@_AlRuddy @amuse 💯 they are allowing America to use their airbases to bomb Iran, have sent aircraft for defensive operations in the gulf and have offered two aircraft carriers (rejected by the US president as “toys”). I am sure they will dig you out with minesweeper as well.

@LivvyJohn Nuc is basically constant, what the Pie Chart shows is a general reduced electrical demand, not increasing Nuc generation. Hence Nuc making up a higher percentage. I know charts can be confusing.

According to the SNP, Scotland doesn’t need new Nuclear. And yet this morning more than half of Scotland’s energy is coming from nuclear. Make it make sense.

@staylorish It’s contractual arrangements via the UKGov delivered by NESO UKGov does keep stating that renewables are cheeper. Hope that helps why the ScotGov cannot answer the FOI, it’s not devolved, not in their control.

On several occasions I have submitted FOI requests asking Scot Gov to identify generation assets in Scotland (even just one) which are producing cheap electricity. Every time, the response is the same: we can’t do that. The reason is obvious. The SNP rhetoric is fraudulent.
The SNP@theSNP

Scotland makes loads of cheap, clean energy...but Westminster keeps our bills sky-high. Vote for lower energy bills with independence. Make it both votes SNP on May 7th.

Berwick Bank will produce electricity costing substantially more than the wholesale price we are paying in today’s Ofgem price cap. Can Angus Robertson explain how this is consistent with the SNP’s election pledge on energy bills? No. Of course he can’t. An embarrassing answer.

@staylorish Weird how the electrical generators have not spotted you outstanding insight, and keep putting them where the wind is most consistent. You should also let NESO know and they could save billions upgrading the grid in Scotland. What makes you think you know more than the experts?

Of course the transmission charging regime is going to disincentivise generators from locating behind a grid bottleneck, and incentivise them to locate in front of that bottleneck, close to demand. It’s not exactly rocket science. And it’s not “unfair”.

The performative stupidity of the SNP transmission charging grievance. Yes 5.5 GW of ScotWind projects have been paused or cancelled (those lease options were *not* sold off on the cheap). But that’s because there is a massive grid bottleneck between Scotland and England.

@LivvyJohn You’re not grasping percentages or electricity here. Nuc electricity, is almost constant. AC electricity must be used at the same time it’s generated. We are using less power and you can’t turn off a nuc station, but you can turn off wind gen (Curtailment). Hope that helps.

For Scottish nationalists saying scotland doesn’t need new nuclear here is the current live generating data for Scotland. Nuclear keeping a third of the lights on.

@stuartpowell @mwt2008 You don’t even understand (or grok doesn't) the term curtailment “when the wind is too strong”. Either way it was wrong in the first few lines, gave up after that.

