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

```python from entsoe import EntsoeRawClient import pandas as pd

client = EntsoeRawClient(api_key=)

start = pd.Timestamp('20171201', tz='Europe/Brussels') end = pd.Timestamp('20180101', tz='Europe/Brussels') countrycode = 'BE' # Belgium countrycodefrom = 'FR' # France countrycodeto = 'DELU' # Germany-Luxembourg typemarketagreementtype = 'A01' contractmarketagreementtype = 'A01' process_type = 'A51'

methods that return XML

client.querydayaheadprices(countrycode, start, end) client.querynetposition(countrycode, start, end, dayahead=True) client.queryload(countrycode, start, end) client.queryloadforecast(countrycode, start, end) client.querywindandsolarforecast(countrycode, start, end, psrtype=None) client.queryintradaywindandsolarforecast(countrycode, start, end, psrtype=None) client.querygenerationforecast(countrycode, start, end) client.querygeneration(countrycode, start, end, psrtype=None) client.querygenerationperplant(countrycode, start, end, psrtype=None) client.queryinstalledgenerationcapacity(countrycode, start, end, psrtype=None) client.queryinstalledgenerationcapacityperunit(countrycode, start, end, psrtype=None) client.querycrossborderflows(countrycodefrom, countrycodeto, start, end) client.queryscheduledexchanges(countrycodefrom, countrycodeto, start, end, dayahead=False) client.querynettransfercapacitydayahead(countrycodefrom, countrycodeto, start, end) client.querynettransfercapacityweekahead(countrycodefrom, countrycodeto, start, end) client.querynettransfercapacitymonthahead(countrycodefrom, countrycodeto, start, end) client.querynettransfercapacityyearahead(countrycodefrom, countrycodeto, start, end) client.queryintradayofferedcapacity(countrycodefrom, countrycodeto, start, end, implicit=True) client.queryofferedcapacity(countrycodefrom, countrycodeto, start, end, contractmarketagreementtype, implicit=True) client.querycontractedreserveprices(countrycode, start, end, typemarketagreementtype, psrtype=None) client.querycontractedreserveamount(countrycode, start, end, typemarketagreementtype, psrtype=None) client.queryprocuredbalancingcapacity(countrycode, start, end, processtype, typemarketagreementtype=None) client.queryaggregatewaterreservoirsandhydrostorage(country_code, start, end)

methods that return ZIP (bytes)

client.queryimbalanceprices(countrycode, start, end, psrtype=None) client.queryunavailabilityofgenerationunits(countrycode, start, end, docstatus=None, periodstartupdate=None, periodendupdate=None) client.queryunavailabilityofproductionunits(countrycode, start, end, docstatus=None, periodstartupdate=None, periodendupdate=None) client.queryunavailabilitytransmission(countrycodefrom, countrycodeto, start, end, docstatus=None, periodstartupdate=None, periodendupdate=None) client.querywithdrawnunavailabilityofgenerationunits(countrycode, start, end) ```

Dump result to file

```python xmlstring = client.querydayaheadprices(countrycode, start, end) with open('outfile.xml', 'w') as f: f.write(xmlstring)

zipbytes = client.queryunavailabilityofgenerationunits(countrycode, 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 python 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 ```python from entsoe import EntsoePandasClient import pandas as pd

client = EntsoePandasClient(api_key=)

start = pd.Timestamp('20171201', tz='Europe/Brussels') end = pd.Timestamp('20180101', tz='Europe/Brussels') countrycode = 'BE' # Belgium countrycodefrom = 'FR' # France countrycodeto = 'DELU' # Germany-Luxembourg typemarketagreementtype = 'A01' contractmarketagreementtype = "A01" process_type = 'A51'

methods that return Pandas Series

client.querydayaheadprices(countrycode, start=start, end=end) client.querynetposition(countrycode, start=start, end=end, dayahead=True) client.querycrossborderflows(countrycodefrom, countrycodeto, start=start, end=end) client.queryscheduledexchanges(countrycodefrom, countrycodeto, start=start, end=end, dayahead=False) client.querynettransfercapacitydayahead(countrycodefrom, countrycodeto, start=start, end=end) client.querynettransfercapacityweekahead(countrycodefrom, countrycodeto, start=start, end=end) client.querynettransfercapacitymonthahead(countrycodefrom, countrycodeto, start=start, end=end) client.querynettransfercapacityyearahead(countrycodefrom, countrycodeto, start=start, end=end) client.queryintradayofferedcapacity(countrycodefrom, countrycodeto, start=start, end=end, implicit=True) client.queryofferedcapacity(countrycodefrom, countrycodeto, contractmarketagreementtype, start=start, end=end, implicit=True) client.queryaggregatewaterreservoirsandhydrostorage(country_code, start=start, end=end)

methods that return Pandas DataFrames

client.queryload(countrycode, start=start, end=end) client.queryloadforecast(countrycode, start=start, end=end) client.queryloadandforecast(countrycode, start=start, end=end) client.querygenerationforecast(countrycode, start=start, end=end) client.querywindandsolarforecast(countrycode, start=start, end=end, psrtype=None) client.queryintradaywindandsolarforecast(countrycode, start=start, end=end, psrtype=None) client.querygeneration(countrycode, start=start, end=end, psrtype=None) client.querygenerationperplant(countrycode, start=start, end=end, psrtype=None, includeeic=False) client.queryinstalledgenerationcapacity(countrycode, start=start, end=end, psrtype=None) client.queryinstalledgenerationcapacityperunit(countrycode, start=start, end=end, psrtype=None) client.queryimbalanceprices(countrycode, start=start, end=end, psrtype=None) client.querycontractedreserveprices(countrycode, typemarketagreementtype, start=start, end=end, psrtype=None) client.querycontractedreserveamount(countrycode, typemarketagreementtype, start=start, end=end, psrtype=None) client.queryunavailabilityofgenerationunits(countrycode, start=start, end=end, docstatus=None, periodstartupdate=None, periodendupdate=None) client.queryunavailabilityofproductionunits(countrycode, start, end, docstatus=None, periodstartupdate=None, periodendupdate=None) client.queryunavailabilitytransmission(countrycodefrom, countrycodeto, start=start, end=end, docstatus=None, periodstartupdate=None, periodendupdate=None) client.querywithdrawnunavailabilityofgenerationunits(countrycode, start, end) client.queryphysicalcrossborderallborders(countrycode, start, end, export=True) client.querygenerationimport(countrycode, start, end) client.queryprocuredbalancingcapacity(countrycode, processtype, start=start, end=end, typemarketagreementtype=None)
