Time Pattern Regime (TPR) reference sheet

Good morning one and all,

 

Can anyone please direct me to an industry recognised Time Pattern Regime (TPR) Reference Sheet ? I have those issued by Engie but Eon next say that they do not recognise it. This TPR reference sheet shows all SSC’s. I would appreciate any help.  Many thanks

The engie one was updated a year ago, but I don’t think much changed. I’m sure they take their data from the horse’s mouth, so to speak, which now means the Retail Energy Code (REC). The latest TPR reference is included in the Meter Configuration Tables; I think you have to have an REC account to access them. 

If you tell us what you’re looking for, I can probably help. Meanwhile, you may be able to see my Excel files and download them from here.

    Many thanks Firedog. I am still having issues with Eon who installed a new smart meter last year on what we agreed was an SSC0939 basis.  I was told last week that this new smart meter should never have been installed on this basis.  Eon say that they do not recognise Enigie’s TPR’s. From the link you sent me I saw that the lisings for the TPR’s went only to the 600’s. Any thoughts please ?

    Many thanks

    I did put a note in the file to the effect that the TPR listing was truncated; I don’t know why.

    I took the relevant bits from the tables to show what SSC0939 means:

    This is a standard Economy 10 regime with 10 offpeak hours 04:30:0730, 13:00-16:00 and 20:30-00:30. Not many suppliers offer this type of tariff, and billing systems aren’t normally geared to managing them even though a SMETS2 meter should be able to handle them. Do you have it confirmed in writing from E.on Next that your account and meter are set up for Economy 10 with these offpeak hours?
