OPT previously said design was under way and some construction had begun on its PB150 PowerBuoy wave energy unit for deployment at EMEC. (HNN 3/26/08) In 2007, the government of Scotland awarded OPT 598,000 pounds (US$1.16 million), for a 150-kW PowerBuoy, which moves up and down on a central spar as waves pass by.
OPT said the berth agreement provides for the deployment and operation of its PowerBuoys as well as their connection to the wave energy berth's dedicated 2-MW subsea cable already installed and connected to Scotland's grid. The agreement also allows OPT to sell power to the grid up to 2 MW. OPT said it might utilize EMEC for deployment and testing of other PowerBuoy technology.
The developer said its first buoy is expected to be ready for grid connection at EMEC in 2009.
OPT expects to deploy the PB150 PowerBuoy in projects in development in Spain, southwest England, France, the United States, and Australia.
