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, however some of these plans may never be constructed.
The following table lists tidal power stations that are in operation:
The following table lists tidal power stations that are currently under construction as of the date in each cited source.

These schemes were proposed, but will not now go ahead in the form originally proposed because the developer has ceased trading or the technology is no longer being developed.
