The deployment of smart metering in the UK is starting to gain momentum with around 3.5 million Smart Meters already on the walls of Britain’s homes and businesses. As the programme accelerates deployment, some might recall that if all had gone to ‘plan’ we would already have a few Smart Metering Equipment Technical Specifications 2 (SMETS2) meters on the walls. That’s not the case, the SMETS1 rollout is greater than expected, but with the Data Communications Company (DCC) go live finally around the corner it’s time to turn our attention to how to manage the transition to SMETS2.
The reduction in deployment costs that SMETS2 represents might tempt some to go with a “Big Bang” approach to the switch, quickly curtailing their procurement of SMETS1 and replacing them with SMETS2 assets which are up to 50 per cent cheaper, and reduce the exposure of being left holding redundant assets. However, a premature transition to SMETS2 would expose suppliers’ programmes to additional risks. A view potentially shared by BEIS given the low installation target set for the first few months of DCC operations.
Over the past few years we have helped our clients improve their SMETS1 rollout, and many of the lessons are transferrable to the SMETS2 journey, while others, like integration with the DCC will be addressed for the first time. Some of the key challenges include:
This, against a backdrop of SMETS2 being launched near the peak of the rollout, will mean that suppliers will have a much shorter timeframe to learn and improve. This time next year no more SMETS1 will be allowed to be deployed, meaning that the largest suppliers will be deploying thousands of these meters per week while making the transition.
If suppliers are going to be successful they need to use the time between DCC go-live and the end of SMETS1 wisely, balancing the required learning about SMETS2 and the DCC, while still installing enough meters to mitigate the huge installation peaks most of them are facing going into 2018/2019. Continued use of SMETS1 will allow them to strike that balance and allow a measured ramp up of SMETS2, but learning fast will be key.
When will the smets2 be released? it was meant to be early 2017 but that hasnt been the case? will all smets 1 meters be changed to smets 2
Hi Peter,I'm glad you enjoyed the blog.In answer to your question the blocker is a software one at this point. The DCC are still working on their SMETS 2 solution and as such we are not at all clear what the SMETS 1 solution will look like, for example will they use the same system as that for SMETS 2 or build a parallel one for SMETS 1? Without greater clarity it's impossible to know at this point whether the meter firmware will need to be updated - bear in mind that there are many different meters made by different manufacturers with different firmware variants so it could be that the answer is yes for some and no for others, we just don't know yet.So in summary the DCC have a lot of work to do and that’s primarily what will take the time.I hope this helps.Tom
Hi TomEnjoyed your blog on this subject, thanks.You refer to the timing of SMETS 1 meter adoption into the DCC as unlikely to happen until 2018 at the earliest. What is stopping this from happening sooner, do you know? To enable the adoption to take place is this a software/firmware/hardware update, do you know?BestPeter
Hi Constantine, thanks for your message and glad the blog was helpful to you! There are a couple of other considerations that might not have been clear from the blog but might help you understand your energy supplier's actions:1. All suppliers are trying to install meters for their whole customer base by 2020 - this is to meet the government mandate, not doing so will likely result in heavy fines2. The technology to support SMETS 2 meters is only becoming ready now - this will allow you to switch between any two suppliers and for your meter to continue to work as Smart - as such there are very few working SMETS 2 meters in operation in the UK yet and to stand any chance of hitting their government mandate suppliers have had to continue to deploy SMETS 1 meters3. SMETS 1 meters will one day be able to transfer between suppliers - all the current SMETS 1 meters will be "adopted" into the DCC (the system allowing meters to switch between suppliers) - this is unlikely to happen before 2018 at the earliestI hope this is helpful (it may be you know much of this from your research!). It might be a good idea to ask whether your new supplier will be installing a SMETS 2 meter - that way you won't need another meter exchange and will be able to switch supplier without losing your Smart functionality (although only if you switch supplier towards the end of this year as the DCC isn't fully working yet).Tom
Your blog on Smart transition: from SMETs 1 to SMETs 2 is an eye opener to me. I was fitted with smart meters for Gas & Electricity by British Gas in October 2015 and since then (march 2016) I have changed my energy supplier to First Utility. Now First Utility want to fit their own smart meters for our gas and electricity meters. When they made this offer, I asked them why they cannot use the existing smart meters and transfer the readings to their data collecting system but they were unable to give me a satisfactory answer on the phone. After doing a lot of research on the internet on smart meters, I came accross your article which has answered almost all my questions.It appears to me, at present most of the energy suppliers want to experiment with their smart metering system keeping their energy customers in the dark, probably for the benifit of their own pockets. What a waste of, money, time and energy when these people continue to roll out SMETs 1, when it does not achieve the end result of uniformity through out the country where you can change the energy supplier when ever you want to.Now I know what to ask the energy suppliers when they offer to fit smart meters (in my case, change the existing smart meters to one of their own) before giving them the ok.Thanks again for your blog.
