alpha ventus

In May 2009, TenneT realised the first grid connection at sea in Germany with alpha ventus. This grid connection marks the beginning of the era of offshore wind energy, because with alpha ventus, energy generated at sea could be fed into the German power grid for the first time.

About the project

66 kilometers long and 62 megawatts strong AC link

alpha ventus

The "alpha ventus" wind farm of the same name was established as a test field around 45 kilometres off the coast of Borkum in 2006 to test and research the generation of wind energy at sea. Due to its proximity to the mainland and its low output of 62 megawatts (MW), alpha ventus was connected to the transmission grid using three-phase current technology. The 66 kilometre cable runs from the sea via the island of Norderney ashore and from there to the Hagermarsch transformer station. There, 110 kilovolts of the energy generated at sea is fed into the power grid.

Connecting concept

Due to the proximity to the mainland and the installed transmission capacity, the grid connection system was realised as a technically and economically efficient three-phase alternating current (AC) connection. The wind farm is directly connected to a coastal substation via subsea cable and a short underground cable on the mainland. Here, the green energy is directly fed into the respective voltage level.
