Contents

EDS (Energinet, Danish TSO) — DK1 (West) and DK2 (East)

File	Description	Coverage
eds_dayaheadprices_dk1/dk2.parquet	Day-ahead spot prices (current dataset)	~2025-09-30 → present
eds_elspotprices_dk1/dk2.parquet	Day-ahead spot prices (legacy dataset, longer history)	2000-01-01 → 2025-09-30
eds_productionconsumptionsettlement_dk1/dk2.parquet	Actual generation by source and consumption	~2004-12-31 → present
eds_datahubpricelist.parquet	Nettariffer (every net company's grid tariff), Energinet's own system/transmission tariffs, elafgift (electricity tax), and subscription fees — the full DatahubPricelist price-component list, all charge owners, not split by DK1/DK2 (GLN_Number identifies the charge owner)	2014-01-01 → 2027-03-31 (includes announced future tariffs)

ENTSO-E — DK1/DK2 direct (complements the EDS files above)

File	Description
entsoe_dk1/dk2_load_actual.parquet	Actual (realised) total system load, MW
entsoe_dk1/dk2_load_forecast.parquet	Day-ahead forecast total system load, MW
entsoe_dk1/dk2_windsolar_forecast.parquet	Day-ahead wind+solar generation forecast (only ~1 day ahead, archived history)
entsoe_dk1/dk2_installed_capacity.parquet	Installed generation capacity per type, yearly snapshots

Interconnector data (Denmark's actual physical borders)

File pattern	Pairs covered
entsoe_flow_{pair}.parquet	Actual physical cross-border flow (MW), both directions
entsoe_ntc_{pair}.parquet	Day-ahead estimated Net Transfer Capacity (MW), both directions — sparse/empty for pure Nordic-Nordic borders (dk1_no2, dk1_se3, dk2_se4), which use flow-based (JAO) capacity allocation instead

Pairs: dk1_delu, dk1_no2, dk1_se3, dk1_nl, dk2_delu, dk2_se4.

Note on eds_datahubpricelist.parquet

Columns include ChargeOwner, GLN_Number, ChargeType (D01 subscription, D02 fee, D03 tariff), Note/Description, ValidFrom/ValidTo, VATClass, Price1–Price24 (hourly for ResolutionDuration=PT1H tariffs, single monthly/yearly value otherwise), and ResolutionDuration. To reconstruct "nettarif C" for a specific net company, filter ChargeType == "D03" and Note == "Nettarif C" for that company's GLN_Number; Energinet's own system/transmission tariffs and elafgift are under GLN_Number = "5790000432752".

Note on Nordic flow-based congestion data

JAO's Nordic flow-based market coupling data (PTDF/shadow-price congestion data) is not included here or anywhere in this collection — JAO's terms of use prohibit redistribution without prior written authorization. If you want it, register for a free personal token at publicationtool.jao.eu.
