Can a Smart meter provide 2 off-peak time periods for an Economy 10 setup?

I have storage radiators which are powered by two separate off-peak periods. One during the night and a second 2-hour period each afternoon. Would a 5-port Smets2 Smart meter be able to provide 2 charge periods as I now have?

Hey there @Montego77 !

It sounds like you have something like Economy 7, is that right? If so, then I have good news for you and this also applies to Economy 10 too. 5-Terminal SMETS2 Smart Meters can indeed do this, very easily in fact. It’d simply be a case of the storage heaters being hooked up to the 5th Terminal and everything else on the regular terminals, just like you already have now. The meter installer can make sure this is set up correctly - simply make sure to let OVO know when you book the installation appointment and the engineer will make sure to bring the right meter with them. :)

The exact meter that will get installed can vary depending on the supplier and what the engineer has in the van, but the excellent Aclara SGM1412-B is a pretty common choice for these setups and does the job perfectly.

Thanks for your detailed reply. But you have not confirmed for certain that I will still receive 2 separate charge periods each day - one at night and the other in the afternoon. I am at present with EDF and have a 4-tariff meter( 24 hour weekday daytime; evenings; night; + off-peakheating).

No worries, I can try to help with that too.

Thanks for letting me know what tariff you’re currently on, this helps a lot because I now know that you’re on a specialist tariff at the moment. Bear with me as I’ll need to look up some details. I’ll be right back.

Ok, thanks for waiting. I needed to check some details to make sure my theory was correct.

By the sounds of things, you currently have some kind of Complex Meter, which are sometimes known as RTS or DTS Meters if they’re controlled remotely. If you’re happy to show me some photos of your meters, this might help to make sure I’m on the right track.

Unfortunately, these meters are no longer installed by any suppliers and the support for them is being phased out soon - especially because the Radio Teleswitch Service is shutting down. This doesn’t affect any meters where a local timeswitch controls the switching, but it will effectively brick pretty much all meters that are managed remotely via the legacy RTS Service.

Upgrading to a smart meter with Economy 7 will definitely offer off-peak rates, but the exact times can vary depending on where you are. In some parts of the country, you’ll get a single overnight 7 hour block all in one go, while other areas split it up into two smaller blocks. If you’re happy to tell me what county or region you’re in, I can try to look this up. I don’t need to know exactly where you are, just the county is generally close enough.

Just as a heads up, if you do go ahead and switch the meter out, this will also require a tariff change and there’ll be no going back as it’s a one-way upgrade with no downgrade option.

Welcome to the OVO online community, @Montego77  - great first question in relation to the compatibility of smart meters with an Economy 10 set-up.

 

Generally speaking smart meters may be compatible with this dual rate schedule - however it does vary supplier to supplier. At OVO the dual rate smart meters we install offer only an Economy 7 schedule - you can find out the exact peak/off peak times you’d be offered depending on your area here.

Not sure if your set-up is a Radio-Teleswitch (RTS)  meter as @Blastoise186 suspects, but have checked these details with our metering expert who wanted to clarify -

 

RTS Meters ARE still being installed by Suppliers (at VERY low volumes though). SSE is doing so right now and they FULLY support them and will be doing so for as long as required. The RTS Switch off has been pushed back to ensure a suitable Smart solution is implemented but this is still being worked on due to Network challenges outside the control of Suppliers.  The RTS system will not be decommissioned until every customer on it can be moved off.

 

Be interesting to see how this affects your exact set-up...
