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.
Tidal power stations
Operational
The following table lists tidal power stations that are in operation:
Scotland
Under construction
The following table lists tidal power stations that are currently under construction as of the date in each cited source.
| Station | Capacity (MW) | Country | Location | Start | Ref |
|---|---|---|---|---|---|
| Morlais (West Anglesey Demonstration Zone) | 240 MW potential |  United Kingdom Wales

53°18′23″N 4°43′00″W / 53.30639°N 4.71667°W / 53.30639; -4.71667 (Morlais (West Anglesey Demonstration Zone)) | Consented 2021 1st tidal device 2026 |
Proposed
The following table lists tidal power stations that are at a proposal stage. Some of these scheme may not go ahead, but have not formally been cancelled.
Historical proposals
These schemes were proposed, but will not now go ahead in the form originally proposed because the developer has ceased trading, the technology is no longer being developed, or the consent has lapsed.
