Power Move Calculation For September 2024

@PowerMover2053 During the last winter PM season I ran an independent calculation in a spreadsheet so I could track where I was in relation to the target on a day by day basis rather than just getting a mid month email telling me where I had got to. The rules then didn't include weekends or Bank Holidays so the calculation had to be right and generally I was within about 0.02% of the figure that was presented to me. I was well away from the boundaries so your situation didn't occur. I did find differences at the beginning but I found errors in my spreadsheet and corrected those. Of course, if there was a 0.02% error and you were 0.01% away from the target then that would be a difficult situation. Given that OVO is applying the same method to everyone's account I would tend to trust their calculations. Another point is that Half Hourly figures on the OVO data presented to you is rounded to units of 10Wh (0.01 kWh) whereas I think the meters send data in Wh to OVO. As far as I know the meters themselves are only accurate to about about 1%. Someone might correct me on that.
