OCEAN POWER TECHNOLOGIES ACHIEVES WORLD'S FIRST LLOYD'S REGISTER CERTIFICATION FOR UTILITY SCALE PB150 WAVE POWER DEVICE

Pennington, New Jersey - January 11, 2011 - Ocean Power Technologies, Inc. (Nasdaq: OPTT and London Stock Exchange AIM: OPT) ("OPT" or the "Company") is pleased to announce that it has achieved an independent certification for its utility scale PowerBuoy®, the PB150, by the internationally respected Lloyd's Register.

The certificate from Lloyd's Register confirms that the PB150 design complies with the requirements of Lloyd's 1999 Rules and Regulations for the Classification of Floating Offshore Installations at a Fixed Location. This provides independent, third-party assurance on the design of the PB150 PowerBuoy for its intended use, as analyzed against international standards.

Ross Wigg, Renewables Leader at Lloyd's Register, said: "Ocean Power Technologies is the first wave energy device developer that has approached Lloyd's Register for its assurance services. Our extensive experience in the offshore energy sector is critical to the fast developing offshore renewable developments and our certification of the PowerBuoy is a significant step for Ocean Power Technologies' product offering. It demonstrates their commitment to providing safe and efficient products to generate low-cost, clean energy." Wigg continued: "The process included detailed design analysis and appraisals, including the PB150's structure, hydrodynamics, mooring and anchoring."

Charles F. Dunleavy, Chief Executive Officer of OPT, said: "To have met the stringent requirements of Lloyd's Register for certification of our PB150 PowerBuoy is testament to the quality of our engineers and delivery processes, and draws on our sixteen-year experience in developing wave energy systems to operate and survive in the demanding ocean environment. Lloyd's Register has an outstanding reputation for providing its analysis and appraisals to the marine, offshore energy and shipping industries. This is a major milestone in the commercialization of our PowerBuoy technology, and gives our customers, investors, and project partners further confidence that our products are market ready and robust."

The achievement of this certification for the PB150 PowerBuoy follows from the Company's successful installation in December 2009 of its PB40 PowerBuoy in Oahu, Hawaii and its connection to the grid. That project is part of OPT's on-going program with the US Navy to develop and test the PowerBuoy technology, and has contributed to the roll-out of OPT's next generation PB150 system for the electrical utility markets. The first PB150 device is currently being prepared for transit (subject to weather conditions) to a location off the coast of Inverness, Scotland for planned ocean testing.

In July 2007, OPT announced that its PowerBuoy interface with the electrical utility power grid had been certified as compliant with international standards. An independent laboratory, Intertek Testing Services, provided testing and evaluation services to certify that OPT systems comply with designated national and international standards, including UL1741 and IEEE1547.
