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.

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.

Alderney tidal plant	400	Guernsey	49°42′52″N 2°12′19″W	OpenHydro ceased trading	[28][29]
Kaipara Tidal Power Station	200	NZ	36°25′S 174°10′E	Project paused in 2013 and consent lapsed in 2021	[30]
Pempa’q In-Stream Tidal Energy Project	1.26	Canada	45°20′36″N 64°23′34″W	Development halted following permitting issues	[31][32][33][34]
