Tibber, Pulse Smart Home Module experiences?

Quite expensive for a summer day – does that already include the costs for Tibber?

Gross including taxes/fees. Without them, the price is exactly 0 cents.

And the much more interesting question is how it looks in winter when a) electricity production during the day is completely different and b) you can’t fill the storage.

a) The standard load curve always looks like this. Peaks in the morning and evening, a dip at midday. Differences usually lie in the variance.
b) I don’t understand that point.

Quite expensive for a summer day – are the costs for Tibber included in that? And the much more interesting question is how it looks in winter when a) the power production during the day is completely different and b) you don’t manage to fully charge the storage.

The fees should be included. Tibber doesn’t choose the prices; they are based on the electricity exchange. Maybe it’s cloudy in many places today, no idea. On Sunday, the price in the afternoon was, as often cited, -46ct. In the overview, the winters don’t look so different at all. I assume negative prices then disappear, but fluctuations during the day that you can take advantage of also exist in winter. If you don’t fully charge the storage via photovoltaics, it makes sense, as sysrun says, to fully charge the storage from the grid at the cheapest time of day so that you don’t have to pay the daily peak in the evening.

Well, what do you do when you are standing at the gas station with an empty tank? Wait for a free gas can to fall from the sky or fill up as much as you need?

What matters is what you do with the mass. There are consumers that you can easily push and that really consume a lot. By the way, if you have pushed those before, not only the wallet benefits but also the entire network.

If I want to have the house warm at -20 degrees and roast a goose in the oven, I will do it anyway.

a) The standard load curve always looks like this. Peaks in the morning and evening, a dip at noon. Differences usually exist only in the magnitude.

That is clear to me. Just at what level, when cheap photovoltaic electricity is not in the grid during winter. Then do you have to pay 30 cents at noon and 45 cents in the evening/night? Then you can draw "expensive" electricity from the grid at noon (your own photovoltaic system doesn't supply), so you don't have to consume even more expensive electricity in the evening. That is what I meant by "not getting the storage full."

If you can't fully charge the battery with the photovoltaic system, it makes sense, as sysrun says, to fully charge the battery from the grid at the cheapest time of day so that you don't have to pay the daily peak in the evening.

Especially in winter, the batteries are rather dead capital. I'm curious to see what I can program for it anyway.

Then you can "buy" expensive electricity from the grid at noon (your own photovoltaic system does not supply), so that you don't have to use even more expensive electricity in the evening. That’s what I meant by "not getting the storage full".

I don't have a crystal ball. No one knows how things will develop in the coming years with more heat pumps & e-cars and more renewables. Fixed contracts are great, no question. But they only work in one direction. Recently, I heard a question whether electricity providers should be required by law to pass on the reduced costs. No, of course not – you signed for a fixed price. It’s like mortgage interest rates – a bet on the future.

With flexible contracts, at least I have a chance to steer something. Besides, I don’t give interest-free loans to the suppliers (advance payments), but pay the consumption every month.
