Hi Any plans to add dynamic tarifs to DESS? In Denmark the tarifs vary during the day. It does not make sense to use DESS with fixed tarif - at least in Denmark :slight_smile: Martin

I have read the manual and can see that DESS supports dynamic spot prices. But in Denmark, we have tariffs that vary over the day. 00:00–06:00 - €0.019 06:00–17:00 - €0.058 17:00–21:00 - €0.173 21:00–24:00 - €0.058 So our tariff is not a fixed factor that I can add to the spot price, but it va…

From the manual: Blockquote Then, you can fill out the price per hour (more granularity is currently not possible).

I assume kent2ben means that they have a variable grid fee in addition to the variable spot price. This is not currently supported by DESS as you are not able to make a formula with time variability for dynamic pricing.

Poland same thing, the grid fee varies depending if it’s night or weekend even with dynamic pricing however usually the lower grid fees coincide with the lower P anyway but not always (from 00h to 06h)

I have same problem also in Denmark. For know DESS is really not usable for us. Could be nice to have an option to make multiple formulars, depending on the time of the day. Here we have a vinter tarif (Fixed transport price) like Kent2ben says 00:00–06:00 - €0.019 06:00–17:00 - €0.058 17:00–21…

I think Victron needs to take another look at this. It needs a time and day of the week flexible factor in the price formula. Actually, this shouldn’t be such a big problem. But I’m a bit surprised that no one from Victron is commenting on this at the moment.

Perhaps I don’t understand. But if these 4 prices are the same every day, you can put it in DESS like this: [image]

Hi The “buy prices” are set on an hourly basis and fluctuate every hour, day, week… So the buy prices are not the same every day. Only the tarifs or fees are the same every day. So if I can set the fees in the screenshot that @Ton_Gans shows and it gets added to the price it would be perfect. M…

This applies to fixed prices and is good and right. However, we are talking about dynamic day-ahead prices in connection with different network fees at different times
