Every continent on the planet is surrounded by a cleaner, safer, more efficient answer to our energy needs. The power in ocean waves. Ocean Power Technologies (OPT) is a leading renewable energy company specializing in cost-effective, advanced, and environmentally sound offshore wave power technology. The electrical power generated by OPT's technology is key to meeting the energy needs of utilities, independent power producers and the public sector.

OPT's PowerBuoy® system extracts the natural energy in ocean waves, and is based on the integration of patented technologies in hydrodynamics, electronics, energy conversion and computer control systems. The PowerBuoy is a “smart” system capable of responding to differing wave conditions.

The result is a leading edge, ocean-tested, proprietary system which generates reliable, clean, and environmentally-beneficial electricity.

OPT's PowerBuoy® wave generation system uses a "smart," ocean-going buoy to capture and convert wave energy into low-cost, clean electricity.

The rising and falling of the waves off shore causes the buoy to move freely up and down. The resultant mechanical stroking is converted via a sophisticated power take-off to drive an electrical generator. The generated power is transmitted ashore via an underwater power cable.

A 10-Megawatt OPT power station would occupy only approximately 30 acres
(0.125 square kilometers) of ocean space.

Sensors on the PowerBuoy® continuously monitor the performance of the various subsystems and surrounding ocean environment. Data is transmitted to shore in real time. In the event of very large oncoming waves, the system automatically locks-up and ceases power production. When the wave heights return to normal, the system unlocks and recommences energy conversion and transmission of the electrical power ashore.
• Buoys are spaced to maximize energy capture.

• Rugged, simple steel construction.

• Utilizes conventional mooring systems.

• Simple installation using existing marine vessels and infrastructure.

• Scalable to large power stations (100+ MW)
