I've just been looking at energy tariffs again. I'm on Octopus Flux at the moment which has been working quite well for the last year (since we got the solar panels and battery installed) and I've got used to the schedule, but now I'm eyeing up Agile, which seems to have been having negative import prices quite a bit over the last few days. I don't know how likely that is to continue, but if it does it could be really good as it would very much financially reward deliberately cycling the battery to soak up negatively priced energy to re-export during peak time, while on days without negative prices (or at least without a large price difference) it's likely best to save energy from the solar panels to use locally. Hmm! Is it worth the hassle of spending time each day looking at the following day's graph and scheduling things to match? Sounds like quite a time commitment, but might potentially reduce bills a *lot*.
