Domestic Gas and Electricity (Tariff Cap) Bill (First sitting)

Debate between James Heappey and Michelle Donelan

Committee Debate: 1st sitting: House of Commons
Tuesday 13th March 2018 Public Bill Committees

[James Heappey]

Q On the last panel, Dermot, the price spike of two weeks ago come up. So, to follow on from Vicky’s questions, first, against your modelling, what event did we see two weeks ago? Was that a once-in-five-years event or a once-in-10-years event, in terms of the price spike it generated? Secondly, how do you model against the reality that there will occasionally be those price spikes, but at the same time that we will all urge you to take as much risk as you are willing to, in order to make the price cap a meaningful cap? It would be interesting to know how you strike that balance between the variability in the wholesale market, albeit that it happens very infrequently, versus our wish that you are as bold as possible with the cap.

Dermot Nolan: Absolutely. Two points on that. First, regarding, the events of last week, it is difficult to be precise. I would say they are more the type of once-in-five-years spikes. I will note that, if I may sound very gnomic, there are spikes and spikes. This was quite an acute spike in the gas price, and then there was a spike in the electricity price, but it was not that long-lived. Forward prices for four or five days did not change dramatically, so it was an abrupt spike but a short one.

The whole point of how to set the cap, and over what time period, is a fundamentally important one. The Bill suggests that the price cap must be updated every six months or less. There is an inherent trade-off. One of the things I particularly want to hear about from consumer bodies is over what period people want their prices to change. All the evidence we have in many ways suggests that people like smooth energy prices. They do not like spikes in their own bill. If the cap is set every six months, and a one-week spike is smoothed out over that six months, there is an appeal to that—you get relatively sure prices over a six-month period.

At the same time, you find that if there have been spikes of whatever form during a six-month period—if there has been, say, a fall in energy prices after two or three months—people say, “Why is this fall in wholesale prices not being reflected in my bill? Why do I have to wait six months for it? Why can I not have it after three months?” If we did a three-month price cap, that would ameliorate that issue, but we might be a little bit more vulnerable to spikes and changes in prices. How we balance that is not straightforward and is one of the things that we would particularly want to hear from consumer groups on during a consultation.

[Michelle Donelan (Chippenham) (Con)]

Q On that point, do you think six months is right? I know you have just described the trade-off between a three-month and a six-month period. Do you believe six months is the correct period? There are people that are concerned about flexibility and fluctuations. In the last panel, we heard that if everybody started buying their energy in advance, it could inadvertently cause a spike. What do you believe?

Dermot Nolan: I think six months is the maximum. If the Bill goes through as is, we will consult on it. I honestly cannot say what we would ultimately pick, because it would be an open consultation. Certainly, I cannot imagine, at this point in the way the energy market is, having prices change every week or month. I think it would be a consultation along the lines that I have already mentioned. There is no perfect number though. We would want to try to hear from consumers what they thought was best and what reflected their preferences.

Q You would say that getting this entire process put through simply will foster competition, and that is one of the goals you believe should be in the Bill.

Dermot Nolan: I think it will have an effect. We have a prepayment meter cap already. I said that switching is only one aspect of competition; I want to be clear on that. After the prepayment cap, we saw that some of the cheaper deals left the market, but not all of them did. Some stayed, including from existing suppliers, and there were still cheaper deals from some of the smaller suppliers. I think that is likely to occur. There might be a measured drop in switching for a period of time, but as long as the mechanisms are put in place, this can facilitate competition over the medium and long term.

[James Heappey]

Q This is similar to the question I asked at the end of the previous session. What does effective competition look like to you as the regulator? Are you looking at measuring this in terms of engagement within the market and net fall in the number of SVT customers? Is it based on some differential between SVTs and introductory or promotional prices? Alternatively, is this an opportunity for transformation? We bring in the price cap, but in the process we look at what has been wrong with our old energy system and what the innovation and disruption is likely to be that leads to something for the future, and whether this is your opportunity to deliver that.

Dermot Nolan: I think it is an opportunity for transformation. I have talked about some of the short to medium-term things we will do. Over the period of the price cap—this would probably be a legislative thing, working with the Department and ultimately with Parliament—it represents a chance to perhaps radically recast the supply market.

The supply market has become quite complex. I am not saying that the system of suppliers acting as vehicles for delivering the various obligations has not worked—in many ways, it has—but we see a situation in which a host of new suppliers will be entering the market in three to five years. These might be quite large ones that do not currently provide energy, and they could come in selling energy in a bundled product with other goods.

We will see electric vehicles being rolled out, and a price cap will have to deal with issues such as electric vehicle charging and how people are charged for them. I see a situation in four to five years’ time in which the energy market could have changed radically. The key point of the price cap is that it has to be flexible to any changes and fulfil its basic role of protecting consumers. With great respect to the suppliers in this room and suppliers already out there, I would hope that we could see radically different sets of people providing energy in five years’ time.
