Watch: how zonal pricing would save everybody’s payments
On this video, we dispel the parable that clients within the South would pay extra – nevertheless it’s additionally maybe one of the best clarification we can provide for zonal pricing. Give it a watch in 5 minutes:
The spark notes
What is going on on?
The federal government is contemplating transferring Britain to zonal electrical energy pricing. Proper now, now we have nationwide pricing, which suggests all vitality producers promote their energy for a similar wholesale value, irrespective of in the event that they’re in Aberdeen or Devon. With zonal pricing, there could be a special wholesale value in every space.
It’d sound like a postcode lottery with winners and losers. It is not: it is about making our entire system extra environment friendly, saving a giant pot of cash to be shared out amongst everybody.
However would the South see payments go up? No.
With zonal pricing, everybody may save.
It is anticipated to save lots of no less than £3.7b a 12 months – £55b by 2050 – and it would be as much as the federal government to decide on tips on how to distribute these financial savings, proportionally to reward areas with extra renewables, or equally throughout everybody. They’ve already dedicated that nobody’s payments would go up with zonal pricing.
What’s so unhealthy about the established order, a nationwide pricing system?
Proper now, the way in which we purchase vitality is massively outdated: a system designed means again when Britain bought its energy from a handful of coal stations. Making use of it to in the present day’s vitality – a various mixture of small and massive mills from low-cost wind generators to costly gasoline stations – results in ludicrous waste that prices you billions.
This is how we purchase vitality now.
Step 1: Britain buys wholesale electrical energy “blind”, with out contemplating whether or not the ability can really get to its customers – and pays dearly for the fallout when it may possibly’t.
For every half-hour of the day, there’s one nationwide electrical energy value set by the most costly producer within the combine. This is a fast visible of the nationwide value being set:
To maintain that single value decrease, we order the most affordable sources we are able to: which means a variety of wind energy from the North and Scotland.
Proper earlier than it’s on account of be generated, we realise we are able to’t get that energy all the way down to the South with out inflicting main visitors jams and blowing up the grid. Which brings us to…
Step 2: balancing. We repair our mistake by paying those self same generators to modify off and paying gasoline stations to modify on at inflated last-minute costs nearer to customers. Yup – we regularly pay thrice for a similar vitality.
This is how The Instances wrote about wasted wind again in March ’25
Ludicrously, we preserve making this error time and again. It is price Britain over £418,000,000 within the first 4 months of 2025 alone.
You foot the invoice, and mills revenue.
How is zonal pricing higher?
With zonal pricing, there’d be one electrical energy value for every ‘zone’ throughout the nation, set by the worth of vitality producers within the space. The wholesale value could be decrease in areas with a number of low-cost technology (within the North and Scotland), and a bit increased in crowded areas with out a lot technology.
We would pay barely increased upfront wholesale prices general, balanced out by even greater general system financial savings as a result of we would not should do the ‘cleanup’ (switching wind generators off and shopping for additional gasoline). Basically, we pay in a single transaction as a substitute of three. Vitality producers’ revenue will get become financial savings on clients’ payments as a substitute.
How would zonal pricing unlock £55 billion financial savings?
We commissioned an impartial guide, FTI, to mannequin what a zonal pricing system with 12 zones would price between 2030-2050. They labored out zonal pricing would save £55 billion general (or round £3.7b a 12 months). Right here’s how:
- Wholesale electrical energy costs go up by £34.7 billion. Total, wholesale prices would go up, as a result of we’d be shopping for extra from mills throughout the nation who’re costlier at face worth. BUT:
- Balancing prices go down by £40.2 billion. That is the ‘tidy-up’ financial savings I discussed above: we do not have to pay to modify generators off, or pay additional gasoline mills to modify on (technically these are referred to as “constraints” prices).
- Sure vitality producer earnings shift to invoice financial savings of £64.5 billion. Proper now, low-cost producers receives a commission the identical as the most costly unit though their energy is affordable to make, and pocket the distinction as revenue (referred to as “inframarginal rents”). Beneath zonal, when producers in a single zone bought to a costlier zone, the grid operator would take the distinction and provides the saving to clients (referred to as “congestion rents”) There’s extra to this: learn it right here.
