Probably the simplest solution is just to not pay for curtailment. If you build your wind farm in Scotland then you just have to accept that you aren't connecting it to an "infinite demand" grid. I think people have also suggested paying for electricity based on the location in the UK but the grid financial system is already so insanely complicated due to Thatcher's energy privatisation that making it even more compl…

It would make sense for energy to be given away locally before we have curtailment used. Why is that not a thing?

Because curtailment is about the available pickups not being able to take the energy. If you had a sink for it, you wouldn't be paid for curtailment so long as it was send through the grid. I bet if you used an alternate local grid the grorious (sic) (in)efficiency of capitalism will figure out how to be paid double.

A family member lives on the Outer Hebrides of Scotland. There is a community trust on one of the islands which has built wind turbines. However it took about 2 years before they were certified and connected up to the grid, and rather disappointingly it hasn't made local prices cheaper. The electricity is sold to the grid and that money goes to the community trust. Which seems bureaucratic? I wish we could have decen…

But we do have decentralized grid generation. What we do not have is fixed price transit rights and the ability for smaller generators to make direct deals with local customers. If I put up a lot of solar panels I'm not even allowed to give my electricity to my neighbors, they have to buy it from the grid which I am allowed to sell it to at a stupendous discount. The so called free energy market has mostly failed, it…

Out of interest, what would happen if you were to sell/give it to your neighbours anyway? Is it a slap on the wrist, or are we talking of multi-thousand pound fines?

I ask because whilst I believe there are no doubt (probably very strict) regulations around the selling of electricity, I wonder how enforceable they are on the average Joe. If I were to run a cable to my neighbour and just deny I was sharing my electrical store, how far would they go, and who would _they_ even be?

The UK has notoriously long build times for new power lines which heavily contributes to this problem. I think the FT said a new connection for a big user or power supplier often takes ten years, with planning alone now reaching 4.5 years and half of all new connections getting sued, which is insane considering the productivity loss and how it’s a already known problem. Sadly the government seems dar more interested…

NIMBYs dragging things down as usual They would probably object to battery installation next to the generators as well

They do. A "battery farm" in my area was recently vetoed by the council despite being approved by planning. However, the government has just overridden the council so it's back on.. for now.

I think a big problem with the UK is how many "layers" there are for such a small country and how each layer has its own processes of appeal. So you have to get past the local residents, past the planners, past the local council, past the county council, and past the government (not to mention the local MP, if they decide to get involved!) before anything happens when, historically, a more top down approach would be taken to get things going quickly.

I wonder how practical it would be to build a system that would let home appliances cheaply overuse energy when there is a peak in wind or solar production. For example: * Let heat-pumps heat homes to say 23C instead of 20C * Let freezers decrease the temperature to say -30C instead of -18C * Let electric water heaters heat water to say 70C instead of 50C, such water can then be mixed with more cold water Such overus…

For heatpumps/heating in general - we have a after market-product here that you can install in your old "dumb" central heating system - you connect it between the outside thermometer and your boiler/pump/what have you. It then fiddles with the outside temperature readings as to trick the pump to run harder/easier depending on the electricity price (and thus in extension, towards peak production). I used it in my previous house and it worked well! (no affiliation except as a former customer, but the product in question _I used_ is called ngenic tune [0])

With flexible rate agreements, that's already possible, and some DIYers already are doing this - the problem is the interfacing. Heat pumps (and central heating systems in general) are notorious for being walled gardens, most freezers run on analog technology (i.e. a bi-metal strip acting as a thermostat).

The only thing you would have to do to make this happen is to change electricity pricing from a fixed rate to a dynamic rate based on actual market conditions, along with a standardized way of accessing current pricing. This would drive consumers to shift their behaviors to take advantage of cheap prices, and smart appliances could access the price feed to make decisions like the ones you mention. Another simple one is washing machines, dryers and dishwasher offering to delay their start time to coincide with the cheapest energy price within X hours.

The issue is that most consumers don't like unpredictable prices. You can make a crude approximation by having 2-3 fixed rates for different times of day, but that leaves a lot of potential on the table

What is this percentage-wise? Every technology will have some waste, and obviously it should be minimized if economical. But I think the efficiency is more important than just raw waste numbers. How much energy gets wasted putting energy into and out of storage, how much on solvable transmission inefficiencies, etc. Is this the lowest hanging fruit?

A quick search points to: https://tamarindo.global/insight/analysis/uk-storage-need-in...

Which claims curtailment is about 10%

That's not nothing, but could also just be the cost of doing business. If you stop building when curtailment occurs at peak wind, you'll have less cheap energy when wind isn't at peak.

Imagine if wind slowed down all across the country because of wind turbines. The long term effects would be less soil erosion and less mountain erosion and water turbulence. What would the short term effects be? Bird populations will find it more difficult to travel long distance with fewer winds? Temperatures would sore in some places while dropping in other places? Pollution will become more stationary instead of being distributed and diluted?

What is the critical point of build out that would have such visible effects?
