As you may remember, I did write to Greg J. a while back suggesting that Solar +Battery + Heat Pump users might be considered as a group worth a special tariff and an assistant replied thanking me for me suggestions and that he would forward the details to the appropriate department. I might go blue in the face meanwhile but one can but hope, for as I pointed out, Heat Pump users might well equate to some EV Car users’ consumption.

Yes, I have not yet done real calcs. But it seems that even basic calcs show that it does not work. 

I called Octopus and outlined the case. I buy at 3.5p with the EV tariff at the moment. Cosy would mean the lowest rates would go to 14p. So a 4x increase. As we can buy gas at 7p, so 14p keeps the heatpump cost below gas.

But for us, all our consumption would cost 4x. So I would give this up for the whole year to get some benefit for the fewer months our heatpump would be relatively busy, I cannot see the numbers stacking up reasonably. 

But I could keep overnight with a similar rate but also get a 14p rate or even a bit above (for like 3 hours in the middle of the day), it would be worth. 

We discussed this before, which is impacting a growing number of heatpump cases. And we know, people that use one renewable technology are much more likely than the average to use others.

In fact in these milder temperatures I can export to Axle VPP (very lucrative) and export to Agile Outgoing Octopus, admitably only for pennies.

If i could only charge the batteries at very cheap rate in the night on an EV tariff then my batteries would soon run out before the next charging slot. So happy with Cosy as is and probably that demonstrates the varying tariff needs, in my case without an EV or solar but with Heat pump and batteries.

At the moment, I just export at peak and with the "Ormuz effect", I think we get over 20p/kwh (enough to offset the general consumption, even some of the EV), as below. No complicated config involved and it has been working without touching it for months.

Is Axle VPP working as a "zero hours contract", where they can have the right to use your battery but only pay you on the days that they do?
