# List of tidal power stations

This article lists most power stations that run on tidal power, both tidal range (impoundment via a barrage) and tidal stream (harnessing currents). Since tidal stream generators are an immature technology, no technology has yet emerged as the clear standard. A large variety of designs are being experimented with, with some very close to large scale deployment. Hence, the following page lists stations of different technologies. While only a few schemes are operational or under construction, many more have been proposed, but some of these plans may never be constructed.
