Some tentative examples

DE/DK flows

Emulate German THE data for Denmark exports 16 July 2022 https://www.tradinghub.eu/en-gb/Publications/Transparency/Market-area-monitor

select '====', operator.operatorlabel, value, flows.directionkey, ispipeinpipe, * from flows left outer join operator on flows.pointkey = operator.pointkey and flows.directionkey = operator.directionkey and flows.operatorkey = operator.operatorkey where tsocountry = 'DE' and adjacentcountry = 'DK' and date(periodfrom)='2022-07-16' and value > 0 order by operator.operatorlabel; Output still needs to be cleaned for a duplicated directions and tsoitemidentifier (tptsoitemlabel = VIP DK-THE).

Confirm no flow through Nordstream 1 on 15 July 2022: select '======================', ispipeinpipe, operator.operatorlabel, * from flows left join operator on flows.pointkey = operator.pointkey where tsocountry = 'DE' and adjacentcountry = 'RU' and date(periodto)='2022-07-15' order by operator.operatorlabel;

Challenges

Data quality:

> 1000 GWh flow (probably erroneous data)

Give out consumption (apparently underestimation)

select left(operatorkey,2), date_trunc('month', periodto), round(sum(value)) from flows where pointkey in (select pointKey from operator where pointtype = 'Aggregated Point - Final Consumers') and flowstatus = 'Confirmed' group by left(operatorkey,2), date_trunc('month', periodto) order by left(operatorkey,2), date_trunc('month', periodto);

Sort by distribution points select pointlabel, operatorlabel, sum(value) from flows where pointkey in (select pointKey from operator where pointtype = 'Aggregated Point - Final Consumers') and periodto > '2022-07-01' and periodto <= '2022-08-01' and left(operatorkey,2) = 'DE' group by operatorlabel, pointlabel order by operatorlabel ;

German cross-border transmissions select left(operatorkey,2), date_trunc('month', periodto), round(sum(value)) from flows where pointkey in (select pointKey from operator where pointtype like 'Cross-Border Transmission IP%' and tsoCountry = 'DE' and isPipeInPipe = 'False') group by left(operatorkey,2), date_trunc('month', periodto) order by left(operatorkey,2), date_trunc('month', periodto);

Czech border transmissions as=# copy (select * from entsog_flows left outer join entsog_operator on entsog_flows.pointkey = entsog_operator.pointkey where entsog_operator.pointkey in (select pointkey from entsog_operator where adjacentcountry = 'DE' and tsocountry = 'CZ' union select entsog_operator.pointkey from entsog_operator where adjacentcountry = 'CZ' and tsocountry = 'DE') order by periodfrom desc) to '/tmp/data.csv' with CSV DELIMITER ',' HEADER;

Comments spotted: "Please note that the German dual system in VIP implementation leads to a Co-existence of Virtual Interconnection Points and Interconnection Points and may result in publication of the same physical flow at several points"
