As others have stated they are effectively EVs without wheels, and an excellent way of using surplus generation overnight.

I've never had to supply evidence for any of my 'EV only' tariffs, but no idea if they do random checks (or use a database of EVSE installs?).

Batteries aren't just EVs without wheels - On an EV tariff, they expect to subsidise the cheap overnight energy through inflated daytime charges. With a battery that covers daytime usage, they don't get that. Also, not sure there's exactly a 'surplus of generation' at many times!

@rwh202 lookup the curtailment data for windfarms, and you'll see there is frequent oversupply of green energy, the issue mainly being how to get it to where the Nimbys all live. That is how come some tariffs, like octopus' agile, occasionally have negative prices during particular hh slots. Not as often as they used to though, and the peak pricing during high demand can be frightening. I personally think regional pricing makes sense too.. If you don't want wind farms, solar farms, or nuclear power stations nearby, you get to pay extra to have the electrons shipped in from someplace less picky.

Of course if you object to pylons too, you probably just get to revert to the dark ages..

I'm well aware of the curtailment data. I was just commenting that the suggestion that there was automatically surplus at night so batteries should be charged then, was a fallacy.

Last night at 02:00, it was 22.8 GW demand, with 9.9 GW from fossil and 1.2 GW from renewables. At midday it was 33.9 GW demand, but only 4.9 GW from fossil with 14.5 GW from renewables.

I agree that everything should be done to minimise curtailment and Agile pricing is one way to encourage that, but automatically assuming that using a Drive tariff to shift usage via batteries is beneficial is incorrect.

@rwh202 Yep, there is a surplus when wind blows and sun shines, the latter rarely being at night .. hence the 'smart drive' (and Intelligent Octopus) type tariffs, but when there IS a surplus, makes no odds whether it goes into cars, batteries, or boils the kettle.

@Poppy_EONNext
hi just noticed that there is now a v9 to the next drive tariff what has changed as I can’t see any difference in price or requirements to join are solar only still not able to join?
thanks ADO

Important Tariff Update: Next Drive V9 ⚡

Good Morning!

We're updating our tariff from the V8 to the Next Drive V9. Our rates will remain exactly the same as they were before. The only change is that this tariff does not come with 100% renewable energy.

• EV customers joining us from the 1st of July 2025 will receive our standard electricity.
• Existing EV customers on current contracts will continue to receive 100% renewable electricity until their contract ends.
