Plans to set people’s electricity bills based on where they live have been dropped by the government.
Energy Secretary Ed Miliband said in April the government was considering zonal pricing, but on Thursday it said it would reform the current national pricing system instead.
Zonal pricing supporters say it can lower bills in areas generating more energy, such as Scotland, though some energy firms say it could have scared off investment.
Energy UK, which represents the industry, welcomed the government’s decision while the Conservatives called Miliband’s promise of lower electricity bills “a fantasy”.
The current electricity pricing system means everyone in the country pays the same flat rate at all times regardless of where they live, but critics argue the price is calculated based on the most expensive electricity generated in the country at any given moment.
Greg Jackson, founder and chief executive of Octopus Energy, told the BBC that zonal pricing works in countries such as Australia, Sweden, and Italy and calculates it could “reduce bills by around £100 a year for most households”.
However, energy provider SSE said zonal pricing “would have added risk” to the system, arguing that national pricing creates “a stable and investable environment”.
It welcomed the “much-needed policy clarity” from the government’s announcement, but Kate Mulvany, principal consultant at Cornwall Insight, said “clarity is not the same as resolution”.
“This move will not solve the deep-rooted issues in Great Britain’s electricity market, and it must not be used as an excuse to continue business as usual,” she added.
The decision to stick with a national pricing comes after a three year consultation. In April, Miliband the BBC that pricing reform was “an an incredibly complex question”.
“There are two options, zonal pricing and reformed national pricing,” he said at the time.
“Whatever route we go down my bottom line is bills have got to fall, and they should fall throughout the country.”
