Adding more Economy 7 sockets

[westie101]

Don't forget that Jersey is not connected to the UK grid, but the French grid as well as having local generation! At present of the of the 51.5GW demand in France 91.4% is nuclear generation

Two-rate tariff, most often used with traditional wet radiator or approved underfloor heating systems.
Offers 20 hours of discounted electricity for approved space and water heating, providing central heating and hot water when you need it.
All other appliances run on General Power and Lighting Rate at all times.
Economy 20 (Rate 2) 10.22p* a unit (9.73p)

20 hours discounted electricity in any 24 hours for approved space and water heating*.
Remaining four hours in any 24 will be an interruption to your space and water heating timed at our discretion.
No interruption will be more than two and a half hours at any one time.
General Power and Lighting (Rate 1) 14.50p* a unit (13.81p)

For all units used during any 24 hours on all appliances other than approved space and water heating run on Economy 20.

*Certain types of heating equipment may not be suitable for connection to this tariff. We are happy to advise.

Humm It sounds a bit like the old days of different rates for 5A and 15A circuits ! (i'm too young though)

Sounds like they will connect the heating and water to the cheaper rate.

Sockets and lights on the other, which is available 24hrs a day

Is that correct ?

I guess the advantage to them is that they can turn off the heaters at peak cooking/grid times ?

That may explain why the electricity is 'generally cheap', but I still don't think that excuses them for having a 'standard rate' which applies to only 4 hours of the day, thereby enabling them to say that they are supplying 'cheap rate electricity' for 20 of the 24 hours in a day

Google, as always, is your friend!!!!!

Not just Google - that link was in my post!

Come on John. Don't get bogged down.


There isn't much difference in the tariffs really ?

I thought E7 was 20p / 60p or is my memory wrong ?

 

[westie101]

The Economy 7 tariff details include two energy rates; the day time rate, usually costing between 13p and 17p per unit used (measured in KWHs), and the cheaper night time rate usually costing between 7p and 10p.

A standard, non-Economy 7, tariff will charge a flat rate of between 12p and 17p per KWH.

IIRC, my last bill was on the basis of 6.1p / 15.4p per kWh (excl VAT).

I thought we encouraged people who were on E7 but no longer had storage heaters to get off E7 as the day time rate was significantly higher than non E7

In general, we do, since, as you imply, it would usually be in their financial interest.

In my case, the 'break-even point is around 33%-34% of electricity used off-peak. Since (a) I am fairly nocturnal, (b) I have quite a lot of equipment running 24/7 and (c) given the late timings of my E7, I can make good use of 'cheap electricity' (for dyers etc.) in the mornings (up to about 9:30), I usually manage 40-45% - so, for me, E7 represents a significant saving, despite the absence of storage heaters. However, I'm sure that's fairly exceptional, and that most people without storage heaters would be better off without E7.

Generally if folk can run washers, dryers & dishwashers overnight as well as water heating (even if they have gas) they will save over using a single rate tarriff.
Also this time of year if the off-peak is still running at 07:30 GMT, that equates to 08:30 BST so any electric showers will be on the lower rate!

As I said, with my E7 tariff, one needs to use more than 33-34% on 'cheap rate' in order for there to be a cost-saving. I doubt that many people would achieve that, even though I do.

Also this time of year if the off-peak is still running at 07:30 GMT, that equates to 08:30 BST so any electric showers will be on the lower rate!

True - even better for me, thanks to whoever set up the clock for 08:30 GMT (aka 09:30 at the moment!). As I said, we generally run our dryer in that last hour or two of cheap electricity in the morning, since I'm not real fan of dryers running whilst I'm asleep!

I was also under the impression that the whole house switched to E7 but since my kind electricity supplier sent me one of those usage monitor gadgets (the ones with the ferrite thingy clamped round the cable) it doesn't appear to be the case! I say this because it's clamped round only one cable (from the day meter) and it still registers a power draw at night.

It would do - all the circuits on that are still live - how could they not be? Would you really want it so that only the storage heaters got electricity at night? No lighting, no TV, no kettle, no opening the fridge or feezer, no burglar alarm etc after 11pm?

I believe the OP was saying that he thought that, somehow, the entire installation switched to the 'night meter' at night, so that he would not expect the power taken by the sort of loads you mentioned to be going through 'the day meter' at night. He is indicating that, contrary to his expectations, all those loads are being charged at 'day rate', even during the night.

Did he think that, somehow, all his non-heating circuits got moved to the night CU, and back again twice every 24 hours?

I doubt it, but he may well have thought that the supply to the 'day CU' was switched such that it was got power from the 'night meter' during low-cost periods.
