The Chair
Thank you very much, gentlemen. You are very welcome. I believe that the Minister has indicated that he would like to ask the first questions.
The Parliamentary Under-Secretary of State for Business, Energy and Industrial Strategy (Richard Harrington)
Q
Thank you for coming today, gentlemen, and helping us. As you probably know, the evidence you are giving today is the beginning of the Committee stage of the Bill. May I ask you both to comment on the interop—I cannot pronounce it—on how the Data Communications Company system will help the SMETS 1 meters to be operable throughout the whole system? We keep hearing about it and my shadow and I have discussed it at different times, but I would be very interested in your comments.
Derek Lickorish: I think that interoperability for SMETS 1 meters will come about in two ways. But first, what is interoperability? At the moment, SMETS 1 meters have their own mini data communications company. They have their own communications infrastructure, and it is generally all made by the manufacturer who supplies the meters. There are several of those systems out there. The initial interoperability can come about by making SMETS 1 meters interoperable through their communication systems. That is already available technically, but it requires the participation of the big six to make it happen.
You asked specifically about how the DCC deals with enrolment and adoption—those are the terms used. In the case of Secure Meters, it will take the output from its smart meter service operator system and plug it into the DCC. That, on the current timeline, is due to take place next October. That is based on a whole range of assumptions, and I think it is more likely to come about at some time during 2019, subject to all things here on in going very smoothly for the DCC. So there are two options to make interoperability work.
Richard Wiles: Likewise, at Trilliant, with our meters we offer integration into third-party systems that allow interoperability and for the devices to remain smart. We do that through one of our clients. We also offer a cloud-based smart meter systems operator—SMSO—solution ourselves, and we can provide that interoperability for people who take up our service. That enables them to put meters on the wall pretty quickly, using a similar platform to that of our larger suppliers from the big six energy companies.
We also provide that service through an aggregator that can do secure file transfers that allow even quicker adoptability and the ability to get meters on the wall, but we adhere to the same standards as the DCC for enrolment and adoption as to how we would build that development interface to communicate to our existing infrastructure and make sure that the service requests that come through the DCC path meet the criteria of the DCC, similarly to what happens with SMETS 2.
Derek Lickorish: So SMSO interoperability could be achieved now.
Dr Alan Whitehead (Southampton, Test) (Lab)
Q
Derek Lickorish: We are kidding ourselves if we think that we are about to have a mass roll-out of SMETS 2 meters any time soon. As we heard this morning from the gentleman responsible for DCC, there are 250 SMETS 2 meters connected to DCC, and they are electricity-only; that is 200 more than I thought were connected to DCC. If we were about to have a mass roll-out, we would have at least 200,000 fully interoperable SMETS 2 meters connected to DCC to facilitate end-to-end testing of that system. That is currently not the situation.
The July 2018 date is predicated on the fact that SMETS 2 meters are going to roll out very soon. For that to happen, those meters need to be declared interoperable. Interoperability is essential not only now but in the future. What does that mean for people who do not follow all this stuff at the molecular level? We decided at the outset of the smart meter programme that we would have many world firsts. There are about seven or eight first-in-the-world developments in this programme, one of which is that every meter must be interoperable with other meter manufacturers’ meters so that, should a meter fail, it can be replaced by another meter manufacturer’s meter without the in-home display being replaced. That is a key tenet of the programme.
A process known as smart meter design assurance is supposed to be up and running to prove that SMETS 2 meters are interoperable. That is not up and running, and it has some technical difficulties. Yesterday, a letter arrived to say that one SMETS 2 meter manufacturer has a problem with compatibility of the hub. That is not to say that that will not be solved, but that was only yesterday. Is it just that manufacturer’s SMETS 2 meter or is it all of them? In theory, it should be all of them, because they have all been made to precisely the same specification.
This programme is the first in the world for device-level interoperability, it is the first in the world to separate out the communications system and it is the first in the world to get all the people involved in the SMETS 2 roll-out designing to a 6,000-plus page specification. I hope you can see from that that I do not think we are going to be going very quickly very soon. Having said that, I do not think that the 2020 date should be changed. I believe that the industry should be galvanised into action to solve the problems and then there should be a reflection on what the 2020 date should be. We should not have a date that nobody believes is possible.
Richard Wiles: Trilliant’s view is that there needs to be some coexistence between SMETS 1 and SMETS 2 beyond 14 July next year. Our response to the consultation is that we are concerned that smaller suppliers, which may not have done any SMETS 2 installations to date, may be in a position where they are not first in the supply chain for meters, communications hubs or other parts of the end-to-end system testing. We believe there should be coexistence and that SMETS 1 should run with SMETS 2 until SMETS 2 deployment has been proven at scale and can take over the quantity of SMETS 1 meters that will be deployed.
From our supply chain, we are concerned that if we are forced to turn off our supply manufacturing chain and then we get the go-ahead to recommence production, we will then have to ramp up. For the products that we develop, we have specialist components to ensure that the security is maintained. We need to ensure that other key, core aspects of the supply chain are readily available so that, should the call come to bring SMETS 1 up again at a date beyond 14 July, we can serve and make a credible difference to the actual roll-out and then achieve the 2020 planned deadline.
The Chair
I think you have seen how the sessions are conducted here. Questions come randomly from the members of the Committee as they catch my eye, and may I ask you to speak as clearly as you can for the Hansard Reporters?
I think we will start with the Minister.
