regionalnettet

Regionalnettet, or the regional electricity network, is the portion of an electric power system that sits between the high‑voltage transmission network and the local distribution networks. It covers medium‑voltage lines, substations, and switching equipment that connect regional generation and interconnections to the distribution grid. The regionalnettet is designed to transport electricity over regional distances with sufficient capacity and to provide redundancy to improve reliability.

Operations and management: The regionalnettet is operated by regional grid operators or distribution system operators under national energy regulation and European grid codes. They maintain substations, monitor power flows, and coordinate maintenance to ensure safe, reliable delivery of power within a region and to neighboring regions.

Role in the energy system: The regionalnettet enables bulk transfer of electricity from generation sources to distribution networks, supports regional balancing, and accommodates fluctuations from renewable energy sources such as wind and solar. It also provides multiple paths for power flow, helping to isolate and reroute around outages.

Regulation and context: In many countries, including Denmark, the regionalnettet is part of the broader electricity infrastructure overseen by national authorities and the system operator. The regional network integrates with the transmission grid and the distribution network, aligning with grid codes and market rules that govern reliability and cross‑border exchanges.

Modernization and outlook: Ongoing development aims to strengthen the regionalnettet through grid upgrades, digital monitoring, and enhanced interconnections with neighboring networks to improve resilience and facilitate the ongoing transition to renewable energy.
