It's subsidised via the litany of wonky markets that the UK has set up. Who decides how much money the wind farms get when we tell them to turn off? If that arbitrary amount of money were lower, would the night rates not be flatter? But if it were lower, then the windfarms would have less incentive to build... It's a subsidy. An indirect one, but a subsidy nonetheless.
The same with the other bonkers markets designed to slosh public money into the trough.. Who pays the CfDs? NGESO does (i.e. we do). Who pays the capacity market? NGESO does. (we do). Who pays Drax's tree-burning subsidies? (we do). Who pays for the carbon credits? (we do). Who pays the curtailment costs? (we do). Ofgem invents all these "markets" and pretends that it's free-market economics in action. It isn't, It's just a less-efficient form of subsidy, and one that's harder to follow the money to find any corruption that may lie behind it.
Also, many tariffs are directly subsidised by other tax/bill payers, and i'd be surprised if you weren't using one with your eco green set-up. Heat Pump tariffs for example where a portion of your HP usage is subtracted from your bill.. Solar feed-in tariffs, v2g tariffs, DFS events, these are all directly susbsidised.
> Imagine if we have EVs rolled out - you'd never need to curtail output at a wind farm again
Except we still would, because we have a massive transmission bottleneck, especially between England and Scotland. How do we get NGESO to build more pylons? Apparently we can't, because the nimby's don't like them, so we will invent another market for companies to build subsea HVDC links instead e.g. the recently approved Eastern Green Link and the 80-odd GW of projects waiting for approval. They are very expensive, unreliable, prone to sabotage, they don't contribute to synchronous stability of the grid (if anything they destabilise it and cause islanding), but who cares, we have outsourced all of that risk to the private sector, right? As usual the economists have ruined everything.
> but sometimes..
In a hot country where most people use Air Conditioning, then LED lights are a massive win. In the UK, we have our heating on for most of the year and turn it off for a few months in summer when it stops raining.. You might have no change in comfort, but that's because you have a thermostat.. When you have no extra heat sources, your heat pump has to run harder to maintain your setpoint, so you don't get a 95% reduction even if you really did have 10x 100W bulbs on all at once and have replaced them with 5W LEDs.. (btw I find that a 5W LED is nowhere near sufficient to replace a 100W bulb, I need at least 15W) and the crest factor on those LEDs is abysmal. You may find that your smart meter charges you more for a 15W LED than a 100W incandescent, because the peak current is higher.
Your heat pump may have a COP of 3, but due to inefficiencies, costs and dodgy deals in the generation, transmission and balancing/settlement systems, your electricity costs 3 times more than gas anyway, (at the times when you need heating, at least). So might as well get a gas boiler and be done with it.
I'm not saying it's nothing, i'm saying it's marginal, and IMHO not worth the extra faff from a heat pump, LEDs, EVs, smart meters etc. They can pry my Bakolite electromechanical watthour-meter from my cold dead hands.
Anyway, always a pleasure arguing with you Mr Robson. Have dome upvotes and an e-pint :)
