Generally the prices betwen 4pm-7pm are expensive and the rest of the time it's cheaper - although with current world events things have gotten a little spicy lately.

On really windy days you definitely get to see the benefit where prices drop to zero or even negative, which is great if you have an EV or something to dump lots of power into. Looking at todays prices they're like 1-3p p/kWh!

But that doesn't last, as the wind dies things start to get back to normal.

The key with the tariff though is to just play the averages and generally avoid high power usage during the peak periods. My average for the last 2 years was around 30% cheaper (p/year) than what I would have paid if I was on a normal energy tariff.

It will be interesting to see whether that trend continues, especially with the state the world has suddenly been thrown into.

> Ed Miliband’s net zero targets are facing fresh scrutiny after Britain was found to be paying the highest electricity prices in the developed world.

> New data published on Tuesday showed the price paid by UK industry for power was 63pc higher than in France and 27pc higher than in Germany.

> Britain is also the second-most expensive country in the world for household electricity, with billpayers paying twice as much as those in the US.

In March, the UK emitted 161g CO2/kWh. France did 6 times less CO2/kWh with 2x less renewables !

Bit more advances in grid scale storage, bit more interconnects and this looks real good

One could work out what the discrepancy between consumption and production during the day to infer the battery discharge rate, but I don’t think there’s anything there…

There has been talk, seemingly power generation dispatch a year or so ago was do e by phoning up the power station and saying “More amperes please Mr Woodbine”.

My understanding is this is being written to an automatic system which isn’t fully commissioned.

Grid battery owners a few years go were irate that they weren’t in the offing to sell power. But that must be resolved by now, since so much money is being invested in it.

Unless that is for non-grid power supply.

By their own data, today is about 18GW for wind, and this time last week it was 3GW.

If you add to that deindustrialization and buying everything from abroad and not caring where that energy comes from, it’s super easy.

Headlines like this do nobody any favors. The problem with renewables is that you cannot run a grid on renewables alone. Many days will have an abundant oversupply, like the day shown. Many days will not. Consumers are not tolerant of brownouts in the west. We need pump storage hydro, we need massive improvements to the transmission system, and we need battery storage plants (in that order).

Its fine to celebrate days of high renewable GW output, but people get out the GW Bush 'mission accomplished' banners a little early. The generation is the cheap and easy part. The rest is expensive and slow and needs way more focus than it's getting if we ever want to make progress in the west (China is already figuring it out)

But there’s a generation surplus and export of +13.4%!
