Here is what I do not understand about these kinds of dynamics: Are they not the perfect way to encourage the creation of energy storage companies and technologies? It seems like there is a massive opportunity to purchase energy when it is cheap or even negatively priced, figure out some way of storing it, and then sell it back once the price is higher. Over time, this could stabilize the grid and encourage developme…
The UK is wasting a lot of wind power

I have the luxury of a 13khw battery, so it might make sense. But I suspect that when I need to use the grid will be uber peak £1.04 per kwhr. Edit: for those who are curious, here is some data on prices over the last month: https://agileprices.co.uk/
I guess you can’t have two suppliers, one on a traditional fixed contract and one on the octopus stuff, and choose the best one
Re: The UK is wasting a lot of wind power
#353If the UK were ruled, and all decisions made, by a benevolent dictator, then the solution to this problem is easy. Consider every option of where to build the wind turbines, and where to build power cables, add up the cost of every option, and choose the cheapest (environmentally and/or monetarily) that gives everyone the power they need. An ideal market would produce the exact same result right? Well not quite... An…

I don't have a strong opinion personally about the franchise system as I don't use any UK rail. My gut tells me they're not adding any value and they might as well be nationalised but someone whose opinion I trust (rail engineer and YouTuber Gareth Dennis[0]) has said that ditching them and nationalising it entirely wouldn't really fix what people think it would. However it has to be said that TPE and AWC have stood…
Yes both of those franchises are failing, and if they aren't meeting their KPIs then they should have the franchise stripped. Some of that is infrastructure (the cancellation of platform 15/16 at Piccadilly means the new Ordsall chord is basically useless, but they tried to use it anyway), I don't know enough about TPE to fairly attribute it, but with AWC it's franchise operation -- especially staff availability. Som…
The popular opinions I have seen are:
- “nationalise the railways”
- more frequent, reliable and cheaper services overall
As discussed, nationalising the railways isn’t necessarily the silver bullet many people think, but if you engage with those people and don’t insult/berate them they’ll come round easily. They're not hardline communists, hellbent on the destruction of private companies - they just want better train service somehow and may not fully understand how to get there. That's not to deny the existence of "tankies" and other weirdos, they're just a very very tiny minority.
HS2 should enable the “more frequent” part over the regions it covers. I don’t know how to make services cheaper or more reliable, I imagine subsidies come into it somewhere though, and this inevitably means that yes someone wealthy at some point will benefit from a cheaper rail ticket.

> Surely HVDC links between Scotland and England could be built? why would this be necessary when the entirety of Great Britain is one synchronous grid?
Strangely there already is one between Scotland and Wales and two more are proposed (see the article). I suspect NIMBYism is a big part of the explanation. Airborne AC links are efficient but ugly. Underwater AC links are tolerated by Nimbies, but inefficient. So you end up with underwater HVDC links.
They are expensive things, and typically not something left to popular vote.

Hydrogen electrolysis and increasing interconnects seem a more useful thing to do.
I haven't followed the technology very closely, but it was my understanding that large scale storage of hydrogen isn't here yet, if it ever will be? And even if you built out more transmission, you're still limited by how far you can go. On top of that the infrastructure needed to transmit over large distances (1000km) is huge. Then there's a bunch of regulatory red tape to cut through, NIMBY push-back etc. It's unli…

Because the wind providers have already sold that electricity in an energy auction. So the grid has to pay them for electricity, even if they can’t use it. One of the big points in the article is that there’s a single energy market in the UK that doesn't consider location. So it’s possible for wind providers to sell energy from locations where it can’t be used. An obvious fix is to introduce multiple energy markets f…
This isn't a real economic loss. Claiming it is, is tantamount to saying that if you don't need to go to hospital while on vacation, you have wasted money on travel insurance.
Perhaps the system could be changed to be more like how you imagine it should work, or would prefer that it would work.
But not understanding how it does work and jumping off from there on the discussion means that folks end up talking past each other, rather than actually communicating.

Also a lot more expensive. The UK is not big enough for it to make technical sense.
> The UK is not big enough for it to make technical sense. The UK market maybe not, but the UK could make a truckload of money selling their wind power to France to aid their old, barely running NPPs.
Re: The UK is wasting a lot of wind power
#360Negative prices on power i.e. curtailment, is the perfect use case for Bitcoin mining. Obviously there needs to be some amount of battery storage of energy too, but once the storage capacity meets the needs of the local grid, and the batteries are full... what do you do with the excess power? May as well mine Bitcoin with it and make some profit on that excess energy. Energy buyer of first and last resort.
