Electricity That's Too Cheap To Meter
https://shkspr.mobi/blog/2023/12/electricity-thats-too-cheap-to-meter/

Nuclear power was sold to the world as a safe, clean, and economically viable source of electricity. We were told that it would be "too cheap to meter"1. Even the most ardent proponent of nuclear power will have to admit that hasn't come to pass. Construction costs for nuclear power stations are dwarfed only by their decommissioning costs. Yes, politics and regulation conspire to increase the price - but nuclear hasn't made electricity particularly cheap. Indeed, we mostly seem to be paying more than ever for our power.

Well, not quite.

On Christmas Eve, my electricity company emailed me to say that I would have several hours of free electricity. They would charge me £0.00 per kWh. More than that, at a few specific times they would pay me for my electricity use!

Here's the graph of my half-hourly prices:

Graph of electricity prices. Some are negative.

Most factories and heavy industrial plants weren't running the day before Christmas. UK power usage spikes when everyone boils a kettle at the end of a football match or other similar event - but there was nothing so momentous happening at 3AM. So supply outstripped demand.

Anyone with a smart-meter could have been paid to charge their car, run their tumble dryer, or stay up until the wee hours playing on their console.

And was it nuclear power which did this? No.

Dashboard showing electricity prices in the negative. Around two thirds of the electricity is being provided by wind.

As shown on the live grid tracker about two-thirds of the day's electricity came from renewables. It was pretty overcast, and our solar panels barely made 1kWh.

It wasn't mined uranium which gave us power which literally had to be given away; about 62% of the electricity came from wind.

At this point, the nuclear lobby will start whinging about subsidies (both nukes and renewables are generously subsidised) and how wind can't provide a base load (which is fair). But although sticking a bunch of turbines in costal waters is an engineering marvel - it's pretty cheap compared to building and maintaining a nuclear power station.

Wind - and other renewables - have done what nuclear couldn't. They have provided such an abundance of electricity that consumers are paid to use it.

History and the Future

It's worth looking at the original quote from 1954 about electricity becoming too cheap to meter:

Transmutation of the elements, unlimited power, ability to investigate the working of living cells by tracer atoms, the secret of photosynthesis about to be uncovered, -- these and a host of other results all in 15 short years. It is not too much to expect that our children will enjoy in their homes electrical energy too cheap to meter, -- will know of great periodic regional famines in the world only as matters of history, -- will travel effortlessly over the seas and under them and through the air with a minimum of danger and at great speeds, -- and will experience a lifespan far longer than ours, as disease yields and man comes to understand what causes him to age. This is the forecast for an age of peace.

As well as nuclear, he talks about "photosynthesis". Well, the UK now has 15.6 GW of solar capacity across 1,430,994 installations. A small part of that is my solar panels!

The UK also has around 27GW of wind capcity installed.

It is entirely possible that the UK will have generated the majority of 2023's electricity from renewables.

Because home appliances are increasingly efficient, domestic energy use is falling - it's down 19% since 2010. Electricity use by domestic properties was about 96.2 TWh in 2022 and 135 TWh was generated by renewables.

Yes, electricity is fungible, but you can convincingly make the case that every home in the UK was powered by renewables.

Solar panels don't work at night, and wind-turbines don't work when there's no wind. We'll always need something to be able to provide a base-load of electricity. That might be nuclear, or fossil fuels, or it might be storage from the excess power from renewables.

Sadly, the world is still filled with war, famine, and disease. But, for a few moments on a winter's evening, wind power genuinely became too cheap to meter.

Shameless Plug

If you want to move to a time-of-day electricity tariff, you can join Octopus Energy - if you use that link, we both get £50 bill credit.


  1. There is a lot of contention about that phrase. It was (probably) about the future prospects of nuclear fusion - but it became attached to nuclear fission. You can read more at the United States Nuclear Regulatory Commission

I’m on an energy saving kick.
So far this month between the hours of midnight and 8am we are averaging 1.2kWh per hour of use.
I can only account for a max of 400Wh/hr and even that is a high estimate.

