NEW YORK (TheStreet) -- Ocean Power Technologies (OPTT) - Get Report stock is spiking by 257.53% to $5.22 on heavy trading volume early Wednesday afternoon, after the company entered into a PB3 PowerBuoy lease agreement with Mitsui Engineering and Shipbuilding (MIESF).

The PowerBuoy systems generate electricity by harnessing the renewable energy of ocean waves.

"We believe that the deployment under this agreement could provide access to a potentially huge market in Japan and the surrounding areas, and we're looking forward to potentially leveraging these events with other interested parties," CEO George Kirby said in a statement.
