My calculation is also out by just over 1% to the OVO email - BUT in my case it is my calculation which is the higher of the 2.

I have 9.88% on my spreadsheet, OVO have 8.77% in their email.

By either one I comfortably met the target.

I do have a days data missing for 27 Dec, but that shouldn’t make a full 1% difference.
I might take a look at what difference adding in the bank holidays makes.

PS. You may want to edit all that whitespace out of your post, if you can.

This is likely to have cost me as well - this whole scheme does seem well thought through and certainly offers no transparency 

I’ve just had a word with the Support Team, they’ve raised a case on my account to get mine checked. Pretty quick to get through if you use Live Chat right now… Even if the agents do suffer my Rickroll pranks as a result… :)

We’ll let the Forum Mods know about this as well - they might be able to get someone to dig deeper and wider.

Thanks for this pggima. I think the Dec fig is out too. I've made the target but by a much finer margin than I thought it would be. I'll check against my own figures later. 

I tried editing the post but every time I deleted spaces and reposted it the white spaces just got bigger and bigger…

I've found my spreadsheet to be accurate since PM started as follows:

Sept: me - 11.07%, ovo 10.79% (-0.28%)

Oct: me - 11.23%, ovo 11.43% (+0.2%)

Nov: me - 13.19%, ovo 13.30% (+0.11%)

I wish the website would give the kWh figures for each 30min period to 3 decimal places, as this introduces an error of approximately +/-0.05kWh each day summing the 48x 30min periods when compared to the daily totals.

No worries. I’ll get a Forum Moderator to help fix that post for you. This is free and won’t result in a black mark on your forum account. :)

I have to disagree with you. The scheme is well thought through, just may have some bugs that in fairness they seem to care about fixing.
The whole point is for each person to make a small change to their routine, to reduce the peak demand on the grid which usually occurs between 4pm and 7pm.
The grid has to be sized to cope with the peaks, so if you can lower the peak, then you can save many many billions in infrastructure upgrade costs, which you as the customer would have to pay for through higher bills anyway.
So it is very much in yours and everyone else's interest to do what they can to reduce personal 4pm-7pm consumption, and it really isn't terribly difficult to do, to both benefit from £15 a month credit currently, but also big picture avoid many hundreds being added to your bill in the future to cover the costs of upgrading the infrastructure to cope with the peak should no one decide that they can be bothered to participate in schemes like this.
Cant be bothered, I’ll have your £15 then if you don't want it.

You’re not alone. Several of us use a third-party aggregator to get the accurate usage data from; I use this one, which makes it very easy to get the data I need with just a couple of clicks.

There are a few reasons why you may see discrepancies apart from the rounding errors. 

• Missing data. There must be exactly 48 values for each weekday. Any day missing even just one half-hour’s figure will be discarded.
• Late data. If the usage figures for a day haven’t been applied to your account by 13:00 the following day, the day will be discarded.
• Others I either forgot or never knew about.

I have tried and failed to match my own December figures with the progress report dated 19 December. I’ve tried excluding one day when we had a power cut, but I’m still not able to match precisely, so I suspect there’s at least one day when its data arrived too late for it to be included. OVO’s half-time score was 4.82%, but the closest I can get is 4.814% on 15 December, if I ignore the power cut day.

I’ve yet to see whether I earned the reward, even though my final figure for the month was 4.758%. 

Hey all,

We’re sorry to hear some of you have had emails to let you know you didn’t meet the recent Power Move target. 

We’ve had a reported issue from the Power Move team where Boxing Day was included in the calculations when it shouldn’t have been. 

The team is currently working on getting corrected emails out to everyone impacted by this error. You’ll soon receive an email with an updated % and an explanation of the issue. (Please note, this does not mean that all recalculations will now meet target where they failed previously). 
 

We’ll keep this answer updated with anything further from the team.

Any update on these emails going out? I haven't received anything, and our bill date which will include the December credit when correctly calculated is coming due.
I would greatly appreciate a response at your earliest convenience.

Unfortunately without an in-home display, which I apparently cant have as I have old SMETS1 meters that have been migrated to DCC, I cant use these 3rd party aggregators as they need the MAC address to confirm I am the account holder.
I wanted to sign up with these aggregators as they have superior data accessibility of my OVO account than OVO will provide us with…

I have made 2 subject access requests to get the 30min data for both gas and electricity dating back to the transition to 30min reporting in 2022, but both times they have only provided the daily totals. They seem unable to read and understand the VERY clear requests…

I went through a process to get OVO to determine which in home displays would be compatible with my meters. I located a second hand one, but then unfortunately when actually trying to link it to my meters, OVO then told me that as they have been migrated to DDC, no in-home displays will work and it is impossible.
 

There’s a tool at n3rgy data Smart Meter check which will probably reveal the migration status.

If the meters are NOT on DCC however, that tool will likely return a not found error.

If they ARE on DCC, let me know and I’ll give you some options. Do not try to use second hand IHDs - they won’t work and we strongly recommend you send them back for a refund.

I’m not quite sure where this comes from. My situation was not the same - I have no gas meter, and the IHD I had came with the meter six years ago. But I did have a SMETS1 electricity meter with its matching IHD, and the IHD continued to work flawlessly after the meter was migrated to DCC. So there is no fundamental barrier between having a migrated SMETS1 meter and having a working IHD. 

It may be that current IHDs won’t work with this sort of meter, but that’s a different issue. Blastoise knows better than I what the options might be - whether an old IHD could be paired with your meter, for example. But the way you’ve presented the situation doesn’t match with my own experience.

And existing IHD paired to your previous meter can be migrated - but not from S1 → S2 or S2 → S1.

An ebay purchased IHD is ineligible for transfer. As a rule, we also don’t provide support for unauthorised IHDs (such as eBay purchased ones) via the Forum and OVO Support won’t be able to help either.

Hey @pggima,

The Power Move team have advised all affected customer should have received an email, could it have ended up in your spam folder? 

If not, please private message me with your account details and I’ll let someone in the team know.
