Python client for the ENTSO-E API (european network of transmission system operators for electricity)

entsoe-py

Python client for the ENTSO-E API (european network of transmission system operators for electricity)

Documentation of the API found on https://transparency.entsoe.eu/content/static_content/Static%20content/web%20api/Guide.html

Installation

python3 -m pip install entsoe-py

Usage

The package comes with 2 clients:

• EntsoeRawClient: Returns data in its raw format, usually XML or a ZIP-file containing XML's
• EntsoePandasClient: Returns data parsed as a Pandas Series or DataFrame

EntsoeRawClient

from entsoe import EntsoeRawClient
import pandas as pd

client = EntsoeRawClient(api_key=<YOUR API KEY>)

start = pd.Timestamp('20171201', tz='Europe/Brussels')
end = pd.Timestamp('20180101', tz='Europe/Brussels')
country_code = 'BE'  # Belgium
country_code_from = 'FR'  # France
country_code_to = 'DE_LU' # Germany-Luxembourg
type_marketagreement_type = 'A01'
contract_marketagreement_type = 'A01'

# methods that return XML
client.query_day_ahead_prices(country_code, start, end)
client.query_net_position(country_code, start, end, dayahead=True)
client.query_load(country_code, start, end)
client.query_load_forecast(country_code, start, end)
client.query_wind_and_solar_forecast(country_code, start, end, psr_type=None)
client.query_generation_forecast(country_code, start, end)
client.query_generation(country_code, start, end, psr_type=None)

client.query_net_transfer_capacity_monthahead(country_code_from, country_code_to, start, end)
client.query_net_transfer_capacity_yearahead(country_code_from, country_code_to, start, end)
client.query_intraday_offered_capacity(country_code_from, country_code_to, start, end, implicit=True)
client.query_offered_capacity(country_code_from, country_code_to, start, end, contract_marketagreement_type, implicit=True)
client.query_contracted_reserve_prices(country_code, start, end, type_marketagreement_type, psr_type=None)
client.query_contracted_reserve_amount(country_code, start, end, type_marketagreement_type, psr_type=None)
client.query_procured_balancing_capacity(country_code, start, end, process_type, type_marketagreement_type=None)
client.query_aggregate_water_reservoirs_and_hydro_storage(country_code, start, end)

# methods that return ZIP (bytes)
client.query_imbalance_prices(country_code, start, end, psr_type=None)
client.query_unavailability_of_generation_units(country_code, start, end, docstatus=None, periodstartupdate=None, periodendupdate=None)
client.query_unavailability_of_production_units(country_code, start, end, docstatus=None, periodstartupdate=None, periodendupdate=None)
client.query_unavailability_transmission(country_code_from, country_code_to, start, end, docstatus=None, periodstartupdate=None, periodendupdate=None)
client.query_withdrawn_unavailability_of_generation_units(country_code, start, end)

Dump result to file

xml_string = client.query_day_ahead_prices(country_code, start, end)
with open('outfile.xml', 'w') as f:
    f.write(xml_string)

zip_bytes = client.query_unavailability_of_generation_units(country_code, start, end)
with open('outfile.zip', 'wb') as f:
    f.write(zip_bytes)

Making another request

Is the API-call you want not in the list, you can lookup the parameters yourself in the API documentation

params = {
    'documentType': 'A44',
    'in_Domain': '10YBE----------2',
    'out_Domain': '10YBE----------2'
}
response = client._base_request(params=params, start=start, end=end)
print(response.text)

EntsoePandasClient

The Pandas Client works similar to the Raw Client, with extras:

• Time periods that span more than 1 year are automatically dealt with
• Requests of large numbers of files are split over multiple API calls

Please note that this client requires you to specifically set a start= and end= parameter which should be a pandas timestamp with timezone. If not it will throw an exception

Mappings

These lists are always evolving, so let us know if something's inaccurate!

All mappings can be found in mappings.py here

For bidding zone that have changed (splitted/merged) some codes are only valid for certain times. The below table shows these cases.
