TidGen® Power System

TidGen® 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.
