From October 15, 2022 to April 15, 2023, water heaters in households subject to an off-peak subscription between 12 p.m. and 2 p.m. will no longer be switched on automatically. The savings could be significant according to Enedis.
Announced by a decree published on September 27, Enedis confirms the request made by the network operator RTE. Between October 15, 2022 and April 15, 2023, Enedis will cut off the automatic triggering of hot water tanks for around 4.3 million people.
« This is a request from the State and RTE to smooth consumption, by shifting the meridian peaks towards the night »specifies Thierry Sudret, director of operations and systems at Enedis.
This measure concerns households equipped with a Linky meter, subscribers to the off-peak tariff between 12 p.m. and 2 p.m., with a power less than or equal to 36kVA.
« The measurement is transparent for customers, the price remains the same as the consumption and the bill », says Thierry Sudret. Each household can still manually activate its hot water tank and in this case will pay the off-peak rate as provided for in its contract.
« The device may seem trivial but is formidable in terms of efficiency, the hot water tank is the second item of electricity consumption after the heating », justifies Enedis. Between 1 and 2 gigawatts could thus be saved, the equivalent of two nuclear units.
This measure will be applied remotely via a signal transmitted to the counter. The households concerned will be notified by their access provider.
