November 1 (Renewables Now) - Finnish company AW-Energy Oy announced Thursday that it had deployed its WaveRoller wave energy converter off the coast of Peniche, Portugal and commenced the commissioning work.
“I am delighted to confirm we have successfully installed WaveRoller 820 metres offshore from Peniche. At this phase of the installation, we are collecting data 24/7 to monitor the performance of the device using motion, pressure and strain gauge sensors that are engineered into its panel, foundation and bearings,” AW-Energy Oy CEO Christopher Ridgewell said.
WaveRoller, the company’s patented wave power generation device, consists of a submerged movable steel panel hinged to a concrete foundation and a power take-off (PTO) unit. The panel moves back and forth with approaching and receding waves, exploiting the naturally occurring phenomenon known as surge and feeding the PTO.
The WaveRoller already has an onshore substation in place, installed and connected to the device this past summer.
In the commissioning phase that is now taking place, the substation will be connected to the local grid, AW-Energy said. Electricity from the WaveRoller will power local homes in Peniche.
