Transmission
Norway has an open electric market, integrated with the other Nordic countries. Export and import is routine over the direct power links to Sweden, Denmark, Germany and the Netherlands. The market is handled by NASDAQ OMX Commodities Europe and Nord Pool Spot. Many of the hydroelectric plants in Norway are easily adjustable and can adapt well to variations in demand, and hence in price. On a normal day, when price is low during nighttime, Norway normally imports power, and exports during daytime when the price is higher.
West of Oslo, there is a smallsingle-phase AC power grid operated with 16.7 Hz frequency for power supply of electric railways, see Electric power supply system of railways in Norway.
