Off-Peak Electricity Tarrifs

kamir

Are there any energy suppliers offering off peak electricity tarrifs ? All the Economy 10 deals seem to have been removed, the only company i can find is Octopus.

Is there a specific reason why you are asking about Economy 10? That's an obsolete tariff that's only generally offered to people with legacy E10 meters.

Every supplier has at least one Economy 7 tariff.

Some suppliers (not limited to Octopus, although they are the most commonly named example) have other "innovative" multi-rate tariffs that generally require a functioning smart meter.

E10 in my region gives 10 hours split into 3 bands - E7 gives 7 hrs continuosly overnight

But assuming you really mean economy 10.

Economy 10 is a legacy multirate tariff - most of the new suppliers never supported it - and the big 6 - many only generally support it for their own legacy customers.

And even that seems to be changing. 

Even around 5+ years ago when I was first put on E10 - as EOn abandoned radio switched heatwise - I phoned around - and only 1 other was willing to quote me E10 / in my region - and they said couldn't when tried again around 18m later.

There used to be some firms that would bill you on E7 on an E10 meter too - but that often meant they would swap you to standard E7 meter and timings in the even the meter was replaced - for age or fault etc. 

And it seems others have done this - seen posts about Ovo and worryingly EOnNext - doing this.

EDF still publish their regional E10 tariffs openly - as other legacy like E20:20 - but that doesn't mean they offer it to new customers.

There was one recent post where the user was trying to get around Ovo shifting them from E10 to an E7 meter.

See the thread around this post - about trying to contact EDF's complex metering team

"You have to phone EDF complex meter team who started the switch there and then . The smart meter can be controlled by the supplier to switch to Eco 7 with a 3 hour afternoon boost "

But note that was reference to an event a few years ago

The second post by  @JameelU  "may"  have implied he was getting somewhere with EDF.

Unfortunately the OP didn't come back after the 1-2 week wait in his second post AFAIK to report success or failure.

Found this list of potential suppliers on a quick google - but the article is last year - and no idea how accurate it was then or now.

PS Are you saying Octopus actually support E10 - in the past I have read that it doesn't - only E7 - but never checked direct with their customer services ?

And most if not all of the other suppliers also support E7.

Unless you have a BEV of plug in hybrid(*) - you are I suspect looking at E7 if not already on multirate

Some typical pricing - from EDF - who offer higher peak / off-peak splits than some others - can be seen here. But check your region / your prefered supplier.

Looks possible - but I'd do your sums carefully - including the efficiency of battery charging and invertors ( a quick google says maybe 10-20% loss).

I am guessing even at todays rates - the payback period can become non trivial.

Especially if get the battery sizing too low for your daily use (TDCV is around 8kWh) or charging system out of phase with off-peak tariff.

You might however might be better looking through some of the many discussions on home battery storage under the money saving forum rather than energy

Either search the forum - threads like say

came up near top of search - it is under another section

Some EV tariffs can give low off peak rates cf even E7 - say 10p off-peak.

Some insist you have a BEV (the intelligence is in the car etc) - others ? - but these are normally for a shorter time - but having said that some also give a full 6 hours fixed off peak.

They did a work around, if my memory serves me correct it involved paying 2 standing charges.

The off-peak rate of Economy 10 is higher than Economy 7, because there are more hours of it.  Conversely the peak rate is lower than E7, but charging a battery on E10 would be more expensive than E7 (hypothetically, if you could even get onto E10 which I seriously doubt possible).

Or there's Cosy Octopus if you have a heat pump, best of both worlds in a way with 6hrs off-peak and 3hrs peak, and the rest at standard rate. 
Or Flux for solar, but only 3hrs at cheap rate.  This one has variable export rates too, in the different off-peak/standard/peak periods.
