Offshore wind

Located 85 km north of the Dutch coast, Gemini harnesses the North Sea's strong and consistent winds.

This illustration maps wind speeds in the North Sea. As expected, wind speed increases with distance from shore. The countervailing factor is the length of the export cables needed to convey the energy from the wind park onshore.

Gemini's sweet spot lies where winds average 10.2 to 10.4 m/s.

68 square kilometres

To get an idea of the size of Gemini, we have made a drawing of
the wind park on a map of the Amsterdam city centre.

Full overview

This is the whole of the Gemini design in a single view. Two sub-parks, two offshore high voltage stations, two export cables and one land high voltage station.