- Wind turbine subsidies go up by £15 billion. Contracts for Distinction (CfDs) are subsidies constructed into vitality prices to encourage traders to construct wind generators, guaranteeing them a gradual value for his or her vitality, even when the wholesale value is decrease. Now producers aren’t being paid like they’re costly gasoline mills, CfDs would go up a bit to succeed in that agreed value.
How lengthy wouldn’t it take to implement a zonal pricing system?
We predict it’d take 2 to 4 years, however others assume it may very well be achieved in 18 months. Both means, it’s value doing, as a result of the prices of our present system are going up and up. We’d like decisive motion from the federal government as rapidly as potential.
That is the spark notes achieved.
You are now transferring from delicate to ‘Thai spicy’.
Buckle up…
A deep dive into zonal pricing
Watch Greg get into the nuts and bolts:
We’ll get into every level in additional element beneath.
How our nationwide pricing system works (the ‘establishment’)
Nice Britain at the moment makes use of “nationwide pricing” in its wholesale electrical energy market. Nationwide pricing means there is only one electrical energy value masking the entire nation. That is the worth vitality producers receives a commission for his or her energy, whether or not they’re a gasoline energy station in Land’s Finish or a wind turbine in John o’ Groats. This value adjustments each half an hour.
This doesn’t imply clients’ vitality charges are the identical throughout the nation proper now.
Wholesale electrical energy prices solely make up a few third of a typical invoice. The opposite two thirds are made up varied prices like sustaining the grid and transporting the vitality round, a few of which do fluctuate regionally already. So Britain already has a postcode lottery – clients in northern Scotland pay £96 extra per 12 months than Londoners, in north Wales and Merseyside it is £120 extra.
How we purchase energy in our nationwide market
Step 1
We purchase electrical energy on the wholesale market (with out checking that it may possibly really attain its customers)
The wholesale market is like an public sale. All of the vitality producers within the nation line up by value (that is referred to as the “advantage order”). Consumers order as a lot as they want, ranging from the most affordable energy (normally renewables) as much as the most costly. An hour earlier than the vitality is definitely going for use, the public sale closes.
- We pay for ALL the ability on the value of the most costly unit ordered (i.e., normally which means we pay for a great deal of low-cost renewables as if they’re costly gasoline.)
- Producers not ordered within the public sale (the most costly ones) are instructed to not change on.
This is a brilliant fast visible of that in motion:
There’s one thing necessary lacking: we haven’t thought-about the place the producers are in relation to the vitality customers.
Vitality doesn’t simply magically get from one place to a different: it’s bought to journey by way of miles and miles of wires first. And similar to on actual highways, there are elements of the grid that get congested and might’t deal with as a lot energy flowing by way of as we want. (Extra on grid bottlenecks later.)
However that’s most likely nothing to fret about proper?
Mistaken.
Step 2: balancing
We pay a second time to modify these generators off within the balancing market
An hour earlier than the vitality will probably be generated and despatched down the wires, the Nationwide Vitality System Operator (NESO) takes over to ‘steadiness’ it, i.e. verify the ability can really get from A to B to maintain the lights on.
What normally occurs: OH NO, we’ve purchased a great deal of wind energy in Scotland when most of our vitality customers are down South. There’s no means we are able to get the ability there with out blowing up all of the wires. So, what can we do?
We inform the wind generators to modify off, however we nonetheless should pay for the vitality we ordered from them. Bother is, in the event that they don’t generate, they’ll miss out on an additional little bit of revenue (referred to as “Contracts for Distinction”). So they refuse to modify off except we sweeten the deal. We pay up. Typically, they’ll receives a commission extra to not generate than to generate.
We pay all of it. The wind will get wasted.
However now we’ve bought greater issues…
We wanted that vitality for our clients within the South. How can we preserve the lights on?
Step 3: extra balancing
We pay a third time to fireplace up gasoline mills to fill large gaps down South
Bear in mind the gasoline mills we instructed to not generate again within the wholesale market as a result of they had been too costly? Time to go crawling again. They’re nearer to clients they usually can hearth up in a rush however they cost an inflated value as a result of we requested so late.
