Most importantly, does anyone know where Octopus go pricing is likely to go in the coming months?!
“For the new Go Faster rates, the day rate would be 29.82p/ kWh and the night rate would be 8.25 p/kWh as you get 5 hours (rather than 4 hours) of off-peak energy. You should get an email confirming your new rates shortly.”
AS a big electricity user it seems to make sense to go for storage and time-shifting, problem is my leaf 24kwh battery is not big enough, can only shift about 2-3 kwh per day on average after own use of the car and round trip losses using the V2G kit from the trial as V2H.
Options seem to be:
1) Batteries - 12kwh cost about 5.5k and last ?10 years
2) Bigger battery leaf 40kwh - but then have to offset higher annual depreciation compared to current leaf and also any value on having a newer car with a better range but deduct any peak use when the car is out from potential savings. This could also give about 17kwh per day storage
3) Possibly left field but second 24kwh leaf which will give a similar 12kwh of storage to the batts, two 24kwh leafs may depreciate less per year than one 40kwh big battery leaf.
One possible advantage of (3) is that if leccy prices go back to historic levels I can just sell one of them whereas options (1) and (2) I am locked in.
