Half price IOG tonight

When can we plug the EV in?

I left selling first on my inverter settings so batteries have been emptied... I need an Arne Slot. Desperately.

No one actually knows. I guess after 11am is safe.

In sunny weather I don't need a cheap-slot indefinitely! However, I'll probably start force-discharging my batteries into the grid for some extra 15p/kWh and use my appliances/cook/charge the car in a "gamed" cheapslot.

I think I will wait til 11am and hope the sun covers the house load... (The things we do for pennies... hehe)

I was messing around with CT clamps, Home Assistant and dumping excess batteries before bed. Never mess with inverter settings when tired!

So I ran through the night on battery power. Didn't plug the car in from just before 1100 yesterday. Battereis got through effortlessly even with the AC running low-and-slow all day. Sun is up and shining now and already covering the household use as well as putting 1.5kW into the batteries.

I wonder when we'll have clarity on how the credit will be calculated. My guess is that they'll compare your usage in the 2330-0530 slot from Monday night to tuesday night and credit you the difference. But that is just a guess.

Why run the house on your batteries when Octopus were offering to do it for 50% of 7p = 3.5p

50% off electricity for your EV and home between 23:30-5:30 tonight.

Yup, that's right: we'll give you 50% off your already super-cheap off-peak rate tonight, as long as you...

Plug your EV in this evening (Monday 28 April) AND
Don't plug in your EV tomorrow evening (Tuesday 29 April)
​
Give the summer wardrobe a wash, get the wheels charged, or set the dishwasher to task after a spontaneous BBQ.
Tick off the list tonight and save while you’re at it.

Stinsy is talking about the "Don't plug in day" as he thinks Octopus might offset what you use on the "don't plug in day".

Thanks Nowty, you've gotten it.

John: The offer from Octopus was double-edged. It was half-price on Monday night, but only if you don't plug the car in on Tuesday night. We have no idea what that means in practice. However my guess is that they'll calculate how much electric you used in the cheap slot on Monday minus the electric you used on Tuesday and give you a credit for that. Hence I used loads on Monday and nothing on Tuesday. However all this is conjecture, Octopus are yet to communicate the actual mechanism...

My interpretation was that if we plugged an EV in on Monday night, everything that we used between 2330 and 0530 would be at the 50% rate as it specifically said it was for the home and suggested that other heavy loads could be performed, eg dishwashers and washing machines. The only condition was that an EV was not plugged in the next evening. Nothing about base line loads.

I am aware that other energy suppliers detect the EV, similar to how Octopus does, and only gives the cheap rate to the quantum of electricity measured and as reported as the charge by the EV charger. It might be Eon or EDF but I cannot remember.

Who knows what Octopus meant. They didn't say! All they said was "plug your car in tonight and don't plug it in tomorrow".

EDF had a tariff that required their own special charging point that reported the amount of energy going in to the EV to EDF and they credited your bill accordingly.

Octopus now has a tariff that gives unlimited* EV charging but no cheap rate for the house.

*predictably no one cares about the meaning of words so "unlimited" doesn't actually mean unlimited, there is a limit!

We exported enough power yesterday to generate a tenner (69kWh). Only the second time this year we've managed that.

I'm going for the PB again tomorrow, the crisp twenty note from the Octopus awaits.
