About: Ocean Renewable Power Company

Ocean Renewable Power Company (ORPC, Inc.) is a marine renewable energy company based in Portland, Maine. The company develops technologies which generate electricity from tidal, river, and ocean currents. The turbines are a cross-flow design in the helix shape of DNA with the axis of rotation perpendicular to the flow of water and work on the same principle as water wheels. As water flows, the turbine foils spin in the same direction producing mechanical power that a permanent magnet generator converts to electricity and then sends to the electrical grid via an underwater power cable and onshore power station. The TidGen® Power System (for tidal currents) and RivGen® Power System (for river and shallow tidal currents) are the company's trademarked systems.
