The vast majority of UK electrical energy now comes from low-carbon sources, but family power costs are nonetheless rising as they’re nonetheless closely affected by world fuel costs.
That is because of the construction of the UK’s electrical energy market, the place wholesale costs are normally set by the most costly generator, sometimes gas-fired energy.
Now a brand new proposal, referred to as “Pot Zero”, is gaining consideration amongst UK politicians as one potential strategy to handle this.
Why low-carbon electrical energy hasn’t lowered payments
Regardless of falling prices for wind and photo voltaic, UK electrical energy costs stay intently tied to fuel markets.
That’s as a result of older wind, photo voltaic, and nuclear energy nonetheless feed right into a market the place costs are primarily based on the most costly supply – normally fuel. Because of this, even low cost power is bought at inflated market charges throughout fuel value spikes.
Supporters of reform, together with the UK Vitality Analysis Centre (UKERC) argue this creates a elementary mismatch: shoppers usually pay gas-influenced costs even when a lot of their electrical energy comes from cheaper renewables.
Prof Rob Gross, Director of UKERC, mentioned: “We’re notably uncovered to fuel costs… That’s the principal driver of our [electricity] costs.”

Defenders of the present system, comparable to Vitality UK and the business physique RenewableUK, level to the robust funding monitor report underneath the present Contracts for Distinction (CfD) mannequin. For example, RenewableUK’s CEO Dan McGrail not too long ago famous that “the business is able to work with authorities to attain [renewables targets]…whereas constructing on returning investor confidence.”
They and others emphasise that any retrospective adjustments might unsettle traders and create coverage uncertainty.
What’s ‘Pot Zero’ and the way wouldn’t it work?
The “Pot Zero” proposal was developed by the UK Vitality Analysis Centre (UKERC). It suggests shifting older low-carbon turbines – notably these on Renewables Obligation Contracts – onto government-backed Contracts for Distinction (CfDs), which pay a hard and fast value for electrical energy.
Any distinction between the fastened value and the market value is returned to or paid by suppliers, and in the end mirrored in shopper payments.
Supporters say this might cut back publicity to unstable fossil gasoline costs, with potential family financial savings of as much as £200 per 12 months if extensively adopted.
Former Vitality Secretary Ed Davey has publicly backed the strategy, saying it might decrease payments with out requiring new authorities spending. “The federal government ought to begin at present… chopping the standard family power invoice by greater than £200,” Davey mentioned earlier this month.
The Division for Vitality Safety and Internet Zero has not formally endorsed Pot Zero, however not too long ago prolonged CfD phrases for brand spanking new initiatives from 15 to twenty years a transfer seen by some analysts as aligning with the strategy in precept.
The place the coverage stands and the political response
To this point, no formal authorities choice has been made on Pot Zero. Nevertheless, discussions about reforming the UK’s electrical energy market have intensified in current months, with a specific deal with making pricing fairer and fewer depending on fuel.
Over 100 Labour MPs not too long ago signed a letter to Vitality Secretary Ed Miliband calling for elementary adjustments to how payments are structured, together with concepts like rising block tariffs and standing cost reform. Some see Pot Zero as a possible a part of this broader shift.
Pot Zero is one among a number of proposals now being mentioned as a part of a wider debate over tips on how to make power payments extra inexpensive and fewer unstable.
Whereas it has gained public backing from some political figures and consultants, it stays one among a number of choices into account, and its future function will seemingly rely on selections made within the subsequent section of market reform.
