Übertragungsnetzbetreibern

Übertragungsnetzbetreibern, often abbreviated as ÜNB, are crucial entities within the energy sector responsible for operating and maintaining the high-voltage electricity transmission grid. These networks are the backbone of a country's electrical system, transporting electricity generated from power plants over long distances to regional distribution networks and ultimately to consumers. ÜNBs ensure the stable and reliable flow of electricity, managing supply and demand in real-time to prevent blackouts.

Their responsibilities extend beyond mere operation. ÜNBs are also tasked with planning, expanding, and modernizing the transmission infrastructure to accommodate the increasing integration of renewable energy sources, such as wind and solar power, which are often located in remote areas. They play a vital role in ensuring the security of supply, managing cross-border electricity flows, and facilitating a functioning energy market. In many European countries, these operators are organized independently from electricity generation and supply companies to guarantee fair access to the grid for all market participants. Their work is heavily regulated by national authorities to uphold public interest and energy security.
