PB150 PowerBuoy

OPT’s newest addition to its product line is the PB150 PowerBuoy®. This utility scale, 150 kiloWatt (kW) PowerBuoy is being fabricated in Scotland and will be deployed in 2010 at the European Marine Energy Centre in Orkney Isles, Scotland. A second PB150 PowerBuoy is also planned to be ready for deployment in 2010 as the first of ten PowerBuoys at Reedsport, Oregon. The deployment of these two PowerBuoys in the Atlantic and Pacific Oceans will mark a milestone in the Company’s commercial development. It will be the first time two of the same scale utility PowerBuoys are deployed in multiple locations.

The PB150 PowerBuoy offers many features for wave energy projects. It will generate power with wave heights between 1.5 and 7 meters (4.9 to 22.9 feet). OPT’s mooring approach and PowerBuoy structure permit deployment of the PowerBuoy system across a wide combination of storm wave, tidal, and current conditions, making it suitable for many wave climates. The PB150 is typically configured in two to three row arrays, minimizing the footprint of the project.

The PB150 PowerBuoy offers a sustained maximum peak-rated output of 150 kW and a power factor of -0.9 to +0.9. Typical capacity factors for the PB150 are between 30% to 50%, depending on location. The PowerBuoy provides grid quality electricity and is certified meeting all required interconnection standards. The PowerBuoy has a fiber optic communications and Supervisory Control and Data Acquisition (SCADA) capabilities. The PowerBuoy also has “black start” capability.

OPT has also developed an Underwater Substation Pod (USP) for which a patent is pending, which can aggregate the electrical output from up to ten (10) PB150 PowerBuoys into a single transmission cable to shore. This approach minimizes costs of submarine transmission cable to the shore based interconnection. The USP provides control and SCADA capability for all connected PowerBuoys.
