OPT awarded $1.5m for higher output PowerBuoy

OCEAN POWER TECHNOLOGIES WINS NEW $1.5M AWARD

TO DEVELOP HIGHER OUTPUT POWERBUOY

Pennington, New Jersey - April 12, 2010 - Ocean Power Technologies, Inc. (Nasdaq: OPTT and London Stock Exchange AIM: OPT) ("OPT" or the "Company") announces that it has won a $1.5 million award from the US Department of Energy ("DoE") for the development of OPT's next generation PowerBuoy® wave power system.

The DoE grant will be used to help fund the scale-up of the power output per PowerBuoy from the current level of 150kW to 500kW. In addition, the technology development effort will focus on increasing the power extraction efficiency and a "Design-for-Manufacture" approach, which aims to achieve lower installed capital and energy costs that are expected to be competitive with energy based on fossil fuels.

Charles F. Dunleavy, Chief Executive Officer of the Company, said: "OPT's program of work under this award is in accord with the Department of Energy's objectives to increase the use of domestic marine resources for electric power generation and to enhance energy security, while improving the environment. OPT and its partners share these goals and are committed to dealing constructively with the challenges of climate change. We appreciate the DoE's confidence in our technical capabilities to commercialize wave power further."

This is the second award to OPT by the DoE. In 2008, OPT received $2.0 million to provide funding for the construction of a PB150 PowerBuoy to be deployed in connection with the Company's project at Reedsport, Oregon.

Issued to OPT under a competitive process, this latest award was made in support of innovative renewable water power technologies. The DoE is seeking to advance the commercial viability, market acceptance and environmental performance of marine and hydrokinetic technologies. Work under the award will be performed on an equal cost-sharing basis over a two-year period, subject to full expenditure authorization and incremental funding by the DoE.
