Soaring gas prices consigned a string of energy suppliers to the graveyard in 2021 and could lead to runaway household bills next year as the sector continues to struggle.
The business secretary and energy companies agreed on Monday (December 27) for the need to “ensure UK customers are protected” when they met to discuss how to deal with the energy crisis.
The meeting with Kwasi Kwarteng came after Labour and a boss of a major energy provider called on the government to step in over fears of the rising cost of household bills in the new year.
At the beginning of 2021, energy suppliers were paying 54p per therm of gas but by September that had reached more than £3 and peaked even further to £4.50 just before Christmas.
It was an unprecedented spike caused by something of a perfect storm on global markets.
Last winter was unusually cold in the northern hemisphere. Gas is still a key fuel in heating homes and businesses in much of the world, so the cold temperatures led to a spike in demand, and countries started eating into their gas reserves.
These reserves could have been topped up over the summer, but an unusually windless summer meant wind turbines produced less electricity so gas power plants had to burn more than normal.
Meanwhile, there was less new supply coming onto the market and demand from China was higher than expected; it meant that gas was in short supply and as a result prices spiked.
For energy suppliers in the UK, it spelled disaster. Since 2019 they have been limited in what they can charge customers because of regulator Ofgem’s price cap.
The cap takes into account the price of energy, but does not change often enough to keep up with this year’s steep rises. The cap is moved twice a year.
So when gas prices went up energy suppliers were soon put in a difficult situation where it cost them more to buy gas than they were allowed to sell it for.
Since early September dozens of suppliers have collapsed, with experts predicting further failures. The episode has exposed several flaws in how the market works, and will likely lead to permanent changes.
Many energy suppliers should probably have insured themselves against price rises.
It is a practice known as hedging. An energy supplier will order all the gas and electricity it thinks its customers will need in the months or years ahead.
That way if prices spike, suppliers do not feel the pain, at least not until their hedging period is over, by which time the price cap should have caught up with costs.
And it will catch up in April when Ofgem next changes the cap. Predictions of where the price cap will be set have differed, but the most dire forecast came from investment bank Investec.
Its experts estimate that prices could go from £1,277 per year today for an average household, to £1,995 – a rise of 56%.
Analysts at energy consultancy Cornwall Insight are slightly more positive about April’s cap, saying that it will reach £1,865.
But when the price cap changes again in October 2022 it could go as high as £2,240, according to the consultancy’s models.
While adding that this prediction was very uncertain, senior consultant Dr Craig Lowrey said: “With the energy supply sector still dealing with the exit of more than two dozen companies in a matter of weeks, the need to ensure resilience across the entire market is evident.
“Furthermore, it is not solely domestic customers that are dealing with these new highs in energy costs, as businesses will face their own set of challenges without the protection afforded by the default tariff price cap.”
While price rises may only be temporary – how long they stay that high will depend on global gas markets – the impact of the gas crisis will be much longer lasting.
Firstly, the competitive marketplace with dozens of energy suppliers has been changed beyond recognition.
Bulb Energy, whose rapid growth was impressive enough to warrant a visit from the Prime Minister just this summer, is now in special administration.
Another two dozen suppliers have also exited the market, and more are expected to follow them.
Secondly, the crisis will likely change forever the way that the price cap is calculated.
Ofgem is consulting on a series of proposals which would mark the cap’s biggest overhaul since it was introduced in 2019.
