UK 'set to reject' zonal pricing plan loathed by renewables developers

Energy secretary Ed Miliband promised decision would come on controversial proposal ahead of pivotal renewable energy auction this summer

The UK government is reportedly set to reject a proposal to move to a zonal system for electricity prices that has faced deep opposition from wind and solar power developers.

Government officials have said that they are inclined to drop the proposal, reported Bloomberg, citing unnamed sources that are said to have been briefed on the issue.

The sources cautioned that the final decision has not yet been made and will require involvement from Prime Minister Keir Starmer.

Department for Energy Security and Net Zero (DESNZ) said it was “categorically untrue” to report that energy secretary Ed Miliband was leaning toward rejecting the proposal, reports Bloomberg. “No decision has been made,” the department said. “We will provide an update in due course.”

DESNZ has been consulting on the proposal to radically reform Britain’s power system as part of its Review of Electricity Market Arrangements (REMA).

Miliband has come under pressure to make the decision soon from developers who desperately need certainty over the issue ahead of bidding wind and solar projects into the UK’s upcoming renewable energy auction, AR7.

Miliband told industry body RenewableUK’s Global Offshore Wind summit last week that he would decide ahead of the auction round this summer, amid speculation that he could defer it until after.

RenewableUK and most major renewable energy developers have come out strongly against the proposal, saying it would create huge uncertainty for projects and could ultimately result in higher bids in auction rounds.

A zonal system, as used in many other countries, would see the UK government split the power market in Britain into different geographical zones, with each having different electricity prices based on their respective levels of supply, demand and available grid.

Areas that have high green power supply and low demand, like Scotland, would see generally lower prices, while areas such as the southeast of England would see their prices rise.

The idea is that this would incentivise developers to build green capacity where it is most needed to capitalise on those higher prices.

One high-profile backer of a switch to zonal pricing is British developer Octopus Energy, whose founder Greg Jackson has said that without such a switch power costs in the UK – some of the highest in Europe – will “continue to spiral, guaranteeing industrial decline.”
