I see the same issue. Last day with prices is Friday Feb 13th. I’ve written to entsoe support team if this is a known problem.
Works again!

Looks to me more like an additional price provider binding besides Tibber, Awattar, Entsoe, …
Data is coming from energy-charts.info stated in the attribution.
I love predictions to get an idea how future prices look like even after day-ahead. I’m every time sceptical with an AI or ML tag. In this case in general I can imagine to predict the price based on renewable shares, which are also provided by Frauenhofer Institute. Would like to have more details here but for sure this is the Intellectual Property of the provider.
I put both services in one binding because they rely on the same datasource. Normal day-ahead is available and pricing forecast if you’ve a token.
Of course it’s alpha stageand feedback is welcome!
@ weymann, I think there is a small glitch in the calculation of hourly prices at 23-24. For example, the price at 23-24 today is 7.64c/kWh in Finland (this includes the VAT and commission of the electricity provider) and Entsoe gives a value of 6.077c/kWh. I think the bug is in the calculation of the average value.
Entsoe comes with net prices without any VAT or other expenses.
I’ve following 15 minutes pricing for FI, (21:00 UTC = 23:00 FI time)
"2026-02-21T21:00:00Z": "0.07839",
"2026-02-21T21:15:00Z": "0.06279",
"2026-02-21T21:30:00Z": "0.04694",
"2026-02-21T21:45:00Z": "0.04094",
After 60 min averaging
"2026-02-21T21:00:00Z": "0.057265",
This is also reflected in my graph (22:00 DE time = 23:00 FI time)
@weymann, many thanks for checking this. I’m using a widget below:

Somewhat strange situation because all the other hourly prices are correct but not the last one (23-24). If I change “last” to “first” in row 115 then the first hour (0-1) is wrong. I don’t understand what is causing this error. The widget for today is shown below:
The bars in green show the hours when I am charging up my batteries. The price for 23-24 is 9.591c/kWh whereas it should be 9.74c/kWh so something is wrong. These prices include the VAT 25.5% and the commission of my electricity provider (0.456c/kWh). I use influxDB and in my influxdb.persist file I have a line “Dayahead_prices_Spot_Price : strategy = forecast”
EDIT: I just looked at the graph for yesterday and now it shows the correct value (7.641c/kWh) for hour 23-24. Yesterday when I made my post it showed wrong value (6.077c/kWh). Really weird.
What do you want to aggregate?
As far as I can see the widget shall only show the item state values without any aggregation.
Try oh-time-series instead of oh-aggregate-series.
OK, thanks for the tip. It seems that with oh-time-series I don’t get anything in my chart. I need to investigate my widget more carefully.
