How do I get a smart meter when I have a 3 phase supply?

I have 3 phase electricity with a dual rate meter. I would like a smart meter. I have asked my electrician and he says that it is very easy however the OVO technician who came to fit a smart meter said he couldn't do it. So I am paying over the odds for my electricity because OVO will not put me onto a single phase and install a smart meter

Do OVO offer 3 phase smart meters?

 

3 phase (aka polyphase) installations in domestic properties are few and far between, so it's a minority of meter engineers across the country that have the skills required to complete these installations. There are also some technical challenges in making sure your job is allocated to an engineer with these skills but we are just as keen as you are to have Smart available for these sites ASAP.


If you have a three phase supply we’d would encourage you to book a smart meter appointment as normal online or over the phone on 0330 303 5063. 


This will then go through to a specialist team who will validate that it is single rate job and that an 3 phase engineer is available in your region. If this is the case, they will re-book your appointment with the right engineer. (So please bear in mind your appointment date/time will likely change, but we'll try to keep it the same where possible.)


Unfortunately, if you have a 2-rate meter or are not in an area covered by our current crop of 3 phase skilled engineers, you will need to continue with your heritage meter. We know this will be frustrating, so we are sorry about that, we are working to expand our coverage and by you flagging your interest to us, you are helping us shape where and when that coverage develops. - thank you!

 

 

OVO member but not got a smart meter yet? - Book today!

Thanks folks :grinning: . Does this mean that OVO can fit an S2 model smart meter for my three-phase set up? Or someone else?

It means that they can’t yet do so, @Uncle K.

@Tim_OVO  seems to be re-quoting an answer from a technical source within OVO. They are still evaluating the technology required to run 3-phase SMETS2 Smart Meters on their new Billing System.

It is the Billing Software which sends the SMETS_Read commands to the customer sites and receives the responses. It must then calculate the payment due based on the net import/export figures (what we’re calling “vector sum metering”). Simply adding together the totals for each phase doesn’t work!

If you have a look at this other Topic, it announces that a rival Energy Supplier has installed a 3-phase Smart Meter. That doesn’t mean that it was successful of course. It has to be integrated into the Billing system in such a way that the customer could still choose to switch to another Supplier in future. There’s a lot more to this than simply installing the meter.

Yep my advice is to get that solar installed and stick with your 3-phase non smart meter. 

 

If in the coming months we or another supplier is able to provide a smart meter to accommodate this 3-phase supply, then you’re able to choose to get this fitted and you will be able to measure your exact export. Until then, your Feed in tariff (FIT) will use an estimated method using the readings from your generation meter.

Thanks @Tim_OVO . Although we indeed have a three phase supply to our house, only two of the phases are connected. We have three old-style meters as one of the phases also has a low tariff meter for a few storage heaters (which we don’t use). So we don't have "your 3-phase non smart meter" - and I thought the Feed in tariff scheme was closed to new applications? That was the basis of my original question about two single phase meters - which doesn't seem to be possible.
I understand I have to wait until the three-phase smart meter becomes available but the conundrum is what to do in the interim - not only are we fitting solar panels but also remodelling and need to move the meters anyway - I was hoping to put new meter(s) in the new location rather than two steps of moving existing meters and then replace them with a new meter.
Nothing is simple!
But your help continues to be appreciated.
Cheers

I thought the Feed in tariff scheme was closed to new applications? 

 

 

Closure of the Feed-in Tariff scheme  

      

On 18 December 2018, the government announced their decision to close the FIT scheme to new applicants from 1 April 2019. No new applications made to the FIT scheme from 1 April 2019 will be accredited, subject to some limited exceptions. For more information, please visit the Ofgem website.

 

I’m not sure where this leaves us, @Uncle K. I’ve come to the conclusion that some of our volunteers know a lot more about a lot of things then me. So I’m hoping that we can get you some advice on two things:

 

  1. What solar panel options you have out there to export generation back to the grid (we might move this answer into a new topic to help others). @Transparent ?
  2. What options you have for meter exchanges, meter work, to ensure compatibility your 12kW of solar. @PeterR1947 ?

My solar panels are currently directed to off-grid storage @Tim_OVO so I’m not the right person to ask.

Check with your team running the Sonnen Home Battery Storage in Lincoln area. There’s still an obligation for the Panels to be installed by an MCS Accredited company because OVO requires the Renewable Obligation Certificate in order to balance the tariff being applied.

Someone else will know more about this than I do. Feel free to correct what I’ve just written.

Do you actually have 12kW of PV Panels@PeterR1947 ?

Or did I misunderstand what @Tim_OVO wrote above?

@Transparent  I wish!

 

2.82kW here, that was all I could afford in 2011 but still my best ever investment!

This is the predicament @Uncle K finds himself in:

 

 Although we indeed have a three phase supply to our house, only two of the phases are connected.

If we can’t find any community support, I’ll be digging around internally next week on your behalf, @Uncle K - it’s a tricky one for sure this! 

 

Do we have any meter engineers in this community? I’d very much like to meet you if you are/were…. these situations are likely to be a simple and enjoyable puzzle for you. For me, it’s a lot more tricky…..
