Hello , does anybody know if it's possible to get a forecast of the dynamic prices? I would like to to create an EMS and would like to use a 48 rolling horizon window to foreacast the plan. Now i need to wait untill +- 13:30 to calculate the plan with th prices for tomorrow

probably depends on your provider integration?

i have now Nordpool and energi data service ut both dosn't have the forecast ( i guess) Only energi data service seems to have a forecast for sweden but not for all contries.

yes, for example energy zero

#

if you mean whether it's possible to get the prices for more than 24h into the future, no that's not possible

#

because the day ahead market is cleared at 12:00 and those prices become available around 13:00

#

energyzero returns:

prices:
  - timestamp: "2025-07-02 22:00:00+00:00"
    price: 0.1
  - timestamp: "2025-07-02 23:00:00+00:00"
    price: 0.1
  - timestamp: "2025-07-03 00:00:00+00:00"
    price: 0.1
  - timestamp: "2025-07-03 01:00:00+00:00"
    price: 0.1
  - timestamp: "2025-07-03 02:00:00+00:00"
    price: 0.1
  - ...

that was exactly my question. because otherwise i can only calculate my charging plan up to the next dat and when the prices are published, calculate also for the next day.

#

yes that is correct. The prices become available after a process called market clearing is done. It matches demand to supply

#

in europe, this happens for day ahead markets at 12:00

#

there are ways to forecast days into the future, but those prices are unknown until the market is actually cleared. So you could use something like machine learning to that. I know some companies who use it but it's usually not necessary
