Dib dib. My pp was a response to robertarthur’s post. I was not thinking about problems of power generation. When one considers the implications and possibilities of this, change in water temps, I find it difficult to envisage to how one can prepare themselves for the unknowable consequences of what could happen in a comparatively short period. Bit like the weather really. It could be a blip, alternatively….. think Michael Fish, or, www.accuweather.com/en/press/57827706

Obviously never been a boy scout Nifty! It's not the change in water temp , but lack of water. Many folk think that the state will save them !

This may have been posted before or in another thread, but this seems the recommended site for seeing if you may be close to having a power cut in your area....... www.monecowatt.fr/JD

Lucky Parisians, they are, not for the first time, more equal than other French citizens: An article in the SUDOUEST:
" Une partie de la population pourrait être concernée par des délestages, mais certaines zones considérées comme critiques sont épargnées. C’est notamment le cas de Paris ou de la Corse. "

I followed the link to Enedis and found this in the FAQ section. The question was about possible compensation.
"Enedis, guarantor of the general interest, is legally bound to implement these measures of cuts located and decided by RTE. This falls into the category of exceptional events and does not give rise to compensation. If some of your electrical equipment were damaged as a result of these measures, the procedure consists in addressing your insurer, who himself will take steps towards Enedis to determine his possible responsibility."
So you pass it to your insurer, an entity dedicated to finding a way to not pay a claim, who then passes it on to another entity that is in the same frame of mind. I laughed at the very idea.

@ Aardvark, the only practical answer is to switch off electronic equipment before such a planned exceptional grid down event. When ENEDIS/RTE powers up again there is always the danger of nasty voltage spikes taking out your modern equipment, start counting. And switch them on after the grid has settled to the normal voltage. Easier: use only one, your disjoncteur de branchement. No hurry, wait ten minutes, hoping that others have absorbed the inrush currents.

Aren't there any effective gadgets for surge protection these days, RA? Specifically for 'puters, routers and the like....

I'm using one at the moment, a UPS (uninterruptible power supply) recommended by someone on a forum. From a company called APC. I did some Googling research first, decided on an affordable model and bought it from Darty. We have had a couple of short duration cuts while I was on the PC and noticed nothing apart from a little beep letting me know it was working and the lights in the room went out. I have learned to trust it. They take over in milliseconds and and keep things running long enough for you to finish what you were doing if you want to shut down. This one also protects the incoming phone line so I think the router input is safe.

@ Houpla, Surge protection with a parafoudre module at your electric frontdoor, your tableau électrique, asking voltage spikes politely: please, this way, go down to earth. A diagram.There is a parafoudre with a small footprint, it includes a protection, so the Fench call this a parafoudre auto-protégé. There are others who need help from a friend, a separate MCB / disjoncteur of 20 A, another diagram.A little health indicator ( voyant de fin vie) is also helpful in your fight against mother nature. These VDRs, also called MOVs (metal-oxide varistors) slowly degrade. Another solution, using special lightning fast avalanche zener diodes, is much better and very expensive. A picture of our unit, including a little box for the protection of the telephone/adsl line. And although they should have almost eternal life, an almost direct hit, and there they go. Going into a sort of meltdown, suddenly a very low resistance of around 40 Ω or an almost short of 0.59 Ω as can be seen here. And your main switch, seeing a short to earth, will not be very cooperative, remove defective module first. Expensive: one "fuse" goes for about € 100. Outlets with integrated surge protection are also helpful downstream, the only problem is that the nasty voltage spikes already are exploring the weaker points in your installation électrique. Better have someone at the frontdoor saying, no entry. One hundred percent security? I'm afraid not. Top

Thanks to you both for that I suspect we've got top-notch protection at tableau level as it's a relatively recent installation but I'll pass on the diagrams and UPS info to the brains of the outfit for consideration
