Come the day when a huge proportion of EV owners charge at night, that’s likely to become a ‘peak’ timeRemember, Go off-peak rate isn't quite "nighttime" rate. It's a couple hours and a bit less than the "normal". The Go Faster tarrif's are varying off-peak lengths and start times. Because I'm on Go faster that starts at 8:30pm, my true "nighttime rate" ends up peak rate.
The maths takes a bit if time, but I worked out what my total costs would by taking into account the different off-peak start times, price and durations.
When my current Go contract ends, the maths does not look quite as favourable with the increase in peak rate - Go is good for most, but always be cautious.
It'll be interesting how comparison sites will compare tarrif's as I think this trend of off-peak being very different start times will only increase. The view that the middle of the night is cheapest is fast fading.

it’s like us all putting a kettle on during the adverts, but much worse!
Indeed, and that’s why there is pressure towards smart charge points and smart meters. This provides the opportunity to spread the charging over 24 hrs picking the best times to keep the grid balanced. Instead of a problem the ev charging actually becomes a solution which benefits the grid. In fact it’s already doing that, which is why the likes of Octopus can offer their cheap night tariffs at the moment.Come the day when a huge proportion of EV owners charge at night, that’s likely to become a ‘peak’ time

As long as everyone avoids the 4-7pm peak, I don't know if it matters that much when we end up charging our cars. Obviously people that drive their car to work will need to charge overnight (although many could just as easily charge at work), and overnight is certainly the most convenient time, but I'm sure there are and will be plenty of people that would have no problem charging during the day if the incentive was there. It seems like we are already well and truly on our way to have all kinds of clever systems to ensure power companies are able to incentivise / control charging times. I've owned an EV for under two years, and I've already been on 3 or 4 different schemes (just having moved to Octopus Intelligent), so I'd say it's a very lively marketplace!Hence tarrif's that spread off-peak hours throughout 24 hours become normal, otherwise it's ping pong peak rate. Go was a first step. It just means that comparing prices becomes more complex, there is no longer just one or two rates to compare, the hours are an important part of the equation of value.
Electricity rates are sky-high, so most people are in for disappointment/shock come renewal time. I think Go remains just as good, because the energy consumed charging an EV dwarfs the regular household consumption, so as long as the 5p rate remains low, the peak rate can go higher without as much impact to the bill.When my current Go contract ends, the maths does not look quite as favourable with the increase in peak rate - Go is good for most, but always be cautious.

Ah yes, indeed. Which is where hopefully the likes of Octopus Intelligent will step in and charge when it's greener.If you are looking at your pocket maybe, but if you are looking at the environment, there is

National Grid ESO have developed a Regional Carbon Intensity forecast for the GB electricity system.www.carbonintensity.org.uk
So avoid plugging in tonight late evening unless absolutely necessary for example

Could I ask if there is a model code next to EDMI, something like Mk7M.Ours says EDMI on it - and it has 4 cables coming out the bottom - if that helps?!
I've PM'd you a picture of itCould I ask if there is a model code next to EDMI, something like Mk7M.
Thank you.
Thanks, it uses the EDMI for the communications and the Smart Meter is a 4-terminal Aclara unit, although my research suggests that they make a 5-terminal. one too. I now just need Octopus to confirm that they can fit the AClara1415 and that their systems will manage the off-peak switching to the 5th terminal.I've PM'd you a picture of it
NopeGuys, I need help calculating my energy costs for a Tesla to prove to someone that Octopus Go is cheaper than other suppliers.
Let's assume 11 hours to charge a Tesla Model 3 LR from 0-100 (theoretical, I know, as we won't be at 0% exactly).
Say we are on Go Faster which is 5.5p per kWh for 5 hours from 23:30 until 04:30. The rate is 16.03p per kWh for the off peak times.
Plug in at 20:30 the night before to be ready for 07:30 the next day.
This means:
20:30 - 21:30 = 16.03p
21:30 - 22:30 = 16.03p
22:30 - 23:30 = 16.03p
23:30 - 00:30 = 5.5p
00:30 - 01:30 = 5.5p
01:30 - 02:30 = 5.5p
02:30 - 03:30 = 5.5p
03:30 - 04:30 = 5.5p
04:30 - 05:30 = 16.03p
05:30 - 06:30 = 16.03p
06:30 - 07:30 = 16.03p
Total = £1.24.
Have I done this right? £1.24 to charge a Tesla from empty to full on Octopus Go Faster?? £1.24???

Unfortunately not. You'll be charging at around 7kWh - so it is 7 x 16.03p for each hour.Guys, I need help calculating my energy costs for a Tesla to prove to someone that Octopus Go is cheaper than other suppliers.
