Hello Boubka
the majority of individuals are on subscriptions 6 or 9 kw there is very little interest to lower a slice see losing money from 6 kw to 3 kw (price of kw 0.13 euro has 3kw and 0.11 has 6kw)

for the hollow hours it is almost the same it takes 1000kw more hollow hour to start to win 1 penny


Unless miscalculating, it seems to me that for homes equipped with electric heating and having off-peak hours, there is a significant gain to achieve.

Option subscription HC: 6KW = 109,06 € / year
Option subscription HC: 9KW = 195,78 € / year
By decreasing your subscription, you win 86,72 € / year

The full rate kwh is: 0,1106 €
The kwh off-peak hours: 0,0673 €

1000 Kw transferred full price to Hc, save us:
0,1106 - 0,0673 x 1000 = 43,3€

With electric heating, it is possible to spend the morning warming stroke in HC + washing machine, dryer, dishwasher, water heater by shifting everything, and hello savings

I concede that for a basic subscription of 3 Kw, it is useless

By reporting these figures to millions of subscribers, this is a hole in the coffers of EDF

1000 Kw transferred from full price to Hc, save us:
0,1106 - 0,0673 x 1000 = 43,3 €


not quite true because subscription full time 9 kw = 124.18 euro
and 9 hollow hour subscription kw = 195.78 euro

so 195.78 - 124.18 = 71.60 euro
and 71.60-43.3 = 28.3 euro

so with just 1000kw we are still losing for 9 kw. with 6 I have not done the math but we must fall back just on its feet

after turning the greedy device at night it is demanding and in some cases not possible ...

it is very true may electric heating begins to decline seriously or even disappear, remains the pac ....

Hi people !

It's been a while since I look at the Voltalis affair. I found the opinion of the Energy Regulatory Commission. See the appendix that explains the logic of their billing principle. It's about right.

Moreover, far from me the idea of ​​wanting to defend EDF or other producer, but my little finger - who is very well informed in the present case - tells me that Voltadis are also not paragons of virtue, and that I beware of many of these birds there. It feels like the big free ad for a company and a service which, in the end, we do not know much.

I confirm the correctness of the calculations of boubka. 8)
I am one of the subscribers whose electricity consumption explodes ...
No pac, no electric heating ... Just 2 cars and an electric scooter at home ...
Simple rate subscription 9kw;
- 2008 conso less than 4000 kWh
- 2009 Consum of 6500 kWh
- conso 2010 expected 9000 kWh (projection according to current elements).

So I made the same calculations as boubka and found it difficult to amortize the extra cost of the reduced fare option ...
The bottom line is that it is very difficult to reliably obtain the essential information relating to the time slots of reduced rates ...
I even wondered if they were not determined to the mouth of the client ...
If we charge our vehicles mainly at night, the different time slots will not allow us to charge 100% at a reduced rate because the duration of certain charges will exceed the reduced rate periods ... In addition, we often charge " on the fly "a few tens of minutes or a few hours before a trip exceeding the remaining range ... We sometimes travel 90 to 110km per day.

this system is similar to load shedding circuits. I had it in an apartment. When you turned on the 4 stove plates (for example), it cut some convectors and the water heater, which limited the subscription to 32A for 4 all-electric parts.
I put a clock on the board and I was running the machines exclusively at night, at odd hours. We consumed more at night than during the day!
The system left me with a very positive impression, even though the sums involved are not huge at the individual level.

The implementation of a load shedding is simple and works, but it is far from active home automation and especially it degrades the comfort of housing.
:?
Again, the cost of 2 or three DIN rail clocks added to the electrical panel will not be amortized in one year ...

Attention, the system of load shedding is not hourly. As far as I'm concerned, I did not notice a loss of comfort.

1) A long time ago, I had an off-peak subscription (my parents actually): we did not choose the slice. Curiously, it was a slice in the day!

2) We did not know it beforehand ...

3) Without wanting to defend EdF, but there is a logic to that: they try, in a given geographic sector, to "smooth out" consumption. So they "distribute" the slots ... And it is all in all logical that they have the hand. They could make the effort to offer the niche for subscription. You take it or you don't take ... At the time, it was not done.

It must be seen that if everyone were on the same "off-peak" schedule, their line would "explode" at the time of the changeover, with all the water heaters, all the washing machines, all the storage heaters which would start. at the same time on the same sector.
