phrased.
Teh amount of pure Horseshit spouted by the GreenCrap⢠lobby is enough
to power the country for a week.
The public narrative is for great strides forward towards 100% renewable energy - at least for electricity. The reality is that we are emitted
moire CO2 than if we had simplyt built more baseload CCGT stations
I was looking for a media piece about what Ed Milliband's big green plan
was up to. Instead I found a piece from The Telegraph that
unintentionally made Ed sound 100% sane.
<https://www.telegraph.co.uk/business/2025/01/08/ed-miliband-going-to-throw-away-brilliant-fusion-industry/>
I think it illustrates that the problems understanding energy are not necessarily Marxist, more that journalists and politicians have zero appreciation of technology.

Read the actual document, rather than filtered through the media. It's much better at presenting the numbers: https://www.gov.uk/government/publications/clean-power-2030-action-plan

You also see highly misleading political comments like "Putin turned off
the gas". Our politicians sanctioned Russian energy, rather than the
other way around. That is why gas prices went up. The latest story is
about Ukraine switching off their gas pipeline, Putin was willing to
continue supply.

Sure, if you like, but that is a bit of a shell game too. You might not
like Putin, but he didn't cut off the gas supply.
I find documents more trustworthy if they don't try to promote their arguments by distorting the truth.

Neither did the ukrainians. They simply refused to renew the contract, which has run its term.

I said our politicians sanctioned Russia. *Our* politicians chose to
block our access to cheap Russian energy. I can understand why they try
to divert us from noticing their responsibility for higher bills. It is
what politicians do. It is just that when I notice them doing it in an
energy plan, I know it is clearly a political document.
I'm not sure why you want to spin it so that the Ukrainians aren't responsible for decisions they took to limit other countires access to Russian gas. Prior to terminating transit via the Ukraine pipeline, they tried to block Nord Stream 2.
Putin does lots of bad shit, but making out that he is refusing to sell
us cheap gas isn't reasonable.
FWIW, if Trump invades Panama (or some other country), do you think we
should invoke sanctions against the USA? I would be against.
