A next-generation wave energy conversion (WEC) device being developed by Finland’s AW-Energy is set to start powering homes in the Portuguese surfer town of Peniche, with commissioning complete and switch-on of its connection to the national grid said to be “imminent”.

The WaveRoller, a now “commercially ready” version of a concept that has been in testing since 2009, is a 3MW WEC that delivers a “continuous” 350kW production output.
