Non-retrievable production data for Italy BZs

[fr-lucas]

Dear Team,

I am struggling retrieving data for e.g. IT_NORD over November 2025 dates. While it works all fine for a number of BZs (FR, FI, RO, PL...) the italian ones do fail. With some code of this kind:

country = 'IT_NORD'
tz = 'Europe/Rome'

ts_start = pd.Timestamp('20251110')
ts_end = pd.Timestamp('20251115')

ts_tostr = lambda d : d.strftime('%Y%m%d')

client = EntsoePandasClient(api_key=f'{apiKey}')
df_response = client.query_generation(
            country,
            start=ts_start.tz_localize(tz=tz),
            end=ts_end.tz_localize(tz=tz)
        )

df_response.index = df_response.index.tz_convert('UTC')
df_response.to_csv(f'prod_{country}_{ts_tostr(ts_start)}_{ts_tostr(ts_end)}.csv', index_label='timestamp')

I then get

raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 400 Client Error: for url: https://web-api.tp.entsoe.eu/api?documentType=A75&processType=A16&in_Domain=10Y1001A1001A73I&securityToken=*&periodStart=202511092300&periodEnd=202511142300

I wonder if this issues comes from the entsoe API itself? (data missing)
I tried checking on the entsoe graphical platform but this didn't help, as some countries display empty data while I can retrieve it via entsoe-py...

If data is indeed missing, I will create a ticket towards the entsoe support team. Thank you in advance for the support!
BR, François

Given that the web API returns an error, the issue appears to originate from ENTSOE.
Note that it seems to work if you specify the psr_type (e.g., B19 for Wind Onshore).

start = pd.Timestamp("20251110", tz="UTC")
end = pd.Timestamp("20251115", tz="UTC")
df = client.query_generation("IT_NORD", start=start, end=end, psr_type="B19")

yes in that case you should contact entsoe I think

Many thanks all for both your feedbacks! I will contact them today.
And thanks for your work around the library!

I get the same issue for other countries as well. In my case for 'BE', 'IT', 'HU', 'IE'

I'm also having issues with generation per type for HU
