DatasetsSurplus/deficit, cumulative - real-time data

Information is based on the real-time measurements in Fingrid's power control system. Power deficit/surplus represents the balance between production and consumption in Finland, taking into account imports and exports. It is calculated as the difference between the measured net import/export and the confirmed net exchange program between Finland and the other Nordic countries. The cumulative production deficit/surplus is the hourly energy generated from the difference. Sign convention: production deficit -, surplus +. The data is updated every 3 minutes.
