Error when running query_scheduled_exchanges for AT-HU Total Commercial Schedules

See original GitHub issue


I’m using query_scheduled_exchanges to download the Total Commercial Schedules between pairs of BiddingZones. For most pairs it works OK, but for the Austria-Hungary exchange (AT_HU, and the opposite direction), I’m getting an error:

ValueError: Length mismatch: Expected axis has 24 elements, new values have 93 elements

When I accessed data for this pair through the web interface, I noticed the data is given in 15minutes intervals, so maybe this error is connected with this representation. However, for some other pairs with 15 minutes data, like DE-LU_BE, query_scheduled_exchanges works fine.

I run the entsoe-py on WinPython (WPy64-4741) with Pandas 1.1.5.

Any help to resolve that issue will be much appreciated.

Code to reproduce the error:

from entsoe import EntsoePandasClient
import pandas as pd

client = EntsoePandasClient(api_key="xxx")

start = pd.Timestamp('20201101', tz='UTC')
end = pd.Timestamp('20201102', tz='UTC')

totATHU = client.query_scheduled_exchanges('AT', 'HU', start=start, end=end)

Hi, It seems to be a similar problem as the one mentioned in #97, the issue occurs when duplicates are found in the xml returned by ENTSOE. A simple workaround is proposed in commit #101.

Ah I see, thanks for the quick reply 😃 I’ll let you know if the fix works once the PR is merged!
