MSE Guide - Electric vehicle energy tariffs

born_again

Just posted this in another thread.
I'm on Intelligent Octopus. Bonus you can get off peak costs @ Peak time if charging car.

Broken down
7.14p/kWh   206.2 kWh £14.731 Off Peak When not charging car off peak use is under 1kWh (so 30kWh). All the rest were actually in the peak time (bonus) 7 car charges.
24.60p/kWh 170.7 kWh £41.994 Peak



This is my average unit cost for June (as above). 376.9kWh @ 15.05p/kWh Normal daytime rate would be 22.28p/kWh on IO. (£78.52 inc standing charge)
Variable rate from Octopus would be 21.22p/kWh (£98.64 inc standing charge)

So a £20.12 saving.
To be fair did not charge as much in June.

I found it an interesting article, but not quite as accurate as it could be. 
I'm on intelligent octopus go, this gives me cheap electric between 11.30 - 05.30am.
Unlike OVO anytime which is only for EV charging, IOG is for ALL electricity used. 
So if I use the heavy duty items along with my EV, all my usage would be 7p per kWh (Inc Vat). (Washer, dryer, dishwasher etc)

When you look at the price per KWH it's broken down by ev average charge but in reality you could save more if you have the right charger and car for IOG. 

All the quotes Ive looked at would cost me 100's of pounds more because these factors are not taken into account and cannot be quantified. Plus unit rates are higher.

I use quite a bit of electricity, I have 14 solar panels and 4 kwh battery. My DD per month is £86 (in winter I charge my solar battery at night to use the cheapest electric during the day)

Annual quoted usage
3900kwh electric 
7000kwh Gas. 

I hope this helps you take the extra factors into account when choosing energy suppliers. 

Intelligent octopus go rates (Inc vat)
Daily rate 49.119p
Peak rate 23.896p
Off peak rate 7p

DOE’S ANYONE at moneysaving expert ever read these comments.?

despite being ‘updated’ regularly these best buys are well out of date, use flawed calculations of use. Take no account of load shifting, panels or batteries and EXPORT have incorrect data and rates. And don’t even mention the newest player Tomato Lifestyle that is causing huge waves in the EV/solar system world. 

Come on Martin. You can do better than thus!
Rarely anyone is on your best buys. 

Dependent on usage and set up the best buys should generally read:
intelligent Octopus
Octopus Agile
EOn next drive v3
Tomato Energy Lifestyle 
there’s also IVO for EV owners who want to charge any time. 
anyone else reading this, join the user Facebook groups for Octopus, Eon next Drive, Tomato and Ovo. You will get much better, up to date accurate information. Warts and all.

Not forgetting that you can export your solar @ 15p on this tariff & charge car @ 7p making 8p profit, instead of just charging car for free. 👍

Agreed, I posted about this a while back as MSE's calculations are based on a Nissan Leaf charging empty to full once a week, i.e. driving around 8,000, miles a year (which is around UK average) on 2,080 kWh home charge, so anyone who does more or less will vary from the stated costs.

The Nissan Leaf is not even in the top ten of EVs currently, most are far larger and probably driven more than the UK average, given one of the main advantages is the lower cost for higher mileage drivers.

Higher mileage significantly affects the way the tariffs stack up, longer off peak charge times become a factor quite quickly as four hours at cheap rate is only enough to do something like 80-110 miles, depending on time of year, temperature and terrain.

The whole section on tariff comparison needs an overhaul in my opinion.

Hi forumites,

So... The 6% hike. How do I work out if it's going to be better off to switch or not with an EV tariff? I can get my head around how the cap affects EV tariffs....
TIA

How much electricity does your EV use each year?

How much does the rest of your household use each year? How much of that can you move into the EV hours?

With those three numbers, you can compare tariffs.

Hey QrizB,

I get that. Already on an EV tariff. But I don't get, with prices expected to rise, whether it's best to stay on my current fixed tariff, that expires later this year. Or move to one that on paper is more expensive as in the long run prices are rising...

Ie how much more expensive NOW will be cheaper in the long run?

The article linked to in the first post has now been updated.

I guess I still don't get it. Even with the updates.

The article compares to a standard non EV tariff under the price cap. It doesn't mention how to make the decision to stick or twist if you're already on an EV tariff. I know ev tariffs aren't under the price cap but it must still affect the deals available, no? 

So if I'm on a tariff today, that's fixed for x months, and there's a deal available for 2 years, say, which is ...I don't know... 5% dearer, is it worth switching? At what point does it not become worth it... 6% more, 8%, etc?

Is this not something everyone here has experience with?
