Octopus Saving Session

TBH - I wouldn't mind if they'd just used the £2.25 in place of £3 , but to adjust down the kw saved certainly seems dodgy

I wouldn't go as far as 'dodgy', but it suggests the kWh saving has been calculated on the webpage from the Octopoints rather than the other way around. The error is in the calculation of Octopoints, so perhaps £2.25 needed to be changed to £3.00 in two places, but the adjustment was only made to one part of the calculation.

I'm hoping this is a simple mistake like you say and it will be corrected. 
The results on the website display right for the sessions on 23/01 & 24/01 at £3.37 & £4.00.

So I got the little ghost for the third time in a row. The first two times, I wasn't surprised because I wasn't in during the IDA period to increase my demand above my PV generation. But the final session I was, so I am a little disappointed to have got the ghost again. 

I can see from my Octopus consumption data that I have HH readings for the IDA period and the saving session itself. Could it have been a reading from the previous 10 days that is missing and causing? Could it be the same reading that caused 3 ghosts?

I'm going on a ghost hunt...

You need a minimum of 5 eligible days to set your baseline consumption for a session, and these need to have the full set of 48 half hourly readings, as does the day of the session. Do you have any missing data as reported by https://energy.guylipman.com/sm/admin?source=octopus

Thank you for sharing that page.

I have 48 gaps - the whole of November 5th. So shouldn't be effecting my saving sessions now?

Edit to add that I have some zero readings on the session days, but only a half hour at a time.

No, any gaps that far in the past won't make any difference. If by "zero readings" you mean your consumption was zero during those periods, then that shouldn't be a problem either. Zero consumption during the session is ideal!

That's what I thought. 

Unfortunately the zero readings were during the IDA period. But only one of the 6 HH slots. My PV means that I have started generating more than I use during the afternoon, especially if I am not at home.

So, it is starting to look like it wasn't my data that was the reason I got the ghost. Any other ideas and is it really worth pursuing? Edit: it seems a few people have had strange results for this last session.

I haven't run the calculation, but am surprised at the result.  Apparently I saved 1.51kWh, compared with 2.5kWh for the previous two sessions.  I'm not aware of doing anything differently.

It's worth following up with them, as they should have the readings they needed to calculate your savings. One possibility is that some of the readings have come through after they attempted to calculate your savings. If that's the case they may be willing to re-run the calculation for you.

The "strange results" seem to be a global problem, where Octopoints have been miscalculated (they haven't applied the increase from £2.25 to £3.00 per kWh for this session correctly). A few people have mentioned it here and I've seen one mention on Twitter.

Would a 2.01 kWh saving seem more reasonable? That is the value you would have got if we are right about the error Octopus has made.

Yes, that would feel about right.  Hoping that a resolution is found.
