Electricity available to the internal market (monthly)

Monthly electricity available to the internal market in gigawatt-hours, for EU member states, EFTA countries, EU candidates and EU/euro-area aggregates. Eurostat dataset nrg_cb_eim ('Electricity available to internal market'), filtered to freq=M and unit=GWH ('Gigawatt-hour'). Each row is one (month, country). The series tracks electricity actually available on the market - it pairs with the generation-side monthly data (the Ember electricity-generation dataset) to contrast what is generated with what the market can draw on. Method: Eurostat compiles monthly energy statistics transmitted by the member states; non-EU/EFTA/candidate countries are dropped (same licensing rule as the other Eurostat datasets). Units: gigawatt-hours (GWh). Caveats: the series is not seasonally adjusted, so the strong heating/cooling seasonality (e.g. FRA 2025-01 = 45,473 GWh vs 2025-06 = 29,746 GWh) must be read against the same month of earlier years; recent months are provisional and revised; the UK and Kosovo (XK) are dropped by the connector's commercial-use geo rule; the EU27_2020, EA21, EA20 and EA19 aggregates are included as published. Coverage: ~40 geographic units after the geo rule, 2008-01 to the present, monthly.

Join keys: country_code (ISO 3166-1 alpha-3), month. Cadence: refreshed monthly; Eurostat updates the table with roughly a two-month lag. Sample use: filter country_code='DEU' to track Germany's monthly electricity supply.
