Electricity price predictions

When the energy cap comes up for renewal I think it will rise to 26.5p per unit, any thoughts of the collective?

@kevh Blimey you got a good rate. Here in the NW our cosy off peak rate was 14.3 and I had to fix and pay an exit fee to get that. We managed to stay off peak for all but the 4 coldest days with a 13.5kWh battery, cycling it like crazy. I’d need to triple that capacity to move to an EV type overnight tariff, not viable for me.

As an example, my teeny 5kWh battery saw us through winter at an average cost of around 14-15p /kWh, easily outpacing what we would have spent on gas (calculated by direct comparison to last winter and also comparing the Cosy9 output to current gas prices at a SCOP of 3.66).

Thats impressive, I averaged about 20. I have been assuming I need a largeish battery (10-15kWh) but maybe I should re-evaluate the Cosy option with a smaller one!

4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.

I have just rechecked my figures: I averaged just on 14p overall, it was just over 15p on the 9 February bill, and back down to 14p on 9 March bill

I am still chuffed.

And if Octopus reduce the cheap windows I am knackered.

@kevh You must have worked that battery hard, that’s what they are there for. The triple period is essential for me, a double wouldn’t work without more capacity. On the coldest days it was guzzling 70-80kwh, gave me nightmares.