We find yourself shopping for an enormous portion of our vitality wants this fashion, and it is solely rising:
Supply: Nationwide Vitality System Operator, 2024. Scheduling and Dispatch Choices webinar
Within the first 4 months of 2025, Britain has spent £418,000,000 on final minute adjustments within the balancing market: £68 million telling wind farms to show off and £326 million on firing up gasoline crops.
It’s ludicrously wasteful.
Zonal pricing helps repair it. We clarify all this in additional element later.
Why is our system so very damaged?
- Our vitality is altering, however our markets haven’t caught up
The nationwide market was designed earlier than the primary iPod, again when Shaggy was topping the charts. Since then, renewables have gone from 7% of the nation’s energy supply to 46% and we’ve banished coal altogether. Not like coal, we are able to’t management when renewables generate – which suggests we have to handle them completely otherwise. The ‘front-end’ of the system has reworked, the again finish is lagging behind.
- Fuel units the worth of renewables 97% of the time – and producers revenue
As we defined earlier, with a single nationwide value, wind and photo voltaic farms sometimes receives a commission no matter the most costly energy plant within the combine is paid, and pocket the distinction as earnings. These earnings are technically referred to as “inframarginal rents”.
What’s good about that is that these producing the most affordable energy get rewarded probably the most, encouraging extra funding in renewable vitality.
The thought with retaining nationwide pricing is constructed round retaining earnings for renewable producers as excessive as potential.
A wind farm close to Inverness will come on and generate low-cost, carbon-free energy. Will probably be paid the identical as a gasoline plant close to Shoreham on the English Channel. Traders will see how a lot revenue renewable vitality makes and make investments extra in them. Finally, this may lower payments by knocking costly, unstable, typically imported fossil fuels out of the combo of vitality sources.
This sounds nice in concept, in actual life it isn’t going so easily.
And critically, clients are lacking out on the rewards of getting all this homegrown low-carbon energy.
- Numerous wind technology is constructed removed from clients, behind grid ‘visitors jams’
It is tremendous necessary to steadiness provide and demand on the ability system precisely always. Consider the ability system because the water pipes in your house. If there’s an excessive amount of water, the pipes are going to blow. If there isn’t sufficient water, good luck having a shower! So let’s assume we’ve bought the correct quantity of water, now what concerning the pipes?
Getting electrical energy from the generator to the client requires wires. If there will not be sufficient wires or capability to move the electrical energy from a wind farm to the place it’s wanted, you might have a grid bottleneck. That is alternatively generally known as grid ‘congestion’. If there’s an excessive amount of electrical energy making an attempt to undergo that bottleneck, some must be switched off or “constrained”. In any other case, the wires will overheat and issues begin going bang.
One of many different large issues we at the moment face is that the majority of our ‘water’ is in a single place, while most of our ‘showers’ are in one other, and the pipes merely aren’t large enough to get the correct quantity of water from A to B on the proper time.
- There’s no incentive to construct wind generators the place they’d be actually helpful
As a result of our nationwide wholesale market buys energy with out contemplating the place it’s, wind mills revenue even when their energy by no means will get to customers. It’s of their finest curiosity to construct the place it’s windiest — typically behind bottlenecks in distant areas.
Why would you construct a wind farm someplace it’ll simply be switched off? As a result of the present guidelines imply you’ll nonetheless receives a commission for being switched off.
This implies we now have very bizarre issues happening within the system. Some large Scottish wind farms inbuilt the previous couple of years (and subsidised by invoice payers) solely generate round a 3rd of the time they need to be — but nonetheless receives a commission for the opposite two-thirds they don’t produce. Scotland’s largest offshore turbine bought paid £65 million to modify off final 12 months.
A few of these wind farms even compete with one another to get turned off first.
We predict it is excessive time we rebalanced this method again in favour of shoppers.
What do we have to repair?
For a giant system improve from fossil fuels to principally renewables, we want new, higher guidelines to ensure issues are working correctly and in one of the best curiosity of the invoice payer. We’ve three large arguments.
- We have to cease constructing generators behind grid bottlenecks. Traders are principally constructing ‘money-making machines’ that make their revenue by being paid to change off more often than not, as a substitute of being paid to energy Britain. It’s incorrect and unfair for individuals and companies. We’ve to alter the principles.
