I was at a conference last year where one of the speakers was from National Grid. Not only these morons had in mind that electricity demand should decrease (even before AI, it was obvious that demand would go up as we are moving away from fossil fuel with both heating and transportation going electric).

But their great idea to deal with the shortage is intermittent availability of power. You won't be able to wash your clothes when you feel like, you will have to adapt to when there is spare power, like in developing countries. This is just a regression in technological progress.

I saw the same messaging in France where the current president started his mandate with a grand programme to switch off a third of nuclear power plants.

If anyone thinks adults are in charge, let alone engineers, you are greatly mistaken.

For a long time (several decades) electricity demand has been decreasing in the UK, largely due to efficiency improvements. But now days pretty much everyone agrees that electricity demand will increase significantly in the future due to electrification. The UK has been planning for this for some time so if this guy was really from National Grid, he sounds like a bit of a rogue!

> "their great idea to deal with the shortage is intermittent availability of power. You won't be able to wash your clothes when you feel like"

No, nobody is suggesting that the grid will ever cut off power to anybody - certainly not domestic customers. The idea is that in a smart grid, big industrial customers often have the ability to temporarily reduce demand for heat or cooling or whatever. So if there is a signal from the grid that demand needs to be cut, automated industrial systems can (and already do) do that. The same goes for your car charging, water heating, etc. These things can automatically slow down during demand peaks in response to a signal from the grid, and you probably won't notice or care. You'll still be able to wash your dishes any time you want!

This is all definitely a good thing. A huge part of the cost of running the grid is in handling the biggest demand peaks, which might only occur for an hour or two per day a few times per year. If the peaks can be reduced and demand becomes smoother, then energy becomes cheaper.

I'm making the assumption that by National Grid, you mean the UK's electricity system operator, with National Grid (private company) being replaced by a NESO (public company).

> had in mind that electricity demand should decrease

Does this mean the speaker wanted demand to decrease? The UK forecasts from the Future Energy Scenarios [1] show demand increasing (see page 21).

> intermittent availability of power.

I'm assuming this was related to demand side response. Page 37 of the Future Energy Scenarios pdf contains an overview of this.

I worked at an EV smart charging start up (Kaluza) between 2019-2022 and my experience doesn't line up with a couple of your points:

> You won't be able to wash your clothes when you feel like

During my time at Kaluza the customer could charge their EV whenever they wanted.

> you will have to adapt to when there is spare power,

The customer set their minimum state-of-charge (0-100%) and we would always have it charged to that amount by a specified time, irrespective of demand. We aimed to charge the customer's EV when demand was low (there are UK markets we can sell this ability to - these markets may have changed since I was there), which would save them money, but meeting the minimum SoC was the most important thing.

> This is just a regression in technological progress

Reducing peak demand reduces the amount of infrastructure you need and makes better use of what you have. IMO it's a good upgrade that makes much better use of the assets on the grid.

Vehicle-to-Grid (or Home) charging takes this up a level by feeding power back to the grid. This "What’s next for Vehicle-to-Everything?" PDF [2] is 4 years old now, but has some good data on V2G and the benefits it brings.

There's a weird "degrowth" mindset that has taken hold in progressive circles in many countries lately. I don't understand them at all, trying to communicate with them is like dealing with an alien species.

I've seen proposals that are less intermittent availability and more incentivized pushing of consumption towards periods of lower demand. We already have all these computers in our appliances, might as well let them do reasonable things ... your freezer probably does a self-defrost cycle triggered by a timer and/or a door open counter, but why not wait up to X hours for off-peak pricing to do it. Or push the set points down a degree or two during off-peak pricing, to reduce energy use during on-peak. Also works for HVAC subject to user comfort, and water heaters if you're careful and avoid high temperatures that cause injury or low temperatures that allow microorganism growth.

Of course, that's science fiction... all the communication in appliances is designed to collect data and serve targeted ads. :( So very few appliances know if current pricing is peak/off peak or when it will change.

The Tories sold off the national grid, it’s a public listed company now. They don’t want to build infrastructure, they want to maximise shareholder value.

Thiel might have been right about the greens - the degrowth is so anti-human and destructive to society.

You won't be able to wash your clothes when you feel like, you will have to adapt to when there is spare power, like in developing countries.

Firstly, that doesn't sound like a particularly hard thing to accept if it genuinely helps. "I want to use my washing machine whenever I want" sounds like a very poor reason to destroy the environment.

However, regardless of that, this isn't new. There have been time-of-day based electricity tariffs for decades that are aimed at incentivising people to do more demanding things at particular times e.g. when industry isn't using the power. For example, https://en.wikipedia.org/wiki/Economy_7

Thanks. We have insane stupid politcians in charge of our energy, like the Tories and Ed Miliband who recently failed upwards into the Foreign Office. These guys couldn't care less about consumers and are obsessed with the enviroment and carbon.

On the surface it sounds like a good thing to worry about the enviroment, but in reality government policy is insane and stupid. As one example, the UK in it's wisdom don't allow North Sea oil extraction, the Norweigans do. And guess who we are buying electricity from? On top of that, the UK's overall contribution to carbon emissions are insignificant compared to China. We just pay more money for electricity for no good reason. Obviously we use less electricity, we can't afford it. And Labour enviromentalists see that as a win.
