Big Bill from NPower.

Hi crk81,

TPR's are assigned to every type of meter. However, they are only really needed on multi register meters as it tells the Supplier, Data Collector and Meter Operator which way round they should bill your readings.

So, yes E7 but also it's needed on any meter with more than 1 dial that has to be read (with the exception of a 1 rate Max Demand meter, but I'll not go into that)

It's also very important because Suppliers that were originally from an old board area (e.g. East Midlands Elec now Powergen) had a system which operated in accordance with the agent for that area (since they were rhe same company prior to privatisation)

Not every region and old Supplier/Agent operated the same way. So, some billed rate 1 as off peak, rate 2 as peak. Some were the opposite way.

TPR allows you to get around this as it defines which register is peak/off peak etc. If you don't use it as a Supplier or Agent, you can transpose the customers readings without even knowing it.

He's a sceanrio I've seen before.

Change of supply 01/04/2006
Peak - 02465
OP - 78924

Latest reading 01/01/2008
OP - 5624
Peak - 87245

Thats the billing from change of supply to now. The bill is huge because the registers have been transposed on the bill. Without checking the TPR, you just don't know whether a) it was set up incorrectly at CoS or b) it was set up correctly and the latest reading has been tarnsposed to create the huge bill.

If a) you would have to replace all bills from CoS. If b) you would just amend the latest bill causing the huge jump.

There are also meters out there which say Peak 1 OP 2 but the Data Collector reverses them prior to sending them on to the Supplier. So, in those cases not even the customer has them the right way around at the meter point (they cause a lot of problems, don't ask!)

Cheers for that info, something i'll keep my eye on when at working dealing with any queries like that.