No ac on. All computers shutdown.
The only thing running is about 200w of network gear, refrigerator and freezer. And some phone chargers.

Something is drawing power that shouldn’t be 🧐

Hold on a sec, weren't we all told that privatisation would lead to cheaper electricity prices?

Weren't we told that repealing the carbon tax would lead to cheaper electricity prices?

Weren't we told that sticking with (more expensive) coal and gas power over (cheaper) renewables and storage would lead to cheaper electricity prices?

From the ABC:

"At the heart of the price gouging inquiry, initiated by the ACTU and led by Allan Fels, is determining in a high inflation environment what's general inflation and what else might be influencing pricing behaviour, the main offending price gouging industries, how they do it and how it impacts everyday Australians.

"Part of the problem is Australia is awash with oligopolies, which means there isn't as much price competition as there might otherwise be, which helps explain why real wage growth has been low and why the real prices of so many goods are so high.

"And while most of the media attention has been on Coles and Woolworths, the report will include other sectors accused of customer gouging and breaching trust such as energy, airlines and banks.

"Sydney University professor Lynne Chester, from the school of social and political sciences, supplied the inquiry with a detailed submission ... [which] said electricity prices have been escalating since 2005, largely due to increases in the charges paid for the generation of electricity. She said the charge for electricity makes up a significant component of the electricity price paid for by consumers.

"A key issue was that the regulation was designed for a competitive market, assuming competition would deliver lower prices, but the market was never competitive due to the presence of big powerful generator companies that have been merging with retail companies to create giants such as AGL, Origin and Energy Australia."

No, you can't save £30 per year by switching off your "standby" devices

We had a 2kW heater plugged into a multi-socket lead which ultimately failed.

I took the lead apart to see what exactly had gone wrong.

Was just out for a night walk. I can't tell if my eyes are playing tricks, but I felt like I could see short flickers in the city light haze reflected off the air; kept walking, it seemed like it was happening in the streetlights too. Could there be something happening with the power grid?

okay electrodons I got a weird one

Standard single-gang duplex receptacle on a 15A circuit. Upgraded to code circa 25 years ago by pros known to do good work in general. (To be clear: not me.) It's in a metal box with wiring in metal conduit back to the panel.

Stops working. No drama, just stops. Everything upstream to the box is fine; the breaker doesn't trip. All looks well, just... no power.

Remove the cover. It is immediately obvious that there is loose plastic hanging around in the box.

Pull out the fixture, discover chunks of plastic have come off the side of the receptacle. It's broken away in multiple pieces with sharp edges, not melted. No burns near the damage, no external damage.

And so I ask:

What the fuck?

1 year of @edent_solar. We are 100% offset!

Our domestic solar panels have generated more electricity in a year than we have consumed.

We installed 5kW of solar panels on our roof in 2020. Half are East-facing, half West-facing.

Over a full year, they've generated 4,165kWh.

By comparison, the average UK household uses about 3,800kWh of electricity per year.

My 6-yr old asked one of the BIG questions the other day.

"Daddy, why do we live?"

Knowing that he's being influenced by the ubiquitous botherers, I responded:

"Because of , little buddy. Kind of like the lightbulbs in our house, we all have a in us that runs through our and . When that spark goes out, we die."

He thought a bit about that, and then came the next BIG question:

"What happens when we "?

I carried the analogy further and told him:

"We become a part of the electricity that runs through the entire that let's everything live. Which is super important, because without that electricity, nothing would live."

Long pause ... "And, is that , Daddy"?

I replied: "Well, nobody knows for sure, but a lot of really people think it is."

This is actually a long Twitter thread I co-wrote with an electrical engineer and energy grid expert in March of 2021.

But given Xitter's imminent demise, it seems wise to port it over here.
