We’ve had a letter from EDF offering us “Tarif Bleu” without actually explaining what is or how it differs from the “heures creuses” we are on at the moment.
I’ve looked at their website which is pretty opaque. I’d be grateful if anyone can throw some light on this. Thanks.
It’s the colour of the air when you get your next leccy bill.
Sorry Sue, I’ve no idea really.
does this help?
We did a calculation of when we use electricity, and came to the conclusion that heures creuses/plein were going to cost us more money. So now we are on tariff bleu. The basic tariff bleu where you get a cheaper abonnement and mid-range price per KwH. Both the tempo (bleu, blanc, rouge days) and H/C were more expensive for us.
Somewhere there is a calculator that helps you determine it. But basically if you are strict about using equipment in the cheap hours, and not in the expensive hours and on red weekends then creuse/plein or tempo can work. However I can’t imagine us saying to gîte people “sorry, no more hot water/heating until tomorrow morning!”, so it doesn’t work for us.
Tarif bleu is the range of tariffs regulated by the state. They are assessed twice a year.
Private operators have other tariffs but they are not regulated and have, in the past, usually been lower that the tarif bleu. But they can change at any time without state control. Fortunately you can return to the tarif bleu (unless you are on the 18 to 36 kVA tariffs as they are no longer available on the basic tarif bleu option)
I guess if one gets an electric car, which we will sometime in the next year, all the calculations need to be redone.
will they do a battery pack for your Morgan?
I think they are developing an electric Morgan. Though since some Italian vulture capitalists bought the company it has lost its soul IMO. The new cars all have aluminium chassis, BMW engines and cost a fortune. The new breed of rich owners have nothing in common with the old oily rag brigade enthusiasts (my sort of folk) and even the UK Morgan club magazine has touched on this identity crises. Soon one will look like an old rich fart in a Morgan just as they do in Porsches (apologies to any Porsche owners ).
Tarif bleu is the collection of state regulated tarifs offered by EDF. It encompasses monophasé up to 12kVA, triphasé up tp 36kVA, Heures Creuses/Heures Pleines, & Tempo.
Crucially they all have a physical limit on what you can draw before the supply will switch off i.e. the level of abonnement. That used to be the job of the main disjoncteur de branchement but this function is now controlled by the Linky meter.
Above the kVA levels mentioned above there used to be the regulated tarif jaune which covered all low voltage (230/400V) supplies up to 240kVA, although this has now stopped & been replaced by an open market.
For supplies of 250kVA & upwards you need your own high voltage feed & local transformer, which was regulated & called tarif vert, but this has also gone to the open market.
I would assume as someone with no knowledge in this area that a vaguely modern wiring job will be suitable for these sorts of kVA, but is that actually the case @Badger?
Thanks Badger and thanks everyone else for your replies. This discussion has prompted me to go back to the letter and read it properly - I only glanced at it.
In fact it’s just a communication letter informing us as tarif bleu customers of EDF they are obliged to let us know that we can opt in or out of information about our contract that they are supplying to electricity suppliers who can then improve their marketing offers. At least I think that’s it. 
Yes, if it has been wired to NF C 15-100. The main supply conductors from the ENEDIS disjoncteur be branchement (DdB) to the main tableau must be capable of carrying the highest setting of that device, regardless of the level you pay for. This means 16mm² as a minimum for a 12kVA branchement (max. DdB setting of 60A) but in some cases only 10mm² for a 9kVA branchement (max DbB setting of 45A). These sizes increase in the event of longer runs that start to create a volt drop of over 2% from DdB to tableau.
We have monophase of 18kVA on tariff bleu, not something new customers can get. But those of us on it are allowed to keep it.
The advice from Que Choisir was to opt out and refuse data sharing.
Correct!
Why? I certainly don’t have a problem with data sharing.
We’ve a three phase 15KVa contract but just installed a Wallbox car charger that can pump out 22KVa. I suppose I should up my contract. There’s a load balancing thingy between the charger and the mainboard to prevent the charger sucking the house dry.
I like Porsche, but not so keen on Morgan - I guess it’s just a matter of taste but in times like these, think electric car owners in France must be the ones with the biggest smile right now. Hurrah to France for managing the consumer’s cost!
What was the rationale behind that?
My view is that A] I don’t have anything to hide from anybody except the details which give access to money from my bank a/c. I haven’t the least problem with EDF knowing what every amp I consume goes on what.
B] it’s important that suppliers of any service know, with access to current data, that their service is performing to spec and supplies the requirements of the customers.
I like some Porsches too, the air cooled ones preferably. A mid seventies Carrera 2.7 would do me nicely. I even flirted with the idea of selling the Morgan and buying a new Boxster Spyder about five years ago (just before I officially hit old farthood) but as I’d turned up at the showroom in my daughter’s 2002 Polo I was virtually thrown out 
. I suppose they have a lot of tyre kickers to contend with. Anyway, they saved me from myself.
Morgans are an acquired taste but they span all levels of income, These days Porsches, of any age, are IMO only for the wealthy or those that bought one before classic cars became an investment asset class.
