The large production of wind power in Germany means that electricity prices can be negative throughout the country, he writes Teknisk Ukeblad.
The cable connections mean that this also affects electricity prices in Norway this weekend.
Southern Norway in particular will experience a sharp fall.
German wind power
The price will be around 19 øre / kWh from Saturday night, confirms Edgeir Vårdal Aksnes, head of the electricity company Tibber, to the website.
How long the price level will stay is impossible to say.
Many may think that it is the heavy rain in recent days that affects the price of power, but Aksnes points out that this is not the case.
– It does not turn out so fast. This time it is German wind power that strikes. Especially in southern Norway, but also in the rest of the country. This is the positive side of having cables abroad where there is a lot of wind power, he says.
