Power System
The TidGen
®
Power System generates emission-free electricity from tidal currents and connects directly into existing grids using smart grid technology. The power system consists of three major subsystems: shore-side power electronics, mooring system, and turbine generator unit (TGU) device.
In 2012, ORPC built and operated its TidGen
®
Power System in Cobscook Bay in Eastport and Lubec, Maine. It was the first revenue-generating, grid-connected tidal energy project in North America, and the first ocean energy project to deliver power to a utility grid anywhere in the Americas.
Features:
Low profile, advanced design cross-flow turbines
Operates underwater with no visible surface features
Encapsulated generator specifically designed for leak prevention and long life in subsea operations
Inbuilt passive and active buoyancy control
Non-linear control system for operating in turbulent conditions
Optimized drivetrain with minimal friction losses and high reliability
Buoyant tensioned mooring system reduces installation cost and time, and minimizes seabed footprint
Improved turbine extraction efficiencies approaching 45%
Advanced composite materials optimized for performance and component life
Designed to be deployed by locally available vessels, equipment and contractors
Compatible with utility and local community grids
