Waves Power US Grid for the First Time

OPT's PB40 PowerBuoy was hooked up to the grid at the Marine Corps Base Hawaii as part of the firm's programme with the US Navy to test wave energy technology. The connection demonstrates the device's ability to produce utility-grade renewable energy that can be transmitted to the grid according to international and national standards, says the firm.

“Grid connection is another significant milestone in demonstrating the potential for commercial status of our PowerBuoy technology,” said OPT’s CEO Charles F. Dunleavy.

The PowerBuoy was deployed three-quarters of a mile off the coast of Oahu in December 2009 at a depth of 100 feet. Since then the device has produced power from more than 3 million power take-off cycles and 4,400 hours of operation.

The project has also undergone extensive environmental assessment by an independent environmental firm in accordance the National Environment Policy Act (NEPA) that resulted in a Finding of No Significant Impact (FONSI), says OPT.
