Hi @michaelkavanagh !

I get a TypeError: missing parameter NGCBMUnitID when trying to call the B1610 API without this parameter specified. However, according to the official documentation this is not a required parameter.

Off topic:
Nice work on the wrapper! I'm trying to find a library to download Elexon data and came across your repo. I tried pywind before, but it's heavily outdated. Out of curiosity: Do you know about elexon api tool? I wonder what are the differences between your package and theirs.

Cheers!

Hi @michaelkavanagh,

it's me again. 😅 Just tried elexon v0.1.1 B1610 API with v2 parameter as you suggested in #2. There seems to be a problem with the internal result parser because the period field remains empty.

My code:

from elexon import ElexonRawClient
api = ElexonRawClient(apikey, 'v2')
generation = api.Transparency.B1610(SettlementDate = '2020-01-01', Period = '*')

generation is an array with entries like this:

{'documentType': 'Actual generation',
 'businessType': 'Production',
 'processType': 'Realised',
 'timeSeriesID': 'ELX-EMFIP-AGOG-TS-18481',
 'curveType': 'Sequential fixed size block',
 'settlementDate': datetime.datetime(2020, 1, 1, 0, 0),
 'powerSystemResourceType': 'Generation',
 'registeredResourceEICCode': '48W000000DAMC-1M',
 'marketGenerationUnitEICCode': '48W000000DAMC-1M',
 'marketGenerationBMUId': 'T_DAMC-1',
 'marketGenerationNGCBMUId': 'DAMC-1',
 'bMUnitID': 'T_DAMC-1',
 'nGCBMUnitID': 'DAMC-1',
 'activeFlag': True,
 'documentID': 'ELX-EMFIP-AGOG-22495386',
 'documentRevNum': 1,
 'Period': None}

Unfortunately, the Period field is empty for all array elements. When I do the API call via browser, I see that Period looks like this:

<Period>
<timeInterval>
<start>2020-01-01</start>
<end>2020-01-01</end>
</timeInterval>
<resolution>PT30M</resolution>
<Point>
<settlementPeriod>48</settlementPeriod>
<quantity>280.8</quantity>
</Point>
<Point>
<settlementPeriod>47</settlementPeriod>
<quantity>154.44</quantity>
</Point>
<Point>
<settlementPeriod>46</settlementPeriod>
<quantity>71.28</quantity>
</Point>
</Period>

Which makes me assume that the Period xml is not parsed properly by elexon?

Keep up the great work 😉

Hi @michaelkavanagh,

this is more of a data issue but maybe you know a solution: Is there a complete list of onshore wind units and their IDs somewhere? When downloading B1610 data, the PSR Type column says “Generation” for all entries and does not differentiate between wind / solar / gas / coal... When looking at B1420 data, I see several “Wind Onshore” units but the list is incomplete. Some units (e.g. BRYBW-1 and CRGHW-1) are classified again as “Generation”. A complete listing of onshore wind units would be very helpful. Do you know if it is available in any of the APIs?

Cheers

Although, it is possible to isntlal the package it is not usable anymore. The module can be found via pip freeze but raises a ModuleNotFoundError when trying to install. The previous version 0.2.0 still works.
