Ocean Power Technologies
The relative motion between the two 
parts of the machine is used in a hydrau-
lic PTO to generate electricity. 
OPT has also developed an Underwater 
Substation Pod (USP) that can aggregate 
electrical output from ten Power Buoys 
into a single transmission cable. 
OPT plans on deploying one 150 kW 
Power Buoy at EMEC, and another 
150 kW Power Buoy (the first of ten) at 
Reedsport, Oregon, during 2010.
Ocean Power Technologies (OPT) deve-
lops a point absorber called the Power 
Buoy rated 150 kW, OPT envisaged 
however higher capacity Power Buoys 
in the future. 
The Power Buoy consists of two bodies, 
the buoy seen to the right that follows 
the waves, and a submerged body inclu-
ding a reaction plate.
The reaction plate, sometimes referred 
to as the heave plate, has the task to 
keep the submerged body as vertically 
still as possible, and thus creating a 
reference for the moving buoy. 
Wavegen
Wavegen is a wholly owned subsidiary 
of Voith Hydro that develops shoreline 
and nearshore OWCs.
The first LIMPET (Land Installed Ma-
rine Power Energy Transformer) plant 
on Isle of Islay is designed for annual 
average wave climates of 15 – 25 kW/m 
and has a nameplate capacity of 500 
kW.
Wavegen and npower Renewables 
received consent in January 2009 to 
install 4 MW of OWC technology in a 
breakwater in the Siadar bay on the Isle 
of Lewis. The plant is planned to start 
operation in 2011.
Further, Wavegen is finalising a break-
water OWC WEC in Mutriku, Spain. 
This power plant consists of 16 turbines 
of each 18,5 kW (296 kW in total).
Oceanlinx
Oceanlinx is an Australian developer of 
OWC type WECs. 
The technology uses an Oceanlinx 
in-house developed turbine called the 
Denniss-Auld turbine.
The company has had three generations 
of their technology tested out at sea. 
The Mk1 was deployed in 2005 and 
decommissioned in 2009. 
The Mk2 was instrumented test unit 
that was in operation 2008 and 2009.
Just recently, in March 2010, Oceanlinx 
deployed their Mk3PC machine. This is 
a grid connected 3rd scale pre-commer-
cial device. 
Oceanlinx anticipates that a full-scale 
Mk3 WEC will have an installed capa-
city above 2,5 MW.
