Portugal takes a step closer to commercial wave energy using the technical capability of AW-Energy’s WaveRoller® to power up electricity for local homes.

The first-of-a-kind commercially-ready offshore wave power generation device is soon to be completed thanks to the experts from Finnish-based AW-Energy – the wave energy technology developer. The team has deployed its WaveRoller® device offshore at Peniche, a seaside municipality and a city in Portugal.

“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,” says Christopher Ridgewell, CEO of AW-Energy Oy. “The data we are receiving indicates WaveRoller® is operating well and performance is in accordance with our expectations.”

Extended sea trials are being used to fine-tune the WaveRoller®’s control system to maximise its performance and yield. Engineers are also monitoring the device’s performance using the company’s next generation monitoring software which can be used to remotely access the device by any of the engineers from anywhere in the world and at any time, to help assess and manage the performance of WaveRoller®.

Ridgewell says, “The next phase of the project is injecting the power output to the Portuguese National Transmission Grid from the onshore substation. Commissioning work is already in progress with the local authorities to connect the substation to the local grid which will ensure residents of Peniche can benefit from sustainable energy supply using wave energy.”

The deployment of WaveRoller® in Peniche is an important step forward in AW-Energy’s mission to test the end-to-end commercial and technical capabilities of its latest wave energy device. It demonstrates AW-Energy’s long-term commitment to invest in wave energy technology that provides electricity out-of-phase with local wind conditions and solar that needs the sun.
