Ouch ! Is that mainly from electric heating ? We only used ours at night but as it’s underfloor with a bit thermal mass it releases the stored heat during the day.
Well, Tempo doesn’t work for everyone and if you use €37 on all red days that’s a lot of money.
Heat pump and car charging, the latter during heures creuses.
The previous days were about €15 each, so a €22 difference. If that’s typical then I’ll just about break even compared with the base tariff. It’s a temporary thing because the living room is currently uninsulated and draughty because of the works going on (and that’s where the thermostat is). We’d expected to have the room finished by this point but we pretty much lost all of the summer and early autumn with my parents going.
Ah. OK. Charging the car HC won’t cost much more than on a normal day, but the CH will. If you run the heat pump on automatic then it’ll keep coming on during the day which is why we jut put it on during the night to ‘charge’ the floor. If it gets too cold in the evening, after putting a jumper on 
, we have a portable gas fire. It works out cheaper than using the heat pump on red days. When you get more insulation you’ll hopefully be able to keep warm in winter just using the wood burner.
It’s going to be -5 C here tonight 
which may be the coldest night we’ve had since we moved here in 2018.
I managed to spend about 3 euros on the last red day, that’s with the boiler on (just for frost protection), the fan of the insert going on all day to send the heat upstairs, and using my computer. I used gas for cooking.
Red day on New Year’s Eve is a bit crap for some people… I’m wondering if they’ll repeat what they did last year, and just do endless back to back red days until they all run out.
Yeah not very kind if you have 20 for dinner and panned and bought an oven based meal.
It was mean. Fits my theory that they are going for the money rather than trying to change people’s usage patterns now.
I think this will be my last year on Tempo. I’ll atick it out this winter then bail as soon as first red days next winter. As a low user the relatively high standing charge, especially when you add the 2 layers of taxes that get put onto it, means for the amount I use Tenpo is just not worth having to think about
It was almost exactly € 4 for me on the first red day with almost half of that used during the HC period heating the floor.
For 6KVA, the abonnement for Tempo is only € 0.36 more expensive than the Tarif Bleu base option. You may be able to get a cheaper abonnement from other suppliers but I don’t think you’ll save a whole lot.
Through lack of focus I had two or three of those last December. I hadn’t realised that red days were so punitive. Despite us being abroad from late December to early February every year (and thus missing many red days) I decided the hit from a lapse was too high and only something else to worry about. I’ve reverted to standard Tarif Bleu, I’ll look at switching to a cheaper supplier next year if it makes sense. Let EDF manage their own demand and supply issues 
We’ve a screen in the kitchen which shows our consumption in realtime so we are always careful enough, but I prefer the predictability of the standard rate.
We’ve got the app so we know the day before a red day and have a basic plan we follow on those days. For us, it’s really easy to do as were set up anyway for low consumption with around € 400 per year used. When you have a more complex setup then I expect it can be a pain.
Happy new year everyone. Inspired by the comments above, I checked our own EDF bill figures (€1k) to see what effect Tempo has had. Our bills would go up 25% if we switched back to the HC/HP Tariff bleu options, or about another €250. Not vast, but still enough to justify the now (well practiced!) routine planning and organising involved eg in cooking enough Red day meals in advance for the 2 of us. The EDF €1k figure includes our EV charging by the way.
Interesting to see the rash of articles in the French media yesterday who’ve picked up on the impact on Tempo users (900,000 households apparently) of Red day costs on NYE celebrations…
We will definitely carry on with Tempo unless/until the differential with Tarif Bleu becomes marginal/non-existent.
I looked at Hello Watt and I don’t think it can be trusted. Says the 2nd Jan is red, but EDF says it’s white.
Crikey, yes. The EDF app says white. I wonder how we find out definitively ?. Does @Badger know ?
I would trust EDF over a third-party website. Everyone has it in writing, so if they tried to charge it as a red day they’d be in trouble. 
If Hello Watt has been accurate in the past (I’m not familiar with it), then perhaps EDF took a last minute decision to switch from red to white.
I wonder if it’s a reaction to the press criticism about yesterday, with tomorrow likely to be un pont for many.
