Octopus EV charging rip-off coming end January

mark_cycling00

You only get 5 hrs per day with EDF. So doesn't seem too bad 

Keep_pedalling

I assume by normal you mean a 7kW fast charger which will deliver around 42kWh in 6 hours so you should get somewhat more than 100 miles out of that charge unless you are driving a thirsty beast, and assuming you are not running the battery down to 0% on your drive home you will have more in reserve. 

You can thank the people who were gaming the system for this change.

Are you setting the smart charge via your EV or your charge point? If the latter you should be setting it to the amount the the % of charge needed to take it to 100% not to 100%.

A Tesla Model 3 or Y will easily do 3 miles per kWh. Should be more like 4 miles per kWh on average over a year.

That's  at least 126 miles per day, about 46,000 miles a year.

Should be enough for most domestic customers and this is a domestic tariff.

Hardly a rip off.

If you are a business then that is a different matter.

Another 20,000 miles will cost be about an extra £1,500 pa

The total cost would be (15,300 kWh @ 7p and 6,667 @ 30p) around £3,070 giving an average rate of 14p per kWh

Not that bad if you are something like a taxi driver?

Probably not what a domestic tariff is aimed at?

Octopus EV charging rip-off coming end January

OP is correct, those who have been ripping Octopus off will no longer be able to come end January. As a happy Cosy user I trust my prices will plummet.
GO OCTOPUS.

Here’s how it’ll work:

• Intelligent Octopus Go customers will continue to receive 6 hours of off-peak electricity for your whole home between 11:30pm and 5:30am. Guaranteed, reliable, schedule-friendly off-peak savings.
• Plus up to 6 hours of super-cheap smart charging every 24 hours – these may be during your home’s off-peak hours (11:30pm-5:30am), outside those times, or a mix of both.
• Whenever the 6 hours smart charging is scheduled outside your off-peak window, the electricity for your whole home will also be at the discounted rates
• If we need to schedule more than 6 hours to reach your target charge, only the first 6 hours of charging will be at the discounted rate – extra half-hours will be charged at your Bump rate (even if they’re scheduled during the off-peak window).

Can still charge for 6 hours during the peak daytime rate of off peak rate. Subject to Octopus allowing your schedule.
So as before I will just be doing a little & often. 
All within the rules, which have not changed at all from what they were before. Only now Octopus are monitoring them.

One good thing that has come out is that the likes of OHME & other charger suppliers have been caught out throttling supplies when they should not have been doing & causing more of a issue to Octopus than users were, as many that people believe were gaming the system were not. Thanks to the charger manufactures slowing the rates, & causing longer charging sessions.

I believe it is more a case of Octopus staff not fully understanding the way that Kraken was working with Ohme and Hypervolt. So those two were taking the scheduled charge and spreading it across the whole half-hour to reduce grid load, but as that increases the charging time it was not compatible with the plans for the end of January, so that behaviour has now been changed.

Similarly it is easy to see the difference between long periods of low-rate charging and the intermittent lower rates being caused by spreading some sessions over the whole HH, so I doubt it was really responsible for much of an impact on the level of gaming they were detecting.  

Spreading the charge over the HH didn't ever increase the number of HH segments at the low-rate, the gaming of the system did...

I'm still waiting for Octopus to explain how they're going to charge for any smart charging slots greater than the 6 hours allowance that fall within the 23:30-05:30 off-peak period for house period.

They can't directly bill based on the car/charger reported usage, as few are certified to do so.

The only way I can see it working is that they charge the peak rate for those slots (even if in 23:30-05:30 period), and then credit the account based on the difference between the EV charge usage reported by car/charger and the smart meter usage recorded during that slot.

Isn't that still billing based on EV charger data?

Both methods end in the same result and both use the EV charger data to arrive at the amount to be billed.

I don't believe so. The actual bill (kWh * rate) has to use a kWh from a certified reading (smart meter).

So, they could bill on the smart meter reading for the overnight slot, and then credit the account based on their own calculation. Since its an account credit, its not legally billing on the car/charger reading.

This is how DrivePack works i believe (would be good if someone can confirm).

They won't end in the same result as the car/charger reported usage will not contain charging losses.

The difference would probably be that it was a variable discount offered. Billing must be based on a metered supply, but suppliers are free to offer contractual (or gestures of good will) discounts off that amount, so my guess is that it be billed at full price, but with a discount offered. I am of course just hypothesising, equally they might just apply this whole mess to the very obvious culprits and only charge those people during the six hour window.
