Power Move Calculation For September 2024

I’ve had a similar problem.  I monitor my usage using the Bright app and the totals are usually very close to the OVO numbers.  But in September 2024 I’d calculated my consumption during peak hours was 7.08%, but the OVO total says 7.91%.

Your calculations are undoubtedly correct, but the difference is likely to be that you’re basing them on some bits of data that weren’t available to PM at the time. Sadly, you’ve no way of knowing which days might have been discarded because PM didn’t get the half-hourly (Hh) figures until it was too late to include them. 

Bright pick up the Hh data more or less on demand, or a couple of times a day if the app is always running. OVO usually request data once a day, repeating the request later if it produced no result or an incomplete one the first time. However, there has to be a limit to the number of requests they can make and at what intervals, and PM can’t wait indefinitely just in case some data that were missing eventually turn up. So some days may get discarded. It’s a bit of a lottery, because it could work to either your benefit or your disadvantage. It looks like you missed out this time, but next month could bring a different result.

I’ve just added up the numbers using the usage data on the OVO website.  That also produces 7.1%, the same as the Bright data.  So if there were instances of data being missing then the gaps must have been filled in subsequently.  While running totals may well be a lottery, I consider PM to be a contract, and I expect OVO to honour it.

Now that PM has moved into Beyond, and now promises weekly progress updates that should help spot if/when any days data has not been included in the calculation that week.

Yes, but you’ve no way of knowing whether a specific day’s data arrived at OVO in time for them to be included in the calculation or not. 

Did you use the webpage figures with their 10Wh precision or the ones from the API precise to 1Wh? The difference can be significant. Bright and OVO should have exactly the same data, because they’re immutable once they’ve been stored in your meter.

A word of advice. Power Move isn't a contract, nor is it linked to the core supply contract. It runs purely on a best effort basis. You don't technically have the same rights over it as you do for the supply contract itself. 

Hey @peteyshep 

I’ve passed your comments along to the team. They are still looking into the matter as a whole and hopefully will have some more insight for us soon.

We’ll pop back here as soon as we have an update.

Is there any update on my question?

Hey @PowerM0v3 

I’ve spoken to the team who have advised they’re still looking into this. They should have more information later in the week.

As soon as I hear from them, I’ll update you in this topic thread. 

Just to note that today I’ve also got the half-way progress email.

So it looks like we will be getting both weekly updates in Beyond, and the half monthly email - at least for now.
