Octopus Export : Fixed Rate vs Agile?

anon_ymous

I'm with Octopus as my energy supplier, and they appear to have this. I'm not sure what's best RE: exporting back to Octopus when selling excess solar. 

It appears they pay 15p/KwH as a fixed rate for export which is better than the SEG

In the last year agile export has been best. It's likely to stay that way for a while.

I'm happy with 15p/kWh fixed. Saves having to think or plan.

Thanks. I'll sign up for the agile tariff

You can switch between them every 30 days, all it takes is a phone call (did it a couple of weeks ago)

Agile looks to have been rather good during the cold spell, up until Dec it was struggling to match fixed except for a couple of hours most days.

Is there a risk that the fixed SEG tariff could be replaced by a lower rate while you're switched across to agile? A low risk I should imagine, but their rate's significanly better than anyone else's and there's nothing to stop them reducing it.

Do you have a storage battery with your PV system? How much are you prepared to work it? I have Economy 7 with Octopus. Current off-peak rate is around 15p(going up in Jan to 16p). If you charge your battery at the offpeak rate in the winter, and then watch the Octopus Agile export rates for the day (and your battery is capable of a "timed" export) you can choose to export when the rate is the most favourable . In the south this is usually between 4.30 - 5.30pm. I'm hoping to cover most of my import costs by a short export at the best time. Only really works if you can survive to the next off peak charging period on the juice left in the battery after conducting the export!.

I've just got a 3.3KwH system so far tbf, and I wouldn't mind charging it at night time and then exporting any excess solar
