Hello, thank you for commenting. I suggest that you try modifying the entsoe_client.py file. For example, you can download the energy data of the past 10 years (if available), and resample them on a yearly frequency. After doing that, you can generate a forecast by setting the desired forecast horizon in years. If you resample the data to have a yearly frequency, and set the forecast horizon to 9, you are going to get a forecast until 2030, as you want.
