Smart Meter time of use tariffs? Is this possible?

Hello.

I have an Aclara SGM1411-B. I would like to make use of one of the time of use plans so that I am charged less for electricity usage during off peak times.

 

Customer support says my smart meter can’t do that, but from what I have read the Aclara is able to support time of use tariffs and can also be remotely updated to do that.

 

So why am I being asked to pay (£100) for an engineer visit? Can the meter not be updated remotely?

Economy 7 tariffs only benefit people who use a large amount of power at night - generally when they are using night time storage heaters / water heating. Without high night time usage, economy 7 can be very expensive compared to a standard plan. You can find out more about economy 7 here 👇

 

 

If charging an electric vehicle at night, this may not use enough to mean economy 7 is needed. You’ll be much better off using our Charge Anytime plan:

 

 

 

OVO doesn’t currently do Time of Use tariffs other than Economy 7/Economy 10. What did you want to use that tariff type for @uniquerex ?

As it stands, your current meter suggests that you might not have a valid use case for E7 anyway - the cost during daytime hours are significantly more expensive than Standard Variable. It’s not worth it unless you have a use case.

Not that it helps in this case but my Aclara SGM1411-B definitely has at least 2 registers (labelled TOU1 and TOU2) alongside export and such … just looked to double check

Actually, ALL Smart Meters support multiple usage registers, including the Aclara SGM1411-B.

It’s only the Fifth Terminal that this particular model doesn’t support - which you wouldn’t need for your use case anyway.

OK, thanks for putting me straight. I did say ‘may’ ...
