Dear Forum,

Please does anyone know how to tell which rate is being used - so that I can see what times the Economy 7 changes to Day rate after the clock changeĀ  to BST please?

Thank you

Sharon

Ok, Plan B is probably best here. By the way, if you press either button on the meter, the display will light up. :)

Ā 

Iā€™ve double checked the full 108 page long user manual for this meter -Ā feel free to grab a copy by the way - and I think I know the best way forward for this.

Ā 

You should notice that both ToU Rate 1 and ToU Rate 2 have readings on them which arenā€™t zero. The easiest way to know which one is the day rate is to take a reading from both of them at say, 10am and then come back an hour later and take another reading. Whichever one has increased is the day rate and the other is the night rate.

As for your site, I believe your DNO is Electricity North West with an MPAN Area ID of 16. From that, using the handy lookup table on another threadā€¦

Ā 

Ā 

I deduce that your Economy 7 hours are as follows:

Ā 

Winter

  • Peak: 7am - midnight
  • Off-Peak: midnight to 7am

Ā 

Summer (because of your Aclara smart meter)

  • Peak 8am - 1am
  • Off-Peak: 1am - 8am

Ā 

Iā€™ll askĀ @Jess_OVOĀ to double check my numbers are accurate too. I think Iā€™ve got them right but never hurts to be safe!

Ā 

Ā 

Sounds right to me,Ā @Blastoise186.

Ā 

Hope this helps you manage your peak/off peak usage patterns,Ā @SDHĀ - Have you managed to submit both readings via your online account or OVO app yet? This will really help make sure your energy charges are accurate and up-to date if weā€™re not yet able to communicate with the meter remotely. Thereā€™s more advice on how to go about this over here:
