And what is the alternative? Not consuming any power?
If the price on the exchange is that expensive, or would be, then I can't do anything about it anyway?

I would not prefer a classic annual contract with another supplier just because of winter. There I always pay the same working price, but what I (possibly) save in winter I pay extra in the other three seasons. They do make a profit, they have nothing to give away. And if they no longer make a profit, they send you the cancellation, as was seen during the crisis after the outbreak of war.

I am not aware of any potent and commercial system that intelligently charges/discharges the storage based on solar forecasts/self-consumption and day-ahead prices via Tibber/Awattar and the like.

At the moment, everything is optimized for self-consumption. If it is to become "grid-friendly," we have to sensibly use these periods of surplus and charge the storage.

Of course, you can definitely solder everything together yourself and control it via Raspberry Pis – but that's probably more for the nerds.

Basically, with variable tariffs, one always has to be aware that although the spot price has on average always been cheaper than the futures market – you can sometimes get caught out pretty badly, for example, if there is a dark lull in December and you drive your electric car to a Christmas gathering with relatives and still put the goose in the oven in the evening. The heat pump also runs at full power. You have to anticipate that and build reserves.

All-inclusive full coverage is no longer possible. That is the famous personal responsibility.

I would enjoy that and consider myself intelligent/educated enough to grasp the implications of a variable electricity tariff. But when the GME Wallstreetbets kids come along – I see that very darkly.

But how much electricity do you consume during that time? For us, it will probably amount to about 5 kWh per month, when the induction stove draws more in the evening than the storage system can supply. But otherwise, we currently don’t really need any grid electricity. With your gaming PCs and the e-car, it might look different. But as a rule, you are likely to consume the vast majority in winter. However, for the electricity supplier, you balance out in the overall calculation with people who have an even consumption throughout the year. In this respect, it might be smarter to pay “more” via a fixed price in summer and come in under the market price in winter.

That is precisely the crucial point why I am asking about experiences. The assumption that the tariff according to the market price is so expensive in winter is currently not confirmed at all. Private photovoltaic systems might be excluded then, and demand goes up due to heat pumps, but how much does that really affect the price? The wind still blows, currently more wind is in our electricity mix.

Yes, I had thought about it a lot too, but thanks to plant lamps we use so much more electricity in winter (not because of heating but for lighting) that it probably isn't worth it for me.

P.S. Currently, it is (at least for me) hardly possible to pay more than 25 cents for the "normal" electricity contract. Therefore, you really have to calculate carefully.
