@tim441 Thank you Tim, I was not aware of the changes to Outgoing Fixed - doesn’t sound too promising as a money earner next spring and summer does it? Today, I saw solar production of 7 kWh’s and that is at least 5 kW better than any day in the last gloomy fortnight! I was looking at the possibility of changing in the spring to Flux and thinking that as far as I can see, the present Outgoing Fixed deal was still a better deal…. and now…who knows???? Toodles.

Please, if any Agile user has the time to check their consumption and average price, I would be delighted to know.
I am keeping tabs on the published ‘average off-peak’ rates but wonder if the more savvy user (admittedly, those with time on their hands or an automation procedure to carry out the task for them) has been able to ‘better’ that average. My Cosy tariff lowest rate is still under 13 pence per kWh and I have not seen anything to approach this according to Agile Prices daily listings. Regards, Scroogely, Toodles.
These are our figures. We have solar but no battery.

Just a bit of clarification if you don't mind. Are your agile costs including or excluding standing charge and are they for your import only or import and export together as a net figure?
105 m2 bungalow in South East England
Mitsubishi Ecodan 8.5 kW air source heat pump
18 x 360W solar panels
1 x 6 kW GroWatt battery and SPH5000 inverter
1 x Myenergi Zappi
1 x VW ID3
Raised beds for home-grown veg and chickens for eggs
My intention is to come back to this topic in January once I have a full 6 month’s worth of Cosy Tariff consumption figures but, meanwhile it looks as though a very nasty fly has landed in the ointment in the form of a massive reduction in the saving sessions rates and we might only see 10 - 20 % of the amount offered last winter😒. Regrets, Toodles.

@toodles With you having a battery, it will be nigh-on impossible to look back and decide which tariff would have been a better choice as your usage profile throughout the day depends on the tariff throughout the day. What would be useful is a regression algorithm into which you could feed historical tariff prices, hourly electrical load and battery capacity 😎
@ianmk13 My intention is to take advantage of the grunt work carried out by Agile Prices UK and attempt to find sufficient time each day to equate to charging the battery for the day’s needs. There will be a lot of ‘averaging’ as Agile is a moving target and never very predictable day to day.
I’ll have to base the consumption on an average daily figure as the variability of the weather is, I think a step too far to calculate! I know the fixed rate for Octopus Cosy and thus will be able to calculate the Cosy Tariff cost per month and compare this with equivalent amount of Agile Tariff chosen from the cheapest HH’s. Of course none of this will take the ‘Faff Factor’ into account and will assume that any comparisons are based on a similar battery capacity.
The battery capacity and charge rate may be more crucial in Agile than Cosy as there are often many hours of higher rates in Agile before another acceptable charging period appears!
I must stress, I realise this is all very approximate and in many ways probably unrealistic, however, we are dealing with such a myriad of variables that I feel this will at least be a starting point. I do not have the visual acuity to work with spread sheets and graphs - even working on an A0 landscape sheet would be of limited usefulness if printed / displayed large enough for me to read say 3 numerals in a cell.
For all the reasons stated above, the report I produce will be illustrative only and not necessarily of great merit in other circumstances but - hey it will give me something to exercise my old grey cells over!😉 Trgards, Toodles.

@toodles Yes. I'd been giving this some thought since posting. Something like dividing the daily average or max energy consumed by the battery charging rate will give an approximation of the number of hours per day battery charging requirement and then find the cheapest slots each day during which you would have most likely charged the battery. I might give that a try this weekend. I'm on Intelligent Octopus Go and, with barely any solar PV at this time of year, the battery expires between the cheap periods.
@ianmk13 Yes, we are thinking along similar lines; I have the capacity for 27 kWh and am able to charge at up to 10 kW. The spread of the 3 cheapest periods of Cosy (3 hours, 3 hours and 2 hours) allow me to keep some charge in the battery and as yet, I have not needed to resort to using the grid at even the middle rate periods. 😊 I think it may be a tough nut for Agile to crack and come out lower cost (not even considering the ‘Faff Factor’) Regards, Toodles.

Thinking about installing a heat pump but unsure where to start? Already have one but it’s not performing as expected? Or are you locked in a frustrating dispute with an installer or manufacturer? We’re here to help.
