I've got a THTC meter setup, can I get lower EV charging rates?

I bought a house in Perthshire a few years ago with THTC installed so have 2 meters. I now have an electric vehicle, but it would appear that I can’t get the low charging rate advertised (and sent by email to me) by OVO to allow overnight charging. At the moment, I have to pay standard rate to charge my car when it would be cheaper to find an on street charger (not easily found in my area). Surely that is not right?

Update on RTS shutdown:

 

As part of the RTS Project development, we are really happy to share with you our progress:

 

As you may be aware, the RTS signal that instructs some of our meters when to move to the “Off Peak Period”  will be closing down soon and we need to arrange for all of our RTS customers to have a meter exchange so they don’t lose any of their meter functionality.

 

The RTS signal will end for our customers on 30 June 2025. The period between 1 July - 30 September 2025 will then be used to close-down the RTS signal and allow us to manage any unexpected customers impacted.

 

After a very successful pilot, from the 17th June 2024 we will begin writing to our Economy 10 RTS customers to invite them to call us to arrange for their meter exchange. 

 

We are continuing to work at pace to enable the same solution for the majority of our other RTS customers and our aim is to begin writing to these customers in Aug 2024. 

 

We will continue to update you on our progress.

Unfortunately, THTC is not currently compatible with Smart Meters - this is being worked on - and Charge Anytime requires a Smart Meter in Half-Hourly Mode, not least to act as a way of verifying that the usage is legitimate.

It’s unfortunate, but that’s just how it is I’m afraid. Until you can migrate, your best bet is to try to charge during the Off-Peak hours.

Connecting an EV Charger to the Off-Peak meter is not allowed I’m afraid if you’re on THTC. You might be able to come off of it provided:

  • You’re NOT in a Load Managed Area - your DNO can help you check this
  • You no longer need THTC e.g. your storage heaters are gone

If both conditions are met, you can make that request to OVO and they’ll try to make the arrangements if possible. It’s not impossible to do if the conditions are right, but it’s mostly down to whether the right engineers are around - and you’ll need an electrician to do some re-wiring as well.

Have a look at Funding Opportunities | Community Energy England which might be appropriate. 

Regrettably I am way up (and out) on the west coast of Scotland...

Might not be applicable but there is the ECO 4 scheme

Good luck with that dream, Tesla batteries are not cheap.

I did wonder about setting up a field of panels with my nearby neighbours and we all reduce our national demand. Could there be any grants to help with that thought?

Actually, the last time I looked the Tesla Powerwall is very competitive considering it has ~14kWh of storage and a 3kW inverter and charger built-in (and built by a company with a proven track record for reliable kit.

You are talking about a micro-grid - as to (government) grants, you’d like to think so given the current political significance around energy.  But I guess this specific subject will sort the wheat from the chaff, politically-speaking - ie political/dishonest shenanigans Vs a genuine interest in reducing our dependance on foreign oil/investment money/foreign ownership/control of our basic resources.
