Is there a way of asking OVO to show me their Power Move calculations?

Is there a way of asking Ovo to show me their Power Move calculations?  I work out my usage and percentage, based on the data available to me on the Usage page of my account, and compare it to Ovo’s mid-month and end of month figure.  The mid-august figure, received by email today, is wildly different from mine.   We never agree exactly, but we’re usually pretty close.  I’ve double checked my figures and I think they are right.

    Hi @Fern3,

     

    The team have got back to me and said:

     

    “They should be able to take their usage from the data they can see in their accounts and follow step 6 on the FAQ here:https://www.ovoenergy.com/power-move-faqs”

     

    We’re going to reach out to get some account details from you to pass over to the team so they can look into this further. Look out for a private message here soon: https://forum.ovoenergy.com/inbox/overview

    Your calculations won’t necessarily always coincide with OVO’s, because the data available to you may not be exactly the same as the PM people receive. There are a couple of constraints: 

    • There must be 48 half-hour figures for each day. If a single one is missing, the entire day is discarded.
    • The usage data must have been received before a cut-off time. This used to be 13:00 the following day, but there was talk of delaying it a bit further. You can’t really know when your own figures were retrieved, so there may be days discarded for this reason.

    You can check your own calculations by using @Tron Burgundy’s excellent little bookmarklet: GitHub - Tron-Burgundy/Ovo-Power-Move-Calculator. This collects the underlying data from your account, so it has 3-decimal precision. Sadly, it can’t allow for the ‘delay in arrival of the incoming data’, so it won’t necessarily match the official results precisely.

    Hi @Fern3,

     

    I’m going to check with the team to see if there’s a way for you to get a full breakdown of their calculations. I’ll be back once I get a response from the team.

    If a weekend day is then ignored it skews everything. 
     

    Sure, if a discarded day isn’t a weekday, the omission will have a slightly bigger impact than if it were. That’s the luck of the draw, I’m afraid, and I can’t really see any way around it. Even if a whole weekend day were missing from the final calculation, though, there would still be more than 96% of the offpeak hours to count.

    I suspect that the number of instances of a missing weekend-day causing the customer to miss the target is vanishingly small in the overall picture. Do you think this is what happened to you?
