Hydrological data

Each week, the NVE prepares an overview of the water levels in each reservoir in Norway. Aggregated data per spot market area and for the country as a whole are normally released on Wednesday afternoons. The available history for this data series extends as far back as 1993. As regards the individual spot market areas, the statistics are available within the timeframe of the area division in question.

The water levels vary over the course of the year, peaking in late autumn and with the lowest levels in April/May. If all the reservoirs had been 100% full, this would correspond to 82 TWh.

The reservoir statistics are prepared by the NVE and are published each Wednesday at 13.00 hours, check their website.