Richard Harrington
Q
I will continue from the evidence that I know you heard before, because you were sitting—quite rightly—behind those witnesses. How important do you feel it is that the energy suppliers make a swift and smooth transition to using SMETS 2 meters? I ask that because we have heard from people who have been suppliers of SMETS 1 meters and from others who have taken a broader view, so I would be very interested to hear your view, please.
Dhara Vyas: From the Citizens Advice point of view, we are quite keen to see that transition happen as soon and as rapidly as possible. As I am sure you are aware, SMETS 1 meters do not really provide the same sort of functionality as SMETS 2 meters, and a big part of that is the continuing benefits of SMETS 2 meters. You have heard about the interoperability and the ability to switch, but there is also the kind of loss of functionality in terms of the dynamic currency conversion-enabled services, or DCC-enabled services, that they have access to, and things like “last gasp, first breath”, whereby a network could see if somebody is off supply and act really quickly. SMETS 1 meters do not have that sort of capability built in. So things that really serve to protect consumers are built in to SMETS 2 in a way that they are not with SMETS 1.
Also, there is confusion as the roll-out progresses at a pace and as suppliers and SEGB are working to promote the roll-out and encourage consumers to take up the offer of a smart meter. With different meters going on the wall, consumers are already confused and will ask questions, such as, “My neighbour can do this, and they switched, and they kept their meter. How come I can’t?” So the increased confusion around having more SMETS 1 meters on the wall will cause a problem.
Sacha Deshmukh: I agree that the SMETS 2 roll-out is very important. The only extra contextual point that I would add is that people should remember just what a step forward SMETS 1 meters are from previous meters. So the feedback from consumers who have SMETS 1 meters—several million of them now—is overwhelmingly positive.
I remember a story that was told to me recently. A consumer who had previously been on a prepayment dumb meter had slipped and fallen—she was an elderly lady—and broken her hip, while going out to charge up her key late at night on a petrol forecourt that was wet, in the rain, in a month a little bit like this in weather like this. So a SMETS 1 meter and the capability it offers is a huge step forward for consumers, but I agree that SMETS 2 meters are also incredibly important, for the reasons that Dhara just outlined.
Richard Harrington
No. I will give everybody else a chance. Thank you very much.
Richard Harrington
I am happy to let Mr Morris go first. I know he has been waiting for a long time.
Richard Harrington
Q
Dr Sarah Darby: I am not sure we can yet say that there is a prototype smart grid. The beginnings of smart energy tend to be different in every country and smart metering in this country is different from smart metering anywhere else. In fact, more attention has been paid to the consumer engagement side of smart metering in this country than anywhere else. This is the only country where a fairly intensive effort is put into customer engagement at the time of roll-out of the smart meter, when everyone is offered an in-home display, and all the installers are trained in communication skills to explain what is going on, what can be done with the display, what the smart meter is about and how customers can use it as a tool, if they wish to. This country is a bit special in that way, and we are seeing, on average, modest positive effects.
In the US, where smart metering is widespread, the emphasis has been very much on using it to try to control peak demand, and as an instrument to introduce time-of-use pricing and whack up the prices at peak times to keep peak demand down. They have special problems there, particularly in the hotter states, with air-conditioning in the summertime and very high peak loads, which is an expensive problem for them to manage. The earliest roll-out of smart meters was mostly, in my understanding, to overcome serious problems with fraud.
Dr Richard Fitton: I agree with Sarah, the UK is very strong on smart meters. If you speak to anyone in Europe, a lot of them are envious of the technical standards of the smart meters that are being rolled out. As we have heard from all the sessions, it is a very complicated issue and it is not getting any less complicated, certainly for the consumer.
Our research group’s angle is everything from the consumer side of the meter. We are looking at how to diagnose problems with buildings using the data and systems that are available. We are also developing appliances that will work with smart meters. A big piece of the puzzle that is missing from some of the discussions is the fact that the consumer should be able to engage with the smart meters. As it stands now, they cannot engage with the smart meters. We can log on to the energy supplier’s portal and get a half-hourly reading. But a magic black box called the consumer access device is the gateway to the occupiers having access to their real-time data. This is not a box on the wall that tells them how much energy is costing. It is a consumer access device that streams real-time data to things such as smart appliances and smart heating systems for homes.
That is the whole aim, as far as I can see, of the smart and flexible grid that we constantly talk about. To attach one of these devices is exceptionally difficult and I have never had one successfully connected personally, nor have colleagues or associates. So a big piece of the puzzle is missing in using this data for something that is really smart, rather than just for billing. Billing is clearly important, but the use of the best-value data for the consumer appears to be the missing part of the puzzle. I think that would also push some buttons to help develop the interest in smart meters and get them into people’s homes.
Dr Whitehead
Q
Dr Richard Fitton: I think it is the same with any technology. The greater the penetration geographically across different types of people and property and heating systems, and the greater the spread the better. It is a very difficult question to answer. My thought has always been, when is the roll-out complete; when do we say it is complete? Is it at 90%, or 80%? It may be that 10% of people—I have just made that figure up—will not let you through the door. When is it complete; when do we rubber stamp it?
Dr Sarah Darby: Yes, I think there will always be a section of the population who do not stand to gain very much from having a smart meter; the demand is perhaps very low and there would not seem to them to be a great deal of point. Their impact on the system would also be very small, so I would say yes, we are probably talking in the region of 80%. You would have garnered pretty much all the benefit by then.
