“We’re paying a lot more in energy costs than our European competitors,” said Oliver Harry, head of corporate affairs at Encirc, which makes over a third of the UK’s glass bottles.
Britain has some of the highest energy prices in Europe, driven by its reliance on natural gas and the costs of transitioning to renewables, which are passed on to bills.
The country’s industrial electricity prices were also the steepest in Europe in 2024, according to the latest annual government data.
Standing in the intense heat of the factory’s two huge furnaces, Harry warned, “We’re already seeing an increase in imports into the UK as customers turn to cheap, more unsustainable glass producers,” notably from China and Turkey.
More action needed
Across energy-intensive industries – from steel and chemicals to glass and cement – companies are warning that government support does not go far enough to keep them competitive.
The government said it will increase discounts on electricity network charges to 90% from April, which will save around 500 of the UK’s biggest energy users a cumulative £420 million (US$570 million) per year in electricity bills.
“Lowering bills is central to every decision we make,” a government spokesperson told AFP.
But the steel sector, already weakened by the closure of traditional coal-fired blast furnaces, argues that more action is needed.
“The industry still faces industrial power prices almost 40% higher than in France and Germany,” Gareth Stace, director general of the steel union, UK Steel, told AFP.
The union has called for stronger protections similar to those in France, Italy, Spain and the UAE to shield heavy industry from high wholesale power costs.
Decarbonisation
Electricity is so expensive in the UK largely because more than a quarter of its power still comes from gas, which surged in price after Russia’s 2022 invasion of Ukraine.
While wholesale prices have since fallen, they remain elevated.
Under the liberalised electricity market, the last power station switched on to meet demand sets the price for all generators, and in the UK, that station is usually gas-powered.
“In France, nuclear sets the price fairly often and nuclear is cheaper … so it’s not always the same expensive gas that sets the price,” Sam Frankhauser, professor of economics and climate change policy at Oxford University, told AFP.
In other countries “there are moments in the day where somebody cheaper sets the price and in the UK, those moments don’t exist,” as it is almost always a natural gas plant setting the price, he added.
At Encirc’s Elton factory, where bottles clatter along the conveyor belts to be filled and labelled, executives say energy prices are inseparable from the push to decarbonise.
By the end of the decade, “we’re going to be producing glass bottles that are 80% reduced carbon,” said Harry.
“The UK managed to decarbonise the grid phenomenally because of the exit of coal,” said Gregor Singer, professor at the London School of Economics.
“It’s really unfortunate that this gas price shock came now, exactly at that point where you sort of exited coal but you don’t quite have enough renewables yet.”
“In the medium to long run… it’s almost guaranteed that prices are coming down,” he said.
