The electricity grid
The electricity grid forms the very backbone of the power system.

Health, safety and the environment are at the core of all our activities.
The main grid
Statnett is responsible for the main grid, which makes up the «highways» of the Norwegian electricity supply. The main grid is made up of 11 000 kilometres of high-voltage power lines, interconnectors and 140 substations throughout the country. Operations are monitored by one national and three regional dispatch centres.