I asked Grok for an explanation of the contribution of wind power in the UK energy market in the context of the subsidies paid to wind farms when the wind was too strong (curtailment). I had to read the explanation twice before understanding that it was grid capacity for distribution that appears to be the inhibiting factor. Long explanation follows. Solutions and Outlook NESO and government are accelerating reinforcements (new HVDC links, onshore upgrades, "SmartValves" for dynamic line rating, etc.), with several projects due online by 2028–2030. These should materially reduce (but not eliminate) constraints. Other mitigations include more battery storage, demand flexibility, hydrogen production in constrained areas, and better locational pricing signals. Without faster action, NESO has warned balancing costs could reach £4–8 billion annually by 2030. In summary, curtailment is a symptom of mismatch between where clean, cheap power is generated and where the ageing transmission grid can deliver it safely. It is driven overwhelmingly by thermal transmission constraints at a handful of north–south boundaries, not by any inherent unreliability of the turbines themselves. The payments reflect both the need to keep the lights on and the current infrastructure lag behind renewable deployment. For the latest official data, NESO’s annual balancing costs reports and real-time BM data provide the deepest transparency. Curtailment in the UK electricity system occurs when the National Energy System Operator (NESO) instructs generators — overwhelmingly wind farms — to reduce or stop their output because the transmission network cannot safely carry the power to where demand exists. This is not because the wind has stopped or the turbines have failed, but because of physical limits on the high-voltage transmission grid.timharper.netIn 2025, this resulted in roughly 10–12 TWh of renewable (mostly wind) energy being curtailed in Great Britain — enough to power every household in London for a year — with total constraint-related balancing costs reaching about £1.46–1.5 billion. Of that, £363–380 million went directly as compensation to wind generators for turning down, while the majority (£1.08 billion) paid gas-fired plants in less-constrained areas to ramp up and replace the lost power. timharper.net Core Technical Causes: Grid Bottlenecks and Physics. The electricity grid must balance supply and demand in real time while respecting the physical limits of power lines, transformers, and substations. Key constraints include: Thermal limits (the dominant driver): Power lines heat up when carrying high current. If they exceed safe temperatures, they sag, risk damage, or cause faults. NESO therefore imposes "secure" transfer limits that assume the loss of one or two circuits (the "N-1" or "N-2" security standard). Exceeding these risks blackouts or equipment failure. ukerc.ac.uk Voltage and stability limits: High flows can cause voltage instability or insufficient system inertia (resistance to frequency changes), especially with inverter-based renewables like wind replacing spinning synchronous generators (gas/coal/nuclear). Regional imbalance: Most new wind capacity (onshore and offshore) has been built in Scotland and parts of northern England/East Anglia, where wind resources are strongest and planning/land costs were historically favourable. However, the bulk of UK electricity demand is in England (especially the south-east around London). Power must flow long distances southwards, but the transmission infrastructure was originally designed for large centralised fossil-fuel plants located near demand centres. The main pinch points are known as boundaries: B6 boundary (Scotland–England border): The critical "bridge". It has two main onshore AC corridors plus the Western HVDC Link (a 2.2 GW subsea cable), giving a nominal secure transfer capacity of around 6–6.7 GW. When Scottish wind output exceeds what this can carry safely, curtailment kicks in. ukerc.ac.ukB4 boundary (within Scotland): Separates northern and southern Scottish transmission zones. Many large new offshore wind farms (e.g., Seagreen in the Firth of Forth) and northern onshore sites sit north of B4, so power must cross this internal bottleneck first before even reaching the England border. Its secure capacity is only ~3.4 GW. theferret.scot Other contributing factors include: planned outages for grid maintenance and upgrades: These temporarily reduce available transfer capacity, worsening congestion even in moderate wind conditions. Forecasting errors: Sudden high wind or deviations between day-ahead forecasts and real-time output force rapid re-dispatch in the Balancing Mechanism (BM). Interconnector and export dynamics: High wind can coincide with export needs or flows that exacerbate local constraints. How Curtailment Actually Happens: operationally Wind farms bid into the day-ahead and intraday markets, often expecting to run at high output. In real time, if flows approach boundary limits, NESO uses the Balancing Mechanism — a short-notice market where generators submit "bids" (to reduce output) and "offers" (to increase output). NESO accepts the cheapest bids first to turn down wind (often newer farms with lower "lost revenue" costs) and the necessary offers to turn up gas plants south of the boundary. Wind operators receive compensation (via BM payments plus any top-up to cover CfD or Renewables Obligation income they miss). This keeps their business case intact but does not deliver the electricity. Consumers ultimately pay via BSUoS (Balancing Services Use of System) charges on bills and the replacement gas costs. Some large Scottish offshore farms (e.g., Seagreen) have seen very high curtailment rates — occasionally over 60–70% of potential output in peak periods — because they are "behind" the worst bottlenecks and can bid cheaply to turn down. theferret.scot Why It Costs So Much (Double Payment Effect) Wind is turned down → paid compensation (typically 24% of total constraint costs). Gas is turned up elsewhere → paid a premium (often 30%+ uplift because it's short-notice, and wholesale prices may be high) — this is the bulk of the cost. No fuel is saved on the curtailed wind (it has zero marginal cost), but gas fuel and carbon costs are incurred instead. This is why total constraint costs (£1.46bn in 2025) far exceed the direct payments to wind farms. Why Has It Worsened? Wind generation doubled in Scotland over the past decade while major north–south transmission reinforcements have been delayed by planning, consenting, local opposition, supply-chain issues, and long construction times (new lines often take 7–15 years). Renewables growth outpaced grid build-out. In 2025, curtailment volumes rose ~22% year-on-year despite some cost moderation in parts of the year. edie.net Yawn!📷From From timharper.net

Right. That’s why even by European estimates, you would have to spend one trillion euros and increase defense spending to 10% of GDP, just on conventional forces to do what we have done for Europe, without including nuclear deterrent. That would cost even more. So what would you cut to pay for it? Your healthcare? Education spending? What cuts do you propose?

Fox News: “So far, Germany, Italy, and Japan have said they will not send ships to” the Middle East to help keep the Strait of Hormuz open.” Lawrence B. Jones: “Well, they fell for the trap because, as the president said during the press conference yesterday, it’s almost a test. He goes, do we really need them? No, but he goes, I kind of want to see what they’re going to say to us. Are they going to be there—and they’re kind of proving his theory.” Cut off all funding to these countries!

@HomeoftheM @cryptodaaddy @tomhfh Except Fracking - local tremors No fracking -no tremors It does look like causation or the only other option is: that bit of earths crust flared up just at the time fracking started and stopped at exactly the same time it stopped. Anyway it’s now band by UK law.

TRUMP: "The United Kingdom produces just one third of the total energy from all sources than it did in 1999. They're sitting on top of the North Sea, one of the greatest reserves anywhere in the world. But they don't use it. And that's one reason why their energy has reached catastrophically low levels, with equally high prices."