- We have to construct new pylons and wires neatly. Upgrading energy strains will assist repair grid bottlenecks, however they’re eye-wateringly costly. Since bill-payers foot the prices, we have to be as environment friendly in constructing the grid as potential by utilizing extra vitality regionally.
- We have to get the cheapness of renewable vitality onto clients’ payments now, not in ten or fifteen years’ time. We’ve a few of the highest electrical energy payments on the planet – principally on account of the price of gasoline – and we have to lower the price of residing. Clients need to see the good thing about welcoming renewable technology. We’d like a greater steadiness between generator earnings and buyer invoice financial savings.
This is how zonal pricing helps repair our damaged market.
How we’d purchase energy in a zonal market
Step 1: the wholesale market
We order electrical energy regionally in smaller wholesale markets
To purchase energy, we’d nonetheless line all of the producers up by value and order from most cost-effective to most costly. This time, as a substitute of 1 nationwide public sale, there’d be one for each zone. Every zone buys its electrical energy from its personal producers.
There’d be a single value in every zone, primarily based on the worth of the most costly unit.
That value could be decrease in some areas, and better in others – however even in areas with a better wholesale price, clients would see their payments go down.
Step 2: balancing
We use the balancing marketplace for small tweaks solely, saving billions
We wouldn’t spend tens of millions day-after-day correcting errors made within the wholesale market, switching wind generators off and shopping for final minute gasoline. Prices would drop considerably as a result of we’re paying for electrical energy as soon as as a substitute of thrice.
How do vitality prices change general with zonal pricing?
We commissioned an impartial guide, FTI, to mannequin what a zonal pricing system, with 12 zones, would price between 2030-2050. Their findings?
Zonal pricing results in no less than £3.7 billion in price financial savings per 12 months from 2030 to 2050 – a complete of no less than £55 billion – in comparison with what we’re on observe for.
It does this by tidying up the system that creates the ultimate value, which includes some prices going up however others happening sufficient to supply an general internet saving for all by way of a way more environment friendly system. Let’s break it down.
1. Constraint prices go down by £40.2 billion.
×
“Constraint prices” are what the grid pays to show completely good wind farms off and overpay gasoline crops to activate. These constraint prices have risen sharply: in 2017, they price £170 million. This 12 months, they’re on observe to hit £1.8 billion.
With out reform, by 2030, they’ll no less than double and even quadruple that as much as £7.8 billion per 12 months, relying on how rapidly we construct extra infrastructure.
Beneath zonal pricing, constraint prices nearly disappear altogether. Mills are solely paid for energy they will bodily ship, absolutely accounting for grid bottlenecks. We pay for what we use, not what we may use.
2. “Inframarginal rents” go down, producing £64.5 billion in helpful “congestion rents”.
×
Translation: a few of the earnings at the moment paid to mills flip into invoice financial savings as a substitute. Greg explains this in below a minute right here.
Zonal pricing means we strike a greater steadiness between generator earnings and clients’ want for decrease payments by turning some inframarginal rents into “congestion rents”.
Zonal wholesale markets imply these zones with a number of low-cost, renewable vitality can pay renewable costs extra typically (as a substitute of getting their value set by gasoline) and see the monetary profit mirrored straight on their vitality payments.
So how do ‘congestion rents’ work? If a wind farm has extra energy than locals within the zone want, it may possibly ship its energy to a different zone in want of cheaper electrical energy. To maintain issues honest, mills in Zone A will solely ever promote energy at Zone A costs, while shoppers in Zone B can solely ever purchase energy at Zone B costs, no matter the place that energy is coming from or going to.
When the grid is working effectively, every zone must be just about the identical value. Nonetheless, when the grid turns into overworked, two issues occur:
- Zone A goals to dump its extra low-cost renewable energy regionally.
- Zone B is prepared to pay a bit additional to make up their native shortfall.
On this state of affairs, Zone A costs at the moment are decrease than Zone B costs and begins to ship over a few of their low-cost energy to assist out.
Some sharp-eyed readers would possibly ask what occurs to the lacking cash – a few of Zone A’s energy is being bought on the lower cost, while being purchased by shoppers in Zone B on the increased value. Beneath nationwide pricing, this lacking cash would go to the mills in Zone A as revenue. Beneath zonal pricing, this cash goes as a substitute to grid operators, straight decreasing the system prices already in your invoice used to fund grid upgrades, upkeep, and different tremendous necessary issues.
