There's quite a few of these. Here's another one that I prefer the UI of and I think is a bit clearer:

Don't most domestic panels actually feed into the grid (so presumably would show up on the stats as solar generation)? Unless you've got a battery system at home.
They do - but as the rate you are paid for electricity is now a fraction of the price you are charged, most people without a battery try and align their energy use with production. ( The suns out! Put on the washing machine/dish washer etc ).
Not if you locked in a feed in tariff from years ago. They lasted 15 years I think.

#53I'm guessing NordPool has something like that somewhere on their site (probably not as cool looking though), but what I found interesting is this:

It's the notifications for all production and transmission in Europe coming online and going offline with power and dates.

I really enjoy this one: https://app.electricitymaps.com/zone/GB
It shows energy sources for all of the countries in Europe on a map, import/export, prices and CO2 intensity.

Wind farm operators sell their power onto the market (they can sell however they like, but the reference price is calculated according to the day-ahead spot price). Any imbalance between the agreed price and the reference price is sent to the LCCC (Low Carbon Contracts Company, part of the government). The LCCC then re-charges any CfD payments or surplus funds to the electricity suppliers. This should eventually work…
thanks - very interesting! I think that also clarifies something I'd found confusing: that the spot price is currently effectively determined by the price of gas, and yet the UK consumer is benefitting from the presence of wind generation (which generates much cheaper power than gas) If I've understood your post correctly, this is because the electricity companies don't directly pass the spot price onto consumers. In…
Yes, that's right. The spot price is determined by the marginal source of electricity. That's normally gas, but is sometimes coal, imports, or pumped hydro storage. The consumer actually benefits twice - once when the wind is sold into the market, which necessarily lowers the spot price for _all_ electricity (more wind supply is the same as reducing total demand, which will reduce the market price). Then, the difference between the spot price and the CfD price is refunded, but this time only on the electricity actually generated by wind.
In general, electricity suppliers don't literally pass the spot price on to consumers. It used to be that a supplier could price electricity however they liked, including passing the spot price on. However, for the past few years, suppliers are required to buy futures, and price their supplied electricity on that basis, because of the domestic price cap. If they didn't they would run the risk of going bankrupt like Bulb. Futures bring stability, and in an efficient market with perfect information buying futures would be the same as buying spot. But the market is not efficient and with perfect information, so that assumption doesn't apply. Notwithstanding that, you were correct, the part of electricity generation attributable to wind should be taken account of at the lower price.
For most consumers, their marginal cost of electricity is identical to their average cost (ignoring the standing charge) as they are on a fixed rate tariff. It would undoubtedly be more efficient to charge consumers the actual marginal cost at the time of consumption, and then refund the CfD payments in a monthly payment later, but that's not how it's done sadly.

>No people to object about it I'm not sure whether this MP was in the pocket of gas, coal or nuclear interests or whatever but he successfully rounded up residents to NIMBY what would have been the biggest wind farm to date even though it would have barely have been visible. https://en.m.wikipedia.org/wiki/Navitus_Bay_wind_farm I was bitter before. Doubly so now electricity prices are through the roof.
Scotland has one of the biggest gas fields in Europe, why should it rely on ugly and unreliable Wind turbines? Esp Global Warming probably makes Scotland's climate more comfortable, and its proximity to Greenland means sea levels might even fall.
Our economies are linked, so even from a selfish perspective, the effects of global warming will felt even in places where the weather doesn't directly cause problems. If the effects of climate change get bad, we are likely to see widespread war.

In UK wind is actually broadcasted to take over. After the new line connecting with Norway (for hydro storage) the majority of investments are going into wind. On Nuclear, I think right now there is 1 big nuclear plan offline for maintenance so there might be some of that too. In the Mediterranean area, while there is more prevalence of solar, it's not a clear winner either. For instance in Italy there is quite an ag…
The Tories said no to onshore wind, now solar is getting really cheap they are banning the building of solar on most farms (by reclassifying low quality land as higher quality land that must be used for food). At the same time they are thinking about allowing wind on land again (probably because it will no longer be the cheaper option). Given their links to fossil fuel interests it comes across as delaying tactics.

That's actually changed as of this week https://www.bbc.co.uk/news/uk-politics-63880999

Re: GB National Grid Status

Agreed. But note that a lot of the local solar capacity doesn't actually show up on the grid production numbers. ie if you have a solar panel on your roof and mostly use it to reduce the power you take from the grid, all you will see in the national numbers is lower demand, not increased production.
Don't most domestic panels actually feed into the grid (so presumably would show up on the stats as solar generation)? Unless you've got a battery system at home.
Export tariffs are so low (around 4p per kWh) compared with import tariffs (more like 35p per kWh last time I looked) that if you got solar panels recently, after the feed in tariff was stopped, then getting a battery too made sense. I imagine most new installations include batteries. We only really export in the summer or if we are away - we use virtually all the electricity we generate most of the year.

#60On Friday, December 9th at ~4:00pm GMT (Greenwich mean time): Nuclear: 5.25 GW Wind: 3.84 GW Combined Cycle Gas Turbines: 23.31 GW Solar (Estimated): 0.35GW Installed Wind Capacity (onshore + offshore): 25 GW [0] Installed Solar Capacity: 13.4 GW [1] Total installed Wind/Solar: 38.4 GW. Total produced: 4.11 GW Wind is currently producing 15% of its installed capacity. Solar is producing 2.6% of its installed capacity…
There is a reason [1] why Solar is only generating a small fraction of installed capacity.
