kraftnett

Kraftnett is the high‑voltage electricity transmission network that forms the backbone of a country’s power system. It transports electricity from power plants to distribution networks and large industrial consumers, and it interconnects with neighboring countries to enable imports and exports. The kraftnett comprises transmission lines, substations, switching equipment, and cross-border interconnections, and is controlled and coordinated by a transmission system operator (TSO). Its primary functions include delivering power over long distances, maintaining system reliability, and balancing supply and demand in real time. The grid operates under national regulations and participates in broader European grid operation and electricity markets.

In Norway, the kraftnett is operated by the national TSO, Statnett, which maintains and develops the transmission network at high voltages to ensure secure and efficient power delivery. The network connects hydro, wind, and other generation sources to distribution grids and to international interconnections with neighboring countries. The voltage levels typically include high‑voltage corridors above 132 kV, with HVDC links used to facilitate large cross-border transfers when needed. The operation of the kraftnett is coordinated with market mechanisms and cross-border trading through European and regional bodies.

Regulation and governance involve national authorities that license and oversee transmission operators, set tariffs, and ensure grid reliability. In addition, European grid codes and market platforms support cross-border coordination and electricity trading. As energy systems evolve with more renewable generation and electrification, the kraftnett faces ongoing modernization challenges, including capacity expansion, resilience to weather events, cybersecurity, and the integration of new technologies to support a flexible and decarbonized energy system.
