@Chriscutler They want to turn off water heaters in the afternoon (when they should be off anyway). Notice (min 1 week) will be given to affected customers and it should only affect those whose water heaters (and we are only talking about accumulateurs which are separately switched on the consumer board on an overnight setting) aren’t working properly or have been manually switched to run all day long. With a week notice, customers with a special requirement should have time to contact EDF and discuss it with them. Sorry, as someone whose water heater is just like this and is on auto, I’m not worried. There will be no cold showers! France is taking preemptive action to avoid electricity supply problems. I’m okay with that. Openly discussed, planned protection for consumers and the information is openly available. I prefer that to power cuts.
