Commitment to climate protection

With the connection of the offshore wind farm, 50Hertz creates important prerequisites for climate protection. The onshore and offshore high-voltage transmission grid are being expanded where new capacities are needed for the transport of electricity from renewable energy sources. 50Hertz is highly committed to this task and provides its technical know-how in the interest of the energy mix of the future and of climate protection. There is also a legal obligation to develop the grid. Since 17/12/2006, the German transmission system operators are obliged by law to create the grid connections of the planned German offshore wind farms (OWF) before their commissioning and to operate these connections afterwards.

Connection of wind farms in the Baltic Sea

The Energy Industry Act (EnWG) determines which transmission system operator is responsible for the connection of the offshore wind farms. For the Baltic Sea, this is 50Hertz. For the connection of the offshore wind farms constructed in the North Sea, the transmission system operator competent for that area is responsible.

Approval of wind farms

The Federal Maritime and Hydrographic Agency (Bundesamt für Seeschifffahrt und Hydrographie, BSH) is responsible for the approval of offshore wind turbine installations located in the Exclusive Economic Zone (EEZ). In contrast, each single federated state is responsible for the approval of installations located within the 12 nautical mile perimeter. The federated states of Mecklenburg-Western Pomerania and of Schleswig-Holstein are competent for the Baltic Sea.

The Exclusive Economic Zone (EEZ)

The Exclusive Economic Zone (EEZ) designates the area that stretches from the edge of the coastal waters to 200 nautical miles from the so-called baseline. The basis for this is international maritime law. In the Baltic Sea, the German EEZ is adjacent to the EEZs of Denmark, Sweden and Poland. Within the scope of its jurisdiction, the coastal state can build artificial islands, installations and structures such as drilling platforms and is entitled to carry out scientific marine research. In Germany, the regulations set out in the Seeanlagenverordnung (Offshore Installations Ordinance) have to be respected.
