Portugal has taken a step towards commercial wave energy by using the technical capability of AW-Energy’s WaveRoller device to provide power and electricity for local homes.
WaveRoller is a submerged wave energy converter that uses a hinged panel attached to the seabed.
It generates electricity from the movement of the waves (surge phenomenon) and is connected directly to the electric grid onshore.
The commercially-ready unit has now been deployed and is being commissioned at Peniche, a seaside municipality in southern Portugal.
“I am delighted to confirm we have successfully installed WaveRoller 820m offshore from Peniche,” says Christopher Ridgewell, CEO of AW-Energy Oy.
“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 in to its panel, foundation and bearings.
“The data we are receiving indicates WaveRoller is operating well and performance is in accordance with our expectations.
“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 about to connect the substation to the local grid which will ensure the residents of Peniche can benefit from sustainable energy supply using wave energy.”
Ridgewell believes that the deployment in Peniche is an important step towards the commercialisation of wave energy and that it demonstrates AW-Energy’s long-term commitment to invest in wave energy technology.
AW-Energy is based in Finland and operates in multiple continents cooperating with strong industrial partners such as Lloyd's Register, Wärtsilä, Naval Group and DNV-GL.
It employs more than 100 engineers and technical staff.
