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
