Comatec’s Energy Efficient Motion Control centre has been involved in the development of AW-Energy Oy’s WaveRoller technology. AW-Energy Oy’s owners include Fortum and Sitra. WaveRoller is a wave power plant that operates on the sea bed, near the shore. The back and forth motion of the waves moves a panel connected to a power generating system, which is hinged at the bottom. A generator in the device creates electricity, which is then fed along a cable to the shore.
