Tidal power systems have been under investigation for many years. The earliest method to generate power was with 'barrage' systems, which required the construction of dams across inlets and bays. Gates in the dams allowed the basin to fill during high tide, then the gates would be closed, and the basin would be allowed to drain out through turbines to generate power. However, the environmental impacts of these systems, along with the cost and the relative inefficiency, have kept them from much further development. There are some 'barrage' installations still in operation in Canada and in France, but no new projects are planned.