This transfers £64.5 billion value of generator earnings (“ inframarginal rents”) to shoppers within the type of ‘congestion rents’.
3. Wholesale electrical energy costs go up by £34.7 billion.
×
“Wholesale electrical energy costs” would go up, as a result of we’d be shopping for extra energy near customers within the wholesale market – however the enhance is outweighed by financial savings in system prices.
Proper now, we normally find yourself shopping for that energy anyway at an inflated value proper earlier than we want it: below zonal, we’re simply transferring that buy into the wholesale market as a substitute of the balancing market, decreasing the price.
Wholesale costs can even fluctuate relying on the place you reside within the nation below zonal: however that is utterly by design. So:
What would occur to wholesale prices in every zone?
In zones with a number of renewables (widespread in North England and Scotland), most of their vitality must be low-cost clear sources, so the ‘most costly’ unit must be a lot cheaper. Outcome: individuals in North Scotland gained’t have the worth of their clear native energy set by a gasoline generator in John O’Groats. This energy might be bought quite a bit cheaper a lot of the time, straight benefitting native shoppers and companies, serving to to ship financial development to those areas.
In crowded areas with fewer mills (extra widespread within the South), they’ll have much less native renewables in order that they’ll have to purchase extra from gasoline mills. Their wholesale value could also be increased than it’s now. Nonetheless – and right here’s the tremendous necessary half – at the moment we’re paying for these gasoline crops to activate anyway, simply not within the wholesale market – so the prices switch from one space to a different, and these clients can nonetheless save general due to the assorted system price financial savings.
It seems cheaper for a lot of causes:
- Wholesale markets are far more aggressive than the balancing market, so we regularly get the electrical energy for a lower cost.
- We spend much less cash compensating mills for turning off (and never paying them to activate within the first place).
- Versatile property, akin to batteries and interconnectors (the cables that hyperlink us to different international locations) run extra effectively – working with the system, relatively than towards it. We drill down extra into interconnectors and batteries right here.
It is also good for the South as a result of there’ll be a giant incentive for corporations to construct renewable vitality in these zones as a result of they’d be capable of promote their energy for a better value there (and as they constructed extra, it might push the wholesale costs, and subsequently payments, down over time!)
To sum up: zonal helps us purchase the most affordable deliverable energy while unlocking different efficiencies by way of aggressive native wholesale markets, as a substitute of hiding these prices elsewhere in your invoice, leading to £34.7 billion additional in wholesale prices by 2050.
4. Contracts for Distinction go up by £15 billion.
×
Contracts for Distinction (or CfDs) are Authorities contracts designed to assist fund renewable initiatives. They primarily assure the generator that they’ll be paid a sure value for his or her energy it doesn’t matter what the wholesale electrical energy value is. If the wholesale electrical energy value goes above this fastened value, the generator pays the distinction again to invoice payers. If the wholesale value goes beneath, the generator will get a prime up.
Contracts for Distinction are used everywhere in the world as a option to encourage funding in new renewable technology by offering extra secure long-term revenues.
Boiling it down: as CfD’s prime up (or down) the wholesale value to a specified fastened value, the extent of funds solely depend upon the underlying wholesale value. Let’s say a Scottish wind farm’s fastened CfD asking value (or ‘strike value’) is £70, and the common nationwide wholesale value is £50. This implies the common prime up this wind farm receives is £20.
The explanation CfD funds go up below a zonal pricing system is easy: most of our wind farms are situated in the identical place – within the north – and below zonal pricing, wholesale costs are on common a lot decrease within the north.
So returning to our Scottish wind farm asking for a hard and fast value of £70. Beneath zonal pricing, its common native wholesale value has dropped to £30, which means the common CfD top-up will increase to £40. In the end these wind farms get precisely the identical value for his or her delivered energy (£70), so it doesn’t price us any additional, it is simply break up otherwise between totally different elements of the market.
To recap: 2+2 equals the identical as 1+3. In locations the place wholesale prices go down, CfD prices go up by £15 billion by 2050, however the general price of helpful wind energy stays the identical.
