No, I will not; I am going to make some progress.
Pursuing the Opposition’s policies would be nothing short of a disaster, not just for consumers but for investment, for decarbonisation and for energy security. If any Government were so misguided as to intervene with the two prices regulations proposed by the right hon. Member for Don Valley (Caroline Flint) it would lead to chaos in our energy system.
Today’s latest debate on energy prices does have something new—well, sort of new. The right hon. Lady—quite rightly, in my view—wants us to focus on the fact that while wholesale prices for gas and electricity have by and large fallen in recent months, most energy companies have yet to cut their retail prices. Many people, over many years, have looked at this phenomenon—at the way in which wholesale and retail energy prices relate to each other and at how there always seems to be a time lag between changes in wholesale prices and in retail prices, especially when wholesale prices are falling. The explanation that energy firms give for this time lag is the way in which they buy their wholesale energy: to spread their risks and hedge, to smooth out the prices they charge customers, they buy much of their gas and electricity six months, 12 months, 18 months or even further ahead on the futures markets. Therefore, energy firms claim, they cannot immediately pass on today’s wholesale price falls, because the gas or electricity they are supplying was bought at the higher prices of months past. The right hon. Lady spoke a lot about that. Like many people before her, she is worried about the so-called rocket and feather problem: the energy companies appear all too ready to allow their retail prices to go up like a rocket when wholesale prices rise, but when wholesale prices fall their retail prices are no longer rockets but feathers, gently falling ever so slowly so that the energy firms can profit.
That argument leads to two questions: first, is it true? Do energy prices follow this rocket and feather model? Secondly, if it is true, what should we do about it? My answers to these questions are clear. It may well be true—there seems to be evidence that it happens. It was one of the reasons I asked the competition authorities
last year to undertake the first-ever annual competition assessment of the energy markets. Interestingly, the independent competition authorities stated:
“We have found that suppliers do not adjust their prices as quickly when costs fall compared to when wholesale costs rise.”
In fact, it was one of a number of reasons and findings that led Ofgem to propose a market investigation reference. That is exactly what I think we should support when faced with such a worrying finding for consumers. There should be a no-holds barred inquiry by independent experts, whom we have given real teeth to act for consumers. That is the action that the right hon. Lady should be proposing and that I am backing as Secretary of State for Energy and Climate Change.
