Wind and Wave in One

Poseidon is a concept for a floating power plant that transforms wave energy into electricity. The power plant furthermore serves as a floating foundation for offshore windmills, thus creating a sustainable energy hybrid. A 37 meter offshore demonstration plant was launched in the summer of 2008. A full scale Poseidon plant can measure from 100 and up to 420 meters depending on wave and wind conditions at the chosen location.

A Poseidon 230 meter scale plant is expected to perform as follows:

• Efficiency of transforming inherent wave energy to electricity of 35%
• The total installed effect of the plant is 20 MW, including the 3 windmills
• Energy yield from the waves of 28 GWH per year provided the plant is located in the Portuguese part of the Atlantic Ocean
• Energy yield from the 3 windmills of totally 22 GWH per year
