The electricity EAC appears to be the responsibilty of the Data Collector used by the energy supplier as per earlier post if you follow the elexon link referenced within it.

It seems there is some correlation to my rolling year consumption figure, but with some other tweaks thrown in - like why is Sep up on august?

My guess was way out then. Your EAC is in the ball park.

Thank you - I think! 🤕

That document is incredibly difficult to understand and would tax even the most nerdy amongst us. It also describes the data uses at all levels in the supply system but doesn't concentrate on individual consumers or meter point - and so while it's probably vital in industry terms, it's absolutely useless for virtually all consumers.

Reading elsewhere suggests that frequent / regular meter readings help keep the final EAC as accurate as possible, that data errors do occur but are difficult/impossible to correct, and that OFGEM requires suppliers to base monthly fixed Direct Debit amounts on an accurate and reasonable basis - which obviously could mean not on the supplied EAC when appropriate. Where the reported EAC does not reflect reality for the individual customers then it should be challenged vigorously. Its up to Suppliers to set Direct Debits reasonably in relation to known facts.

I think you have summed it up correctly.👍

So when will the jury render its verdict. I’m ready to pass sentence in the event of a guilty verdict.

If I was Scottish (which I am on my mother's side) I think the verdict would be 'Not Proven' 😄

I think the EAC system for consumers is not fit for purpose.

Tonight's the night. I'm going to switch the fridge off and see what happens to the overnight consumption. The fridge is a nice colour and matches the washing machine so I don't think I'll be allowed to ditch it if I can't find a new one the same colour 😂

When you wrote 'tonight's the night' all sorts of things were going through my mine - glad you were talking about the fridge. 😄

Do you not have a working IHD that you can check the 'usage now' function? Wait until you hear the compressor going, record that wattage number then turn the thing off and see how much your baseline has dropped and there is your draw at full compressor usage. Repeat when the fridge is on but compressor off so you know the power draw on/off. Then you need to check that, when switched on, the compressor is not stuck in the 'on cycle'. At least then you will have an idea of the draw just on the 'problem fridge'. 😎

Have you checked the manufactures energy fiche for this fridge?

Similar thoughts went through my mind when I typed the first three words 😂

I do have a working IHD. There are a few checks I can carry out but wanted to try this one first. It takes almost no effort and causes very little inconvenience. Baseline consumption between midnight and 7am is very stable at around 0.21kWh every hour so it will be interesting to see if that changes significantly overnight tonight. I will look at how live consumption changes when I switch on in the morning then decide if I have to do any more tests.

Exciting 😂
