Voith Siemens Hydro/Wavegen and npower renewables on the road to
creating real power from waves
Inverness, Scotland / Heidenheim, Germany: A further important step
in the utilization of energy from the oceans has been taken by Voith
Siemens Hydro and its Scottish subsidiary Wavegen: An agreement
between npower renewables – a British subsidiary of RWE – and
Wavegen might lead to the development of a three megawatt wave
energy plant in the Hebridean island of Lewis.
The technology to be used in this plant would be based on Wavegen’s
Limpet plant on the island of Islay. This plant utilizes Oscillating
Water Column (OWC) technology and is the only grid connected OWC
plant operating under commercial conditions. The plant has been
operating since 2000.
If the project goes ahead, npower renewables and Wavegen would
integrate Wavegen’s OWC technology into a new breakwater. By
combining such a renewable energy project with the breakwater
development, civil engineering costs could be shared and result in a
considerable cost reduction for the wave power plant, while
providing local benefit from the new breakwater that creates a new
harbor for the local infrastructure. The plant is assumed to supply
electricity for around 1,500 homes per year.
“The confidence demonstrated by npower renewables in the Wavegen
technology proves our leading position in the development of wave
energy technology,” said Voith Siemens Hydro CEO Dr Hubert Lienhard.
“We believe that the operation of the Limpet plant over the last
five years gives Wavegen unrivalled experience of grid-connected
wave plant operation.”
Limpet-plant in Islay
feasibility work is concluded successfully, the project will apply
for funds from the British Department of Trade and Industry (DTI)
“Marine Renewables Deployment Fund.” This national UK based
financing mechanism aims to provide both capital and revenue
support for initial arrays of wave energy plant. A key
requirement for support under this program is that the technology
must have been demonstrated at full scale for an uninterrupted
period of at least three months. Wavegen’s five years operational
experience of the Limpet plant is unique in this regard.
Voith Hydro Wavegen Limited is a wholly owned subsidiary of Voith Hydro.
Having developed the world’s first commercial-scale wave energy
device that generates wave energy for the grid, Wavegen is a world
leader in wave energy and wave power. Voith Siemens Hydro Power
