I would desperately like to see UK government decouple the price of electricity from gas. We have just about the most expensive consumer energy prices in the world…but lazy journalism won’t get us there.

This piece is a recycled press release from a think tank…admittedly not a rightwing one, but it’s not based on the kind of research you might find in a journal.

Stopping gas dictating UK energy price could cut bills by £200, thinktank says

Iran war has increased gas price, with effects on UK energy bills that could be avoided, Common Wealth says

The Guardian

People quoted are the director of the think tank, Common Wealth and the guy who wrote the report, Donal Brown, but they’ve not even explicitly said it’s his report.

It’s a lovely idea, the decoupling, but I spent four years of my career working with energy economists, so I was curious who this Donal Brown was:

He’s appears to know a lot about retrofit and science and technology policy, but energy economics:

He’s done a 3 day course.

Discovery

I think it’s useful for the conversation to be publicly aired about the decoupling of electricity from gas prices.

But I think we also all watched the #Tories spend 14 years making policy on the back of think tank lobbying, rather than proper research. #Labour must not fall into this trap and think there are easy wins without unintended consequences.

@JugglingWithEggs Their history doesn't bode well for this; "easy wins without unintended consequences" is a pretty good description of PFI!
@JugglingWithEggs NARRATOR: "Unfortunately, Labour are running headlong at the trap while loudly proclaiming the benefits of the trap"

@JugglingWithEggs There is a similar situation with the few district central heating thermal plants in Oslo. The price per kWh is also tied to electricity prices.

Which is extremely unfair to those who use the service as the costs of creating this heat are pretty much static.

@the_wub

I think the situation with district heating is even more dire, because no one is explaining that these are monopolies.

Residents in properties supplied by a heat network cannot switch suppliers to find better value, which is a key difference from the gas and electricity market.

@JugglingWithEggs Exactly!

The heat energy is not traded on any markets either as in the case with electricity.

@JugglingWithEggs Yep. If electricity were cheaper, the country would end up using more electricity -- which would require more gas at exactly the time that there is a gas shortage. The high price helps to keep demand for electricity aligned with supply of gas.

The reason why gas prices dictate electricity prices is because we're dependent on gas for electricity. It's just a straightforward case of building more solar and wind generation instead.

@JugglingWithEggs my view is that if you want to "decouple" gas price from electric price, you should do it via marginal cost, similar to how marginal tax rates work. The more electricity you use, the higher the cost per unit of each additional unit. The first X units you use cost an amount proportional to the cheapest generation cost, the second X units proportional to 2nd cheapest generator, and so on. I accept it would be complex to calculate, not very transparent, and nobody would like it...
@JugglingWithEggs the easier alternative, which is what Octopus do, is tariffs that vary every half hour and are tied to current supply and demand.

@vksxypants

Gas is required some if the time to meet our electricity needs - but nothing like what it was 25 years ago. Based on 2024 figures, 58% of our electricity comes from renewables already:

Clean power targets

By 2030, the government aims to meet Britain’s electricity demand with energy from clean sources. 64% of British electricity currently comes from clean sources.