Extra data on financial savings with grid interconnectors and batteries
×
With zonal pricing, versatile or ‘two-way’ property (issues that may eat or provide electrical energy at totally different occasions) like interconnectors and batteries reply to efficient native wholesale costs that absolutely take into account grid bottlenecks and replicate the realities of native provide and demand, relatively than blunt nationwide costs that incessantly inform them to do the incorrect factor – assume ‘sq. peg, spherical gap’.
Each of those are incessantly paid to stream the ‘incorrect means’ by the present system.
Batteries
Britain’s principal grid bottlenecks are within the north. Batteries, in concept, are completely positioned to assist with this downside, charging when there’s an excessive amount of energy and discharging when there’s not sufficient – however this doesn’t fairly occur below nationwide pricing.
As much as two-thirds of paid last-minute tweaks by batteries within the north, supposed to assist repair grid bottlenecks, as a substitute merely undo unhealthy directions they already acted on from the wholesale market. The one nationwide value merely doesn’t comprise sufficient data to get them working correctly within the first place. Garbage in = garbage out.
Interconnectors
It’s an identical story with interconnectors (the cables that hyperlink us to different international locations). Interconnectors are tremendous difficult, primarily as a result of they join two utterly totally different international locations and energy techniques, which means something we tweak on our finish must be agreed with the related nation too. However on the easiest stage, they stream energy from a rustic or space with a lower cost to 1 with a better value.
By 2030, these interconnectors may stream the ‘incorrect means’ as much as one-third of the time, importing energy into the north once we want it least, while exporting energy from the south once we want it most, driving up our electrical energy payments as a substitute of constructing them cheaper. At these occasions, zonal pricing would make native energy costs replicate native wants, which means these interconnectors would solely import or export when and the place they really must.

How would zonal pricing have an effect on clients’ payments?
Zonal pricing makes the system far more environment friendly, which unlocks a big pot of cash. The federal government then will get to determine tips on how to particularly allocate the financial savings.
They might select to offer areas with extra renewables further financial savings as reward, or may share the profit equally between everybody:
There’s greater than sufficient to make sure everybody saves, and the authorities have dedicated that each one areas would save with zonal pricing.
We have made a video digging into why the South could be no worse off with zonal pricing right here:
How would the federal government implement zonal pricing?
We predict this entire reform might be achieved in two to 4 years. Others have mentioned we may go quicker: Arup – a revered skilled financial consultancy agency – mentioned it may very well be achieved and dusted in 18 months. It may actually be achieved by 2030.
The necessary factor now’s the federal government decides so everybody is aware of what the principles of the sport are, which is unimaginable to know proper now. Zonal pricing is the one possibility on the desk it has correctly explored, and the one one with strong, system-wide evaluation that has had all its workings revealed to be scrutinised by anybody who desires to.
Quite than extra delay, it’s time to get on with implementation and determining how finest to unfold the financial savings throughout invoice payers within the fairest means potential.
If the federal government decides now, it may possibly have a really profitable renewable public sale spherical this 12 months as a result of it has already promised outdated guidelines will nonetheless apply one final time (referred to as ‘grandfathering’). This implies a number of mills will attempt to get their initiatives into the spherical which favours mills way over invoice payers to make more cash.
However the general system financial savings from transferring to zonal pricing are sure and mandatory. The federal government has mentioned one thing wants to alter – issues are getting too costly the way in which it’s. If we don’t get on with actual reform now, we will probably be turning to the emergency brakes – general worse for mills and invoice payers – in a couple of years.
Conclusion
Our single nationwide zone made sense as soon as once we had a couple of large coal energy crops once we cranked the coal energy crops up and down twice a day, however the vitality system is changing into extra advanced to satisfy the wants of contemporary Britain with extra renewable vitality.
We’d like a system that enables the cheapness of renewable vitality to lastly be pulled by way of to invoice payers, relatively than persevering with to vow it can in ten years’ time. Extra importantly, with out correct locational indicators in our system’s guidelines, we’ll construct our system in a extra inefficient means, making it costlier than it may very well be.
Zonal pricing is the one possibility on the desk for the reform we want proper now. Reform is tough work, vitality payments will preserve rising.
