Tidal energy: The first commercial-scale WaveRoller unit is completed

The Final Assembly of the First commercial-scale 350 kW WaveRoller unit has been completed in Peniche, Portugal.

Upon deployment the unit is submerged to the sea bed and connected to the National Electricity Grid for production of electricity from the ocean waves.

The WaveRoller is a device that converts ocean wave energy to electricity. The machine operates in near-shore areas (approximately 0.3-2 km from the shore) at depths of between 8 and 20 meters. Depending on tidal conditions it is mostly or fully submerged and anchored to the seabed. A single WaveRoller unit (one panel and PTO combination) is rated at between 350kW and 1000kW, with a capacity factor of 25-50% depending on wave conditions at the project site. The technology can be deployed as single units or in farms.
