Hovedkraftnett

Hovedkraftnett refers to the high-voltage transmission system that carries electricity over long distances in Norway. It is the backbone of the national power grid, responsible for transporting electricity from power generation facilities, primarily hydroelectric power plants in the north and west, to major consumption centers and substations across the country. The network consists of overhead lines and underground cables operating at very high voltages, typically 300 kV and 420 kV, which minimize energy loss during transmission.

The operation and maintenance of the hovedkraftnett are the responsibility of Statnett SF, a state-owned company. Statnett ensures the stability and security of supply by managing the flow of electricity, balancing supply and demand in real-time, and investing in upgrades and expansion of the network. The grid is interconnected with the Nordic and European power grids, allowing for the import and export of electricity, which enhances reliability and optimizes energy resources. Maintaining the integrity of the hovedkraftnett is crucial for the functioning of Norwegian society and its economy, impacting industries, businesses, and households alike.
