Overføringsledningene

Overføringsledningene refers to the power transmission lines in Norwegian, specifically those that carry electrical power from the power grid to the consumer. The term is derived from the Norwegian words "overføre," meaning to transmit, and "ledning," meaning wire or cable. This infrastructure plays a crucial role in ensuring a reliable and efficient supply of electricity to households and businesses across Norway.

The overføringsledningene is operated by regional power companies, also known as distribusjonsselskapene, which are responsible for maintaining and upgrading the power transmission infrastructure. The companies invest heavily in modernizing the grid to meet increasing power demand and incorporating newer technologies. The main goal is to provide high reliability and low losses during transmission.

Overføringsledningene in Norway consist of high-voltage overhead transmission lines, underground cables, and distribution networks. The lines range from 10 to 420 kV and are either doubles, as in pairs, or open. Reclosing substations are often used to manage power shifting. The companies make significant investments in research and development to improve the efficiency and reliability of the power transmission network.

Customers of the overføringsledningene are widespread and can vary in scale from large industrial users to household ratepayers. Each distribusjonsselskap has its goal aligned with Norwegian grid operations that demand certain standards and quality, facilitating productivity and reliability within the power industry. The overføringsledningene must work in unison with other power transmission systems, such as the interconnected Nordic electricity market. Regular maintenance schedules and continuous upgrade ensure that services offered to users meet their demand.
