Ocean Renewable Power Company (ORPC), an industry leader in tidal, river and deep-water ocean current energy technology and projects, announced today that its Beta Power System, the largest ocean energy "power plant" ever installed in U.S. waters, has successfully generated grid-compatible power from tidal currents at its Cobscook Bay site in Eastport, Maine.
The system’s core component, the proprietary Turbine
Generator Unit, or TGU, is deployed below ORPC’s world-class research and
testing vessel, the Energy Tide 2, and has a maximum design capacity of 60
kilowatts. Performance test results show that the TGU’s electrical output meets
or exceeds expectations for the full range of current velocities encountered.
ORPC will use the data obtained from the Beta Power System to fine tune the
design of its commercial TidGen™ Power System, planned for installation in
Eastport in late 2011. The TidGen™ Power System will be connected to the
“Proving the efficacy of the Beta Power System and its
ability to generate grid-compatible power day in and day out is a huge
ORPC’s Beta Power System incorporates significant new advancements and technological innovations. These include the TGU’s proprietary advanced design cross-flow turbines, engineered with 100 percent composite materials, its permanent magnet generator, a substantially composite support frame, and a power electronics system that converts the generator’s variable output to grid-compatible power.
Through its three-year partnership with the
Over the next two months, ORPC will also be demonstrating
how tidal energy can be delivered to the U.S. Coast Guard for use at its
Eastport station through a battery electrical supply system that is charged
aboard the Energy Tide 2. This is the first application of tidal energy by a
federal agency. “The Coast Guard in
ORPC is one of the few companies in the world to have generated electricity from ocean currents without using dams or impoundments. The company holds FERC preliminary permits and is in the process of obtaining FERC pilot project licenses for tidal energy sites in Maine and Alaska, which have been designated world-class tidal resources by the World Energy Congress. ORPC’s community outreach efforts in Eastport have been cited as the model for ocean energy development by the Governor of Maine’s Ocean Energy Task Force. ORPC’s work is funded in part by Maine Technology Institute and the U.S. Department of Energy.
